Review Online Boutique's [purpose](/docs/purpose.md) and [product requirements](/docs/product-requirements.md).\n1. If your proposed changes **do not align** with the purpose and product requirements of Online Boutique, you may be asked to instead maintain your own fork of this repository.\n1. For **small changes** (such as a bug fixes or spelling corrections):\n 1. Fork this repository and submit a [pull request](https://help.github.com/articles/about-pull-requests/).\n 1. Wait for a maintainer of this repository to review your change.\n1. For **bigger changes**:\n 1. Create a [GitHub issue](https://github.com/GoogleCloudPlatform/microservices-demo/issues/new/choose) describing the change **before** working on the implementation. This is important to avoid potentially having to discard your development efforts.\n 1. Wait for a maintainer of this repository to review your GitHub issue. For significantly complex proposals, you may be asked to start a Google Doc to discuss design decisions.\n\nIf you have any questions, please [create a GitHub issue](https://github.com/GoogleCloudPlatform/microservices-demo/issues/new/choose).\n" }, { "path": ".github/ISSUE_TEMPLATE/bug-report.md", "content": "---\nname: Bug report\nabout: Create a report to help us improve\ntitle: ''\nlabels: ''\nassignees: ''\n\n---\n\n### Describe the bug \n\n\n### To Reproduce \n\n\n\n\n\n### Logs \n\n\n### Screenshots \n\n\n### Environment \n\n\n\n\n### Additional context \n\n\n### Exposure \n\n" }, { "path": ".github/ISSUE_TEMPLATE/feature-request.md", "content": "---\nname: Feature request\nabout: Suggest an idea for this project\ntitle: ''\nlabels: ''\nassignees: ''\n\n---\n\n### Describe request or inquiry \n\n\n### What purpose/environment will this feature serve? \n\n" }, { "path": ".github/ISSUE_TEMPLATE/other.md", "content": "---\nname: Other\nabout: Have a question or need clarification?\ntitle: ''\nlabels: ''\nassignees: ''\n\n---\n### Write down your inquiry \n\n" }, { "path": ".github/SECURITY.md", "content": "# Security Policy\n\nTo report a security issue, please use [g.co/vulnz](https://g.co/vulnz).\n\nThe Google Security Team will respond within 5 working days of your report on g.co/vulnz.\n\nWe use g.co/vulnz for our intake, and do coordination and disclosure here using GitHub Security Advisory to privately discuss and fix the issue.\n" }, { "path": ".github/auto-approve.yml", "content": "# Copyright 2023 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\n# https://github.com/googleapis/repo-automation-bots/tree/main/packages/auto-approve\nprocesses:\n -

These runners are GCE instances (virtual machines) that, for every open Pull Request in the repo, run the code test pipeline, deploy test pipeline, and (on main) deploy the latest version of the app to [cymbal-shops.retail.cymbal.dev](https://cymbal-shops.retail.cymbal.dev)\n\nWe also host a test GKE cluster, which is where the deploy tests run. Every PR has its own namespace in the cluster.\n\n## Workflows\n\n**Note**: In order for the current CI/CD setup to work on your pull request, you must branch directly off the repo (no forks). This is because the Github secrets necessary for these tests aren't copied over when you fork.\n\n### Code Tests - [ci-pr.yaml](ci-pr.yaml)\n\nThese tests run on every commit for every open PR, as well as any commit to main / any release branch. Currently, this workflow runs only Go unit tests.\n\n\n### Deploy Tests- [ci-pr.yaml](ci-pr.yaml)\n\nThese tests run on every commit for every open PR, as well as any commit to main / any release branch. This workflow:\n\n1. Creates a dedicated GKE namespace for that PR, if it doesn't already exist, in the PR GKE cluster.\n2. Uses `skaffold run` to build and push the images specific to that PR commit. Then skaffold deploys those images, via `kubernetes-manifests`, to the PR namespace in the test cluster.\n3. Tests to make sure all the pods start up and become ready.\n4. Gets the LoadBalancer IP for the frontend service.\n5. Comments that IP in the pull request, for staging.\n\n### Push and Deploy Latest - [push-deploy](push-deploy.yml)\n\nThis is the Continuous Deployment workflow, and it runs on every commit to the main branch. This workflow:\n\n1. Builds the container images for every service, tagging as `latest`.\n2. Pushes those images to Google Container Registry.\n\nNote that this workflow does not update the image tags used in `release/kubernetes-manifests.yaml` - these release manifests are tied to a stable `v0.x.x` release.\n\n### Cleanup - [cleanup.yaml](cleanup.yaml)\n\nThis workflow runs when a PR closes, regardless of whether it was merged into main. This workflow deletes the PR-specific GKE namespace in the test cluster.\n\n## Appendix - Creating a new Actions runner\n\nShould one of the two self-hosted Github Actions runners (GCE instances) fail, or you want to add more runner capacity, this is how to provision a new runner. Note that you need IAM access to the admin Online Boutique GCP project in order to do this.\n\n1. Create a GCE instance.\n - VM should be at least n1-standard-4 with 50GB persistent disk\n - VM should use custom service account with permissions to: access a GKE cluster, create GCS storage buckets, and push to GCR.\n2. SSH into new VM through the Google Cloud Console.\n3. Install project-specific dependencies, including go, docker, skaffold, and kubectl:\n\n```\nwget -O - https://raw.githubusercontent.com/GoogleCloudPlatform/microservices-demo/main/.github/workflows/install-dependencies.sh | bash\n```\n\nThe instance will restart when the script completes in order to finish the Docker install.\n\n4. SSH back into the VM.\n\n5. Follow the instructions to add a new runner on the [Actions Settings page](https://github.com/GoogleCloudPlatform/microservices-demo/settings/actions) to authenticate the new runner\n6. Start GitHub Actions as a background service:\n```\nsudo ~/actions-runner/svc.sh install ; sudo ~/actions-runner/svc.sh start\n```\n" }, { "path": ".github/workflows/ci-main.yaml", "content": "# Copyright 2020 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\nname: \"Continuous Integration -

Ensure you have the following requirements:\n - [Google Cloud project](https://cloud.google.com/resource-manager/docs/creating-managing-projects#creating_a_project).\n - Shell environment with `gcloud`, `git`, and `kubectl`.\n\n2. Clone the latest major version.\n\n ```sh\n git clone --depth 1 --branch v0 https://github.com/GoogleCloudPlatform/microservices-demo.git\n cd microservices-demo/\n ```\n\n The `--depth 1` argument skips downloading git history.\n\n3. Set the Google Cloud project and region and ensure the Google Kubernetes Engine API is enabled.\n\n ```sh\n export PROJECT_ID=\n export REGION=us-central1\n gcloud services enable container.googleapis.com \\\n --project=${PROJECT_ID}\n ```\n\n Substitute `` with the ID of your Google Cloud project.\n\n4. Create a GKE cluster and get the credentials for it.\n\n ```sh\n gcloud container clusters create-auto online-boutique \\\n --project=${PROJECT_ID} --region=${REGION}\n ```\n\n Creating the cluster may take a few minutes.\n\n5. Deploy Online Boutique to the cluster.\n\n ```sh\n kubectl apply -f ./release/kubernetes-manifests.yaml\n ```\n\n6. Wait for the pods to be ready.\n\n ```sh\n kubectl get pods\n ```\n\n After a few minutes, you should see the Pods in a `Running` state:\n\n ```\n NAME READY STATUS RESTARTS AGE\n adservice-76bdd69666-ckc5j 1/1 Running 0 2m58s\n cartservice-66d497c6b7-dp5jr 1/1 Running 0 2m59s\n checkoutservice-666c784bd6-4jd22 1/1 Running 0 3m1s\n currencyservice-5d5d496984-4jmd7 1/1 Running 0 2m59s\n emailservice-667457d9d6-75jcq 1/1 Running 0 3m2s\n frontend-6b8d69b9fb-wjqdg 1/1 Running 0 3m1s\n loadgenerator-665b5cd444-gwqdq 1/1 Running 0 3m\n paymentservice-68596d6dd6-bf6bv 1/1 Running 0 3m\n productcatalogservice-557d474574-888kr 1/1 Running 0 3m\n recommendationservice-69c56b74d4-7z8r5 1/1 Running 0 3m1s\n redis-cart-5f59546cdd-5jnqf 1/1 Running 0 2m58s\n shippingservice-6ccc89f8fd-v686r 1/1 Running 0 2m58s\n ```\n\n7. Access the web frontend in a browser using the frontend's external IP.\n\n ```sh\n kubectl get service frontend-external | awk '{print $4}'\n ```\n\n Visit `http://EXTERNAL_IP` in a web browser to access your instance of Online Boutique.\n\n8. Congrats! You've deployed the default Online Boutique. To deploy a different variation of Online Boutique (e.g., with Google Cloud Operations tracing, Istio, etc.), see [Deploy Online Boutique variations with Kustomize](#deploy-online-boutique-variations-with-kustomize).\n\n9. Once you are done with it, delete the GKE cluster.\n\n ```sh\n gcloud container clusters delete online-boutique \\\n --project=${PROJECT_ID} --region=${REGION}\n ```\n\n Deleting the cluster may take a few minutes.\n\n## Additional deployment options\n\n- **Terraform**: [See these instructions](/terraform) to learn how to deploy Online Boutique using [Terraform](https://www.terraform.io/intro).\n- **Istio / Cloud Service Mesh**: [See these instructions](/kustomize/components/service-mesh-istio/README.md) to deploy Online Boutique alongside an Istio-backed service mesh.\n- **Non-GKE clusters (Minikube, Kind, etc)**: See the [Development guide](/docs/development-guide.md) to learn how you can deploy Online Boutique on non-GKE clusters.\n- **AI assistant using Gemini**: [See these instructions](/kustomize/components/shopping-assistant/README.md) to deploy a Gemini-powered AI assistant that suggests products to purchase based on an image.\n- **And more**: The [`/kustomize` directory](/kustomize) contains instructions for customizing the deployment of Online Boutique with other variations.\n\n## Documentation\n\n- [Development](/docs/development-guide.md) to learn how to run and develop this app locally.\n\n## Demos featuring Online Boutique\n\n- [Security hardening of the OnlineBoutique sample apps with the Docker Hardened Images (DHI)](https://medium.com/google-cloud/security-hardening-of-the-onlineboutique-sample-apps-with-docker-hardened-images-dhi-ca1fad348343)\n- [alpine, distroless or scratch?](https://medium.com/google-cloud/alpine-distroless-or-scratch-caac35250e0b)\n- [Platform Engineering in action: Deploy the Online Boutique sample apps with Score and Humanitec](https://medium.com/p/d99101001e69)\n- [The new Kubernetes Gateway API with Istio and Anthos Service Mesh (ASM)](https://medium.com/p/9d64c7009cd)\n- [Use Azure Redis Cache with the Online Boutique sample on AKS](https://medium.com/p/981bd98b53f8)\n- [Sail Sharp, 8 tips to optimize and secure your .NET containers for Kubernetes](https://medium.com/p/c68ba253844a)\n- [Deploy multi-region application with Anthos and Google cloud Spanner](https://medium.com/google-cloud/a2ea3493ed0)\n- [Use Google Cloud Memorystore (Redis) with the Online Boutique sample on GKE](https://medium.com/p/82f7879a900d)\n- [Use Helm to simplify the deployment of Online Boutique, with a Service Mesh, GitOps, and more!](https://medium.com/p/246119e46d53)\n- [How to reduce microservices complexity with Apigee and Anthos Service Mesh](https://cloud.google.com/blog/products/application-modernization/api-management-and-service-mesh-go-together)\n- [gRPC health probes with Kubernetes 1.24+](https://medium.com/p/b5bd26253a4c)\n- [Use Google Cloud Spanner with the Online Boutique sample](https://medium.com/p/f7248e077339)\n- [Seamlessly encrypt traffic from any apps in your Mesh to Memorystore (redis)](https://medium.com/google-cloud/64b71969318d)\n- [Strengthen your app's security with Cloud Service Mesh and Anthos Config Management](https://cloud.google.com/service-mesh/docs/strengthen-app-security)\n- [From edge to mesh: Exposing service mesh applications through GKE Ingress](https://cloud.google.com/architecture/exposing-service-mesh-apps-through-gke-ingress)\n- [Take the first step toward SRE with Cloud Operations Sandbox](https://cloud.google.com/blog/products/operations/on-the-road-to-sre-with-cloud-operations-sandbox)\n- [Deploying the Online Boutique sample application on Cloud Service Mesh](https://cloud.google.com/service-mesh/docs/onlineboutique-install-kpt)\n- [Anthos Service Mesh Workshop: Lab Guide](https://codelabs.developers.google.com/codelabs/anthos-service-mesh-workshop)\n- [KubeCon EU 2019 -

Create a new directory\n\nCreate a new directory for your microservice within the `src/` directory. The directory name should be the name of your microservice.\n\n## 2. Add source code\n\nPlace your microservice's source code inside the newly created directory. The structure of this directory should follow the conventions of the existing microservices. For example, a Python-based service would include at minimum the following files:\n\n- `README.md`: The service's description and documentation.\n- `main.py`: The application's entry point.\n- `requirements.in`: A list of Python dependencies.\n- `Dockerfile`: To containerize the application.\n\nTake a look at existing microservices for inspiration.\n\n## 3. Create a Dockerfile\n\nCreate a `Dockerfile` in your microservice's directory. This file will define the steps to build a container image for your service.\n\nRefer to this example and tweak based on your new service's needs: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/src/frontend/Dockerfile\n\n## 4. Create Kubernetes manifests\n\nCreate a new directory under `kustomize/components/` in the root of the repository for your microservice. Inside this directory, add the necessary Kubernetes YAML files for your new microservice. This typically includes:\n\n- A **Deployment** to manage your service's pods.\n- A **Service** to expose your microservice to other services within the cluster.\n\nEnsure you follow the existing naming conventions and that the container image specified in the Deployment matches the one built by your `cloudbuild.yaml` and `skaffold.yaml` files.\n\nRefer to this example and tweak based on your new service's needs: https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/kustomize/components/shopping-assistant\n\n## 5. Update the root `kustomization.yaml` file\n\nAdd your newly created component to the root kustomization file so it gets picked up by the deployment cycle.\n\nThe file is available here: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/kustomize/kustomization.yaml\n\n## 6. Update the root `skaffold.yaml`\n\nAdd your newly created service to the root skaffold file so the images build correctly.\n\nThe file is available here: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/skaffold.yaml\n\n## 7. Update the Helm chart\n\nAdd your newly created service to the Helm chart templates and default values.\n\nThe chart is available here: https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/helm-chart\n\n## 8. Update the documentation\n\nFinally, update the project's documentation to reflect the addition of your new microservice. This may include:\n\n- Adding a section to the main `README.md` if the service introduces significant new functionality.\n- Updating the architecture diagrams in the `docs/img` directory.\n- Adding a new document in the `docs` directory if the service requires detailed explanation.\n" }, { "path": "docs/cloudshell-tutorial.md", "content": "# Online Boutique quickstart\n\nThis tutorial shows you how to deploy **[Online Boutique](https://github.com/GoogleCloudPlatform/microservices-demo)** to a Kubernetes cluster.\n\nYou'll be able to run Online Boutique on:\n- a local **[minikube](https://minikube.sigs.k8s.io/docs/)** cluster, which comes built in to the Cloud Shell instance\n- a **[Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine)** cluster using a new or existing [Google Cloud project](https://cloud.google.com/resource-manager/docs/creating-managing-projects#creating_a_project)\n\nLet's get started!\n\n\n## Kubernetes cluster setup\n\nSet up a Kubernetes cluster using the instructions below for either **minikube** or **GKE**.\n\n### Minikube instructions\n\nMinikube creates a local Kubernetes cluster on Cloud Shell.\n\n1. Click minikube on the status bar located at the bottom of the editor window.\n\n2. The command palette will prompt you to choose which minikube cluster to control. Select **minikube** and, in the next prompt, click **Start** if the cluster has not already been started. \n\n3. If prompted, authorize Cloud Shell to make a GCP API call with your credentials.\n\n*It may take a few minutes for minikube to finish starting.*\n\nOnce minikube has started, you're ready to move on to the next step. \n\n### GKE instructions\n\nIn order to create a GKE cluster, you'll need to **[create a Google Cloud project](https://cloud.google.com/resource-manager/docs/creating-managing-projects#creating_a_project)** or use an existing project.\n\n1. Access the command palette by going to **View > Find Command**.\n\n2. Run the command **\"Cloud Code: Create GKE cluster\"**.\n\n3. Select your GCP project. \n\n4. Apply the following configurations in the GKE wizard: \n> - Zone: us-central1-b\n> - Cluster name: onlineboutique\n> - Node count: 4\n> - Machine type: e2-standard-2\n\n5. Click **Create Cluster**. Once your cluster has been created successfully, you can move on to the next step.\n\n\n## Run on Kubernetes\n\nNow you can run Online Boutique on your Kubernetes cluster!\n\n1. Launch the Cloud Code menu from the status bar and select Run on Kubernetes.\n\n2. If prompted to select a Skaffold Profile, select **[default]**.\n\n3. Select **Yes** to confirm your current context.\n\n4. If you're using a GKE cluster, you'll need to confirm your container image registry.\n\n5. If prompted, authorize Cloud Shell to make a GCP API call with your credentials.\n\nCloud Code uses configurations defined in skaffold.yaml to build and deploy the app. *It may take a few minutes for the deploy to complete.*\n\n6. Once the app is running, the local URLs will be displayed in the Output terminal. \n\n7. To access your Online Boutique frontend service, click on the Web Preview button in the upper right of the editor window.\n\n8. Select **Change Port** and enter '4503' as the port, then click **Change and Preview**. Your app will open in a new window. \n\n\n## Stop the app\n\nTo stop running the app: \n\n1. Go to the Debug view \n\n2. Click the **Stop** icon.\n\n3. Select **Yes** to clean up deployed resources. \n\nYou can start, stop, and debug apps from the Debug view.\n\n### Clean up\n\nIf you've deployed your app to a GKE cluster in your Google Cloud project, you'll want to delete the cluster to avoid incurring charges.\n\n1. Navigate to the Cloud Code - Kubernetes view in the Activity bar.\n\n2. Under the Google Kubernetes Engine Explorer tab, right-click on your cluster and select **Delete Cluster**.\n\n\n## Conclusion\n\n\n\nCongratulations!

(for Option 1 - GKE)\n- [Minikube](https://minikube.sigs.k8s.io/docs/start/) (optional for Option 2 - Local Cluster)\n- [Kind](https://kind.sigs.k8s.io/) (optional for Option 2 - Local Cluster)\n\n## Option 1: Google Kubernetes Engine (GKE)\n\n> 💡 Recommended if you're using Google Cloud and want to try it on\n> a realistic cluster. **Note**: If your cluster has Workload Identity enabled, \n> [see these instructions](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity#enable)\n\n1. Create a Google Kubernetes Engine cluster and make sure `kubectl` is pointing\n to the cluster.\n\n ```sh\n gcloud services enable container.googleapis.com\n ```\n\n ```sh\n gcloud container clusters create-auto demo --region=us-central1\n ```\n\n ```\n kubectl get nodes\n ```\n\n2. Enable Artifact Registry (AR) on your GCP project and configure the\n `docker` CLI to authenticate to AR:\n\n ```sh\n gcloud services enable artifactregistry.googleapis.com\n ```\n\n ```sh\n gcloud artifacts repositories create microservices-demo \\\n --repository-format=docker \\\n --location=us \\\n ```\n\n ```sh\n gcloud auth configure-docker -q \n ```\n\n3. In the root of this repository, run:\n\n ```\n skaffold run --default-repo=us-docker.pkg.dev/PROJECT_ID/microservices-demo\n ```\n \n Where `PROJECT_ID` is replaced by your Google Cloud project ID.\n\n This command:\n\n - Builds the container images.\n - Pushes them to AR.\n - Applies the `./kubernetes-manifests` deploying the application to\n Kubernetes.\n\n **Troubleshooting:** If you get \"No space left on device\" error on Google\n Cloud Shell, you can build the images on Google Cloud Build: [Enable the\n Cloud Build\n API](https://console.cloud.google.com/flows/enableapi?apiid=cloudbuild.googleapis.com),\n then run `skaffold run -p gcb --default-repo=us-docker.pkg.dev/[PROJECT_ID]/microservices-demo` instead.\n\n4. Find the IP address of your application, then visit the application on your\n browser to confirm installation.\n\n kubectl get service frontend-external\n\n5. Navigate to `http://EXTERNAL-IP` to access the web frontend.\n\n## Option 2 - Local Cluster \n\n1. Launch a local Kubernetes cluster with one of the following tools:\n\n - To launch **Minikube** (tested with Ubuntu Linux). Please, ensure that the\n local Kubernetes cluster has at least:\n - 4 CPUs\n - 4.0 GiB memory\n - 32 GB disk space\n\n ```shell\n minikube start --cpus=4 --memory 4096 --disk-size 32g\n ```\n\n - To launch **Docker for Desktop** (tested with Mac/Windows).

Run `kubectl get nodes` to verify you're connected to the respective control plane.\n\n3. Run `skaffold run` (first time will be slow, it can take ~20 minutes).\n This will build and deploy the application. If you need to rebuild the images\n automatically as you refactor the code, run `skaffold dev` command.\n\n4. Run `kubectl get pods` to verify the Pods are ready and running.\n\n5. Run `kubectl port-forward deployment/frontend 8080:8080` to forward a port to the frontend service.\n\n6. Navigate to `localhost:8080` to access the web frontend.\n\n## Adding a new microservice\n\nIn general, the set of core microservices for Online Boutique is fairly complete and unlikely to change in the future, but it can be useful to add an additional optional microservice that can be deployed to complement the core services.\n\nSee the [Adding a new microservice](adding-new-microservice.md) guide for instructions on how to add a new microservice.\n\n## Cleanup\n\nIf you've deployed the application with `skaffold run` command, you can run\n`skaffold delete` to clean up the deployed resources.\n" }, { "path": "docs/product-requirements.md", "content": "## Product Requirements\n\nThis document contains a list of requirements that every change made to this repository should meet.\nEvery change must:\n1. Preserve the golden user journey taken by Kubernetes beginners.\n1. Preserve the simplicity of demos.\n1. Preserve the simplicity of the GKE quickstart.\n\nThese requirements are about the default deployment (default configuration) of Online Boutique.\nChanges that will violate any of these rules should not be built into the default configuration of Online Boutique.\nSuch changes should be opt-in only — ideally, as a [Kustomize Component](https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/kustomize) if they align with the [purpose of Online Boutique](/docs/purpose.md).\n\n### 1. Preserve the golden user journey taken by Kubernetes beginners\n\nThe following statement about Online Boutique should always be true:\n\n> A user outside of Google can deploy Online Boutique's default configuration on a [_kind_ Kubernetes cluster](https://kind.sigs.k8s.io/).\n\nThis statement describes the golden user journey that we expect new Kubernetes users to take while onboarding to Online Boutique.\n\nBeing able to run Online Boutique on a _kind_ cluster ensures that Online Boutique is free and cloud-agnostic. This is aligned with [Google's mission](https://about.google/) of making information universally accessible and useful. To be specific, Online Boutique should be useful and accessible to developers that are new to Kubernetes.\n\n### 2. Preserve the simplicity of demos\n\nNew changes should not complicate the primary user journey showcased in live demos and tutorials.\n\nToday, the primary user journey is as follows:\n1. Visit Online Boutique on a web browser.\n2. Select an item from the homepage and add the item to the cart.\n3. The checkout form is pre-populated with placeholder data (e.g. the shipping address).\n4. The user checks out and completes the order.\n\n### 3. Preserve the simplicity of the GKE quickstart\n\nNew changes should not add additional complexity in the [main Online Boutique quickstart](https://github.com/GoogleCloudPlatform/microservices-demo#quickstart-gke).\n\nIn particular, new changes should not add extra required steps or additional required tools in that quickstart.\n\nIdeally, extensions to Online Boutique's default functionality (such as a new microservice or a new cloud service integration) should be added as a [Kustomize Component](https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/kustomize/components) which users can optionally opt into.\n" }, { "path": "docs/purpose.md", "content": "## Purpose\n\nToday, the primary purpose of Online Boutique is to demonstrate:\n\n* [Google Kubernetes Engine (GKE)](https://cloud.google.com/kubernetes-engine)\n* [Anthos](https://cloud.google.com/anthos)\n* [Google Cloud Operations](https://cloud.google.com/products/operations)\n* tools and technologies commonly used alongside the above products\n\nwhile being accessible and useful to all new Kubernetes users.\n\n### Why does the purpose matter?\n\nWe filter and prioritize the work to be done in this repository based on the purpose defined above.\nIf you wish to make changes to this repository that do not align with the above purpose, we encourage you to maintain your own fork of Online Boutique.\n" }, { "path": "docs/releasing/README.md", "content": "# Releasing Online Boutique\n\nThis document walks through the process of creating a new release of Online Boutique.\n\n## Prerequisites for tagging a release\n\n1. Choose the logical [next release tag](https://github.com/GoogleCloudPlatform/bank-of-anthos/releases), using [semantic versioning](https://semver.org/): `vX.Y.Z`.\n\n If this release includes significant feature changes, update the minor version (`Y`). Otherwise, for bug-fix releases or standard quarterly release, update the patch version `Z`).\n\n2. Ensure that the following commands are in your `PATH`:\n - `gsed` (found in the `gnu-sed` Brew package for macOS, or by symlinking `sed` for Linux)\n - `gcloud`\n - `helm`\n\n3. Make sure that your `gcloud` is authenticated:\n\n ```sh\n gcloud auth login\n gcloud auth configure-docker us-central1-docker.pkg.dev\n ```\n\n## Create and tag the new release\n\nRun the `make-release.sh` script found inside the `docs/releasing/` directory:\n\n```sh\n# assuming you are inside the root path of the bank-of-anthos repository\nexport TAG=vX.Y.Z # This is the new version (e.g. `v0.3.5`)\nexport REPO_PREFIX=us-central1-docker.pkg.dev/google-samples/microservices-demo # This is the Docker repository for tagged images\nexport PROJECT_ID=google-samples # This is the Google Cloud project for the release CI\n./docs/releasing/make-release.sh\n```\n\nThis script does the following:\n1. Uses `make-docker-images.sh` to build and push a Docker image for each microservice to the previously specified repository.\n2. Uses `make-release-artifacts.sh` to regenerates (and update the image $TAGS) YAML file at `./release/kubernetes-manifests.yaml` and `./kustomize/base/`.\n3. Runs `git tag` and pushes a new branch (e.g., `release/v0.3.5`) with the changes to `./release/kubernetes-manifests.yaml`.\n\nYou can then browse the [Container Registry repository](https://pantheon.corp.google.com/gcr/images/google-samples/global/microservices-demo?project=google-samples) to make sure a Docker image was created for each microservice (with the new version tag).\n\n## Create the PR\n\nNow that the release branch has been created, you can find it in the [list of branches](https://github.com/GoogleCloudPlatform/microservices-demo/branches) and create a pull request targeting `main` (the default branch).\n\nThis process is going to trigger multiple CI checks as well as stage the release onto a temporary cluster. Once the PR has been approved and all checks are successfully passing, you can then merge the branch. Make sure to include the release draft (see next section) in the pull-request description for reviewers to see.\n\nOnce reviewed and you're ready to merge, make sure to not delete the release branch or the tags during that process.\n\n## Add notes to the release\n\nOnce the PR has been fully merged, you are ready to create a new release for the newly created [tag](https://github.com/GoogleCloudPlatform/microservices-demo/tags).\n- Click the breadcrumbs on the row of the latest tag that was created in the [tags](https://github.com/GoogleCloudPlatform/microservices-demo/tags) page\n- Select the `Create release` option\n\nThe release notes should contain a brief description of the changes since the previous release (like bug fixed and new features). For inspiration, you can look at the list of [releases](https://github.com/GoogleCloudPlatform/microservices-demo/releases).\n\n> ***Note:*** No assets need to be uploaded. They are picked up automatically from the tagged revision\n\n## Deploy on the production environment\n\nOnce the release notes are published, you should then replace the version of the production environment to the newly published version.\n\n1. Connect to the [online-boutique-release GKE cluster](https://pantheon.corp.google.com/kubernetes/clusters/details/us-central1-c/online-boutique-release/details?project=online-boutique-ci):\n\n ```sh\n gcloud container clusters get-credentials online-boutique-release \\\n --zone us-central1-c --project online-boutique-ci\n ```\n\n2. Deploy `release/kubernetes-manifests.yaml` to it:\n\n ```sh\n kubectl apply -f ./release/kubernetes-manifests.yaml\n ```\n\n3. Remove unnecessary objects:\n\n ```sh\n kubectl delete service frontend-external\n kubectl delete deployment loadgenerator\n ```\n\n3. Make sure [cymbal-shops.retail.cymbal.dev](https://cymbal-shops.retail.cymbal.dev) works.\n\n## Update major tags\n\n1. Update the relevant major tag (for example, `v1`):\n\n ```sh\n export MAJOR_TAG=v0 # Edit this as needed (to v1/v2/v3/etc)\n git checkout release/${TAG}\n git pull\n git push --delete origin ${MAJOR_TAG} # Delete the remote tag (if it exists)\n git tag --delete ${MAJOR_TAG} # Delete the local tag (if it exists)\n git tag -a ${MAJOR_TAG} -m \"Updating ${MAJOR_TAG} to its most recent release: ${TAG}\"\n git push origin ${MAJOR_TAG} # Push the new tag to origin\n ```\n\n## Announce the new release internally\n\nOnce the new release is out, you can now announce it via [g/online-boutique-announce](https://groups.google.com/a/google.com/g/online-boutique-announce).\n" }, { "path": "docs/releasing/license_header.txt", "content": "# Copyright 2025 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n" }, { "path": "docs/releasing/make-docker-images.sh", "content": "#!/usr/bin/env bash\n\n# Copyright 2019 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\n# Builds and pushes docker image for each demo microservice.\n\nset -euo pipefail\nSCRIPT_DIR=\"$( cd \"$( dirname \"${BASH_SOURCE[0]}\" )\" && pwd )\"\nREPO_ROOT=$SCRIPT_DIR/../..\n\nlog() { echo \"$1\" >&2;

Each variations is designed as a [**Kustomize component**](https://github.com/kubernetes-sigs/kustomize/blob/master/examples/components.md), so multiple variations can be composed together in the deployment.\n\n## What is Kustomize?\n\nKustomize is a Kubernetes configuration management tool that allows users to customize their manifest configurations without duplication. Its commands are built into `kubectl` as `apply -k`. More information on Kustomize can be found on the [official Kustomize website](https://kustomize.io/).\n\n## Prerequisites\n\nOptionally, [install the `kustomize` binary](https://kubectl.docs.kubernetes.io/installation/) to avoid manually editing a `kustomization.yaml` file. Online Boutique's instructions will often use `kustomize edit` (like `kustomize edit add component components/some-component`), but you can skip these commands and instead add components manually to the [`/kustomize/kustomization.yaml` file](/kustomize/kustomization.yaml).\n\nYou need to have a Kubernetes cluster where you will deploy the Online Boutique's Kubernetes manifests. To set up a GKE (Google Kubernetes Engine) cluster, you can follow the instruction in the [root `/README.md`](/).\n\n## Deploy Online Boutique with Kustomize\n\n1. From the root folder of this repository, navigate to the `kustomize/` directory.\n\n ```bash\n cd kustomize/\n ```\n\n1. See what the default Kustomize configuration defined by `kustomize/kustomization.yaml` will generate (without actually deploying them yet).\n\n ```bash\n kubectl kustomize .\n ```\n\n1. Apply the default Kustomize configuration (`kustomize/kustomization.yaml`).\n\n ```bash\n kubectl apply -k .\n ```\n\n1. Wait for all Pods to show `STATUS` of `Running`.\n\n ```bash\n kubectl get pods\n ```\n\n The output should be similar to the following:\n\n ```terminal\n NAME READY STATUS RESTARTS AGE\n adservice-76bdd69666-ckc5j 1/1 Running 0 2m58s\n cartservice-66d497c6b7-dp5jr 1/1 Running 0 2m59s\n checkoutservice-666c784bd6-4jd22 1/1 Running 0 3m1s\n currencyservice-5d5d496984-4jmd7 1/1 Running 0 2m59s\n emailservice-667457d9d6-75jcq 1/1 Running 0 3m2s\n frontend-6b8d69b9fb-wjqdg 1/1 Running 0 3m1s\n loadgenerator-665b5cd444-gwqdq 1/1 Running 0 3m\n paymentservice-68596d6dd6-bf6bv 1/1 Running 0 3m\n productcatalogservice-557d474574-888kr 1/1 Running 0 3m\n recommendationservice-69c56b74d4-7z8r5 1/1 Running 0 3m1s\n shippingservice-6ccc89f8fd-v686r 1/1 Running 0 2m58s\n ```\n\n _Note: It may take 2-3 minutes before the changes are reflected on the deployment._\n\n1. Access the web frontend in a browser using the frontend's `EXTERNAL_IP`.\n\n ```bash\n kubectl get service frontend-external | awk '{print $4}'\n ```\n\n Note: you may see `` while GCP provisions the load balancer. If this happens, wait a few minutes and re-run the command.\n\n## Deploy Online Boutique variations with Kustomize\n\nHere is the list of the variations available as Kustomize components that you could leverage:\n\n- [**Change to the Cymbal Shops Branding**](components/cymbal-branding)\n - Changes all Online Boutique-related branding to Google Cloud's fictitious company — Cymbal Shops. The code adds/enables an environment variable `CYMBAL_BRANDING` in the `frontend` service.\n- [**Integrate with Google Cloud Operations**](components/google-cloud-operations)\n - Enables Monitoring (Stats), Tracing, and Profiler for various services within Online Boutique. The code adds the appropriare environment variables (`ENABLE_STATS`, `ENABLE_TRACING`, `DISABLE_PROFILER`) for each YAML config file.\n- [**Integrate with Memorystore (Redis)**](components/memorystore)\n - The default Online Boutique deployment uses the in-cluster `redis` database for storing the contents of its shopping cart. The Memorystore deployment variation overrides the default database with its own Memorystore (Redis) database. These changes directly affect `cartservice`.\n- [**Integrate with Spanner**](components/spanner)\n - The default Online Boutique deployment uses the in-cluster `redis` database for storing the contents of its shopping cart. The Spanner deployment variation overrides the default database with its own Spanner database. These changes directly affect `cartservice`.\n- [**Integrate with AlloyDB**](components/alloydb)\n - The default Online Boutique deployment uses the in-cluster `redis` database for storing the contents of its shopping cart. The AlloyDB deployment variation overrides the default database with its own AlloyDB database.\nThese changes directly affect `cartservice`.\n- [**Secure with Network Policies**](components/network-policies)\n - Deploy fine granular `NetworkPolicies` for Online Boutique.\n- [**Update the registry name of the container images**](components/container-images-registry)\n- [**Update the image tag of the container images**](components/container-images-tag)\n- [**Add an image tag suffix to the container images**](components/container-images-tag-suffix)\n- [**Do not expose the `frontend` publicly**](components/non-public-frontend)\n- [**Set the `frontend` to manage only one single shared session**](components/single-shared-session)\n- [**Configure `Istio` service mesh resources**](components/service-mesh-istio)\n\n### Select variations\n\nTo customize Online Boutique with its variations, you need to update the default `kustomize/kustomization.yaml` file. You could do that manually, use `sed`, or use the `kustomize edit` command like illustrated below.\n\n#### Use `kustomize edit` to select variations\n\nHere is an example with the [**Cymbal Shops Branding**](components/cymbal-branding) variation, from the `kustomize/` folder, run the command below:\n\n```bash\nkustomize edit add component components/cymbal-branding\n```\n\nYou could now combine it with other variations, like for example with the [**Google Cloud Operations**](components/google-cloud-operations) variation:\n\n```bash\nkustomize edit add component components/google-cloud-operations\n```\n\n### Deploy selected variations\n\nLike explained earlier, you can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\nSo for example, the associated `kustomization.yaml` could look like:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/cymbal-branding\n- components/google-cloud-operations\n```\n\n### Use remote Kustomize targets\n\nKustomize allows you to reference public remote resources so the `kustomization.yaml` could look like:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- github.com/GoogleCloudPlatform/microservices-demo/kustomize/base\ncomponents:\n- github.com/GoogleCloudPlatform/microservices-demo/kustomize/components/cymbal-branding\n- github.com/GoogleCloudPlatform/microservices-demo/kustomize/components/google-cloud-operations\n```\n\nLearn more about [Kustomize remote targets](https://github.com/kubernetes-sigs/kustomize/blob/master/examples/remoteBuild.md).\n" }, { "path": "kustomize/base/adservice.yaml", "content": "# Copyright 2018 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\napiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: adservice\n labels:\n app: adservice\nspec:\n selector:\n matchLabels:\n app: adservice\n template:\n metadata:\n labels:\n app: adservice\n spec:\n serviceAccountName: adservice\n terminationGracePeriodSeconds: 5\n securityContext:\n fsGroup: 1000\n runAsGroup: 1000\n runAsNonRoot: true\n runAsUser: 1000\n containers:\n -

The Cloud Shell doesn't work because of transitive VPC peering not working.\n\n## Provision an AlloyDB database and the supporting infrastructure\n\nEnvironmental variables needed for setup. These should be set in a .bashrc or similar as some of the variables are used in the application itself. Default values are supplied in this readme, but any of them can be changed. Anything in <> needs to be replaced.\n\n```bash\n# PROJECT_ID should be set to the project ID that was created to hold the demo\nPROJECT_ID=\n\n#Pick a region near you that also has AlloyDB available.

The command to set this in the shell is included below, but it would also be a good idea to run the command, and manually set the IP address in the .bashrc\nALLOYDB_PRIMARY_IP=\nALLOYDB_READ_IP=\n\nALLOYDB_DATABASE_NAME=carts\nALLOYDB_TABLE_NAME=cart_items\nALLOYDB_USER_GSA_NAME=alloydb-user-sa\nALLOYDB_USER_GSA_ID=${ALLOYDB_USER_GSA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com\nCARTSERVICE_KSA_NAME=cartservice\nALLOYDB_SECRET_NAME=alloydb-secret\n\n# PGPASSWORD needs to be set in order to run the psql from the CLI easily. The value for this\n# needs to be set behind the Secret mentioned above\nPGPASSWORD=\n```\n\nTo provision an AlloyDB instance you can follow the following instructions:\n```bash\ngcloud services enable alloydb.googleapis.com\ngcloud services enable servicenetworking.googleapis.com\ngcloud services enable secretmanager.googleapis.com\n\n# Set our DB credentials behind the secret. Replace with whatever you want\n# to use as the credentials for the database.

INDEX cartItemsByUserId ON ${ALLOYDB_TABLE_NAME}(userId)\"\n```\n\n_Note: It can take more than 20 minutes for the AlloyDB instances to be created._\n\n## Grant the `cartservice`'s service account access to the AlloyDB database\n\n**Important note:** Your GKE cluster should have [Workload Identity enabled](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity#enable).\n\nAs a good practice, let's create a dedicated least privilege Google Service Account to allow the `cartservice` to communicate with the AlloyDB database and grab the database password from the Secret manager.:\n```bash\ngcloud iam service-accounts create ${ALLOYDB_USER_GSA_NAME} \\\n --display-name=${ALLOYDB_USER_GSA_NAME}\n\ngcloud projects add-iam-policy-binding ${PROJECT_ID} --member=serviceAccount:${ALLOYDB_USER_GSA_ID} --role=roles/alloydb.client\ngcloud projects add-iam-policy-binding ${PROJECT_ID} --member=serviceAccount:${ALLOYDB_USER_GSA_ID} --role=roles/secretmanager.secretAccessor\n\ngcloud iam service-accounts add-iam-policy-binding ${ALLOYDB_USER_GSA_ID} \\\n --member \"serviceAccount:${PROJECT_ID}.svc.id.goog[default/${CARTSERVICE_KSA_NAME}]\" \\\n --role roles/iam.workloadIdentityUser\n```\n\n## Deploy Online Boutique connected to an AlloyDB database\n\nTo automate the deployment of Online Boutique integrated with AlloyDB you can leverage the following variation with [Kustomize](../..).\n\nFrom the `kustomize/` folder at the root level of this repository, execute these commands:\n```bash\nkustomize edit add component components/alloydb\n```\n_**Note:** this Kustomize component will also remove the `redis-cart` `Deployment` and `Service` not used anymore._\n\nThis will update the `kustomize/kustomization.yaml` file which could be similar to:\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/alloydb\n```\n\nUpdate current Kustomize manifest to target this AlloyDB database.\n```bash\nsed -i \"s/PROJECT_ID_VAL/${PROJECT_ID}/g\" components/alloydb/kustomization.yaml\nsed -i \"s/ALLOYDB_PRIMARY_IP_VAL/${ALLOYDB_PRIMARY_IP}/g\" components/alloydb/kustomization.yaml\nsed -i \"s/ALLOYDB_USER_GSA_ID/${ALLOYDB_USER_GSA_ID}/g\" components/alloydb/kustomization.yaml\nsed -i \"s/ALLOYDB_DATABASE_NAME_VAL/${ALLOYDB_DATABASE_NAME}/g\" components/alloydb/kustomization.yaml\nsed -i \"s/ALLOYDB_TABLE_NAME_VAL/${ALLOYDB_TABLE_NAME}/g\" components/alloydb/kustomization.yaml\nsed -i \"s/ALLOYDB_SECRET_NAME_VAL/${ALLOYDB_SECRET_NAME}/g\" components/alloydb/kustomization.yaml\n```\n\nYou can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\n## Extra cleanup steps\n```bash\ngcloud compute addresses delete ${ALLOYDB_SERVICE_NAME} --global\n\n# Force takes care of cleaning up the instances inside the cluster automatically\ngcloud alloydb clusters delete ${ALLOYDB_CLUSTER_NAME} --force --region ${REGION}\n\ngcloud iam service-accounts delete ${ALLOYDB_USER_GSA_ID}\n\ngcloud secrets delete ${ALLOYDB_SECRET_NAME}\n```\n" }, { "path":

This includes Monitoring (Stats), Tracing, and Profiler. This means that even if you're running this app on [GKE](https://cloud.google.com/kubernetes-engine), traces (for example) will not be exported to [Google Cloud Trace](https://cloud.google.com/trace).\n\nIf you want to re-enable Google Cloud Operations instrumentation, the easiest way is to enable the included kustomize module, which enables traces, metrics, and adds a deployment of the [Open Telemetry Collector](https://opentelemetry.io/docs/collector/) to gather the traces and metrics and forward them to the appropriate Google Cloud backend.\n\nFrom the `kustomize/` folder at the root level of this repository, execute this command:\n\n```bash\nkustomize edit add component components/google-cloud-operations\n```\n\nThis will update the `kustomize/kustomization.yaml` file which could be similar to:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/google-cloud-operations\n```\n\nYou can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\nYou will also need to make sure that you have the associated Google APIs enabled in your Google Cloud project:\n\n```bash\nPROJECT_ID=\ngcloud services enable \\\n monitoring.googleapis.com \\\n cloudtrace.googleapis.com \\\n cloudprofiler.googleapis.com \\\n --project ${PROJECT_ID}\n```\n\nIn addition to that, you will need to grant the following IAM roles associated to your Google Service Account (GSA):\n\n```bash\nPROJECT_ID=\nGSA_NAME=\n\ngcloud projects add-iam-policy-binding ${PROJECT_ID} \\\n --member \"serviceAccount:${GSA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role roles/cloudtrace.agent\n\ngcloud projects add-iam-policy-binding ${PROJECT_ID} \\\n --member \"serviceAccount:${GSA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role roles/monitoring.metricWriter\n \ngcloud projects add-iam-policy-binding ${PROJECT_ID} \\\n --member \"serviceAccount:${GSA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role roles/cloudprofiler.agent\n```\n\n**Note**\nCurrently only trace is supported. Support for metrics, and more is coming soon.\n\n## Changes\n\nWhen enabling this kustomize module, most services will be patched with a configuration similar to the following:\n\n```yaml\napiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: productcatalogservice\nspec:\n template:\n spec:\n containers:\n - name: server\n env:\n - name: COLLECTOR_SERVICE_ADDR\n value: \"opentelemetrycollector:4317\"\n - name: ENABLE_STATS\n value: \"1\"\n - name: ENABLE_TRACING\n value: \"1\"\n```\n\nThis patch sets environment variables to enable export of stats and tracing, as well as a variable to tell the service how to reach the new collector deployment.\n\n## OpenTelemetry Collector\n\nCurrently, this component adds a single collector service which collects traces and metrics from individual services and forwards them to the appropriate Google Cloud backend.\n\n![Collector Architecture Diagram](collector-model.png)\n\nIf you wish to experiment with different backends, you can modify the appropriate lines in [otel-collector.yaml](otel-collector.yaml) to export traces or metrics to a different backend. See the [OpenTelemetry docs](https://opentelemetry.io/docs/collector/configuration/) for more details.\n\n## Workload Identity\n\nIf you are running this sample on GKE, your GKE cluster may be configured to use [Workload Identity](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity) to manage access to Google Cloud APIs (like Cloud Trace). If this is the case, you may not see traces properly exported, or may see an error message like `failed to export to Google Cloud Trace: rpc error: code = PermissionDenied desc = The caller does not have permission` logged by your `opentelemetrycollector` Pod(s). In order to export traces with such a setup, you need to associate the Kubernetes [ServiceAccount](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/) (`default/default`) with your [default compute service account](https://cloud.google.com/compute/docs/access/service-accounts#default_service_account) on Google Cloud (or a custom Google Cloud service account you may create for this purpose).\n\n* To get the email address associated with your Google service account, check in the IAM section of the Cloud Console. Or run the following command in your terminal:\n\n```bash\ngcloud iam service-accounts list\n```\n\n* Then, allow the Kubernetes service account to act as your Google service account with the following command (using your own `PROJECT_ID` and the `GSA_EMAIL` you found in the previous step):\n\n```bash\ngcloud iam service-accounts add-iam-policy-binding ${GSA_EMAIL} \\\n --role roles/iam.workloadIdentityUser \\\n --member \"serviceAccount:${PROJECT_ID}.svc.id.goog[default/default]\"\n```\n\n* Annotate your Kubernetes service account (`default/default` for the `default` namespace) to use the Google IAM service account:\n\n```bash\nkubectl annotate serviceaccount default \\\n iam.gke.io/gcp-service-account=${GSA_EMAIL}\n```\n\n* Finally, restart your `opentelemetrycollector` deployment to reflect the new settings:\n\n```bash\nkubectl rollout restart deployment opentelemetrycollector\n```\n\nWhen the new Pod rolls out, you should start to see traces appear in the cloud console.\n" }, { "path": "kustomize/components/google-cloud-operations/kustomization.yaml", "content": "# Copyright 2022 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\napiVersion: kustomize.config.k8s.io/v1alpha1\nkind: Component\nresources:\n -

Using a database outside your GKE cluster could bring more resiliency and more security with a managed service like Google Cloud Memorystore (Redis).\n\n![Architecture diagram with Memorystore](/docs/img/memorystore.png)\n\n## Provision a Memorystore (Redis) instance\n\nImportant notes:\n\n- You can connect to a Memorystore (Redis) instance from GKE clusters that are in the same region and use the same network as your instance.\n- You cannot connect to a Memorystore (Redis) instance from a GKE cluster without VPC-native/IP aliasing enabled.\n\nTo provision a Memorystore (Redis) instance you can follow the following instructions:\n\n```bash\nZONE=\"\"\nREGION=\"\"\n\ngcloud services enable redis.googleapis.com\n\ngcloud redis instances create redis-cart \\\n --size=1 \\\n --region=${REGION} \\\n --zone=${ZONE} \\\n --redis-version=redis_7_0\n```\n\n_Note: You can also find in this repository the Terraform script to provision the Memorystore (Redis) instance alongside the GKE cluster, more information [here](/terraform)._\n\n## Deploy Online Boutique connected to a Memorystore (Redis) instance\n\nTo automate the deployment of Online Boutique integrated with Memorystore (Redis) you can leverage the following variation with [Kustomize](../..).\n\nFrom the `kustomize/` folder at the root level of this repository, execute this command:\n\n```bash\nkustomize edit add component components/memorystore\n```\n\n_Note: this Kustomize component will also remove the `redis-cart` `Deployment` and `Service` not used anymore._\n\nThis will update the `kustomize/kustomization.yaml` file which could be similar to:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/memorystore\n```\n\nUpdate current Kustomize manifest to target this Memorystore (Redis) instance.\n\n```bash\nREDIS_IP=$(gcloud redis instances describe redis-cart --region=${REGION} --format='get(host)')\nREDIS_PORT=$(gcloud redis instances describe redis-cart --region=${REGION} --format='get(port)')\nsed -i \"s/REDIS_CONNECTION_STRING/${REDIS_IP}:${REDIS_PORT}/g\" components/memorystore/kustomization.yaml\n```\n\nYou can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\n## Resources\n\n- [Connecting to a Redis instance from a Google Kubernetes Engine cluster](https://cloud.google.com/memorystore/docs/redis/connect-redis-instance-gke)\n- [Seamlessly encrypt traffic from any apps in your Mesh to Memorystore (Redis)](https://medium.com/google-cloud/64b71969318d)\n" }, { "path": "kustomize/components/memorystore/kustomization.yaml", "content": "# Copyright 2022 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\napiVersion: kustomize.config.k8s.io/v1alpha1\nkind: Component\npatches:\n# cartservice - replace REDIS_ADDR to target new Memorystore (redis) instance\n- patch: |-\n apiVersion: apps/v1\n kind: Deployment\n metadata:\n name: cartservice\n spec:\n template:\n spec:\n containers:\n - name: server\n env:\n - name: REDIS_ADDR\n value: \"REDIS_CONNECTION_STRING\"\n# redis - remove the redis-cart Deployment\n- patch: |-\n apiVersion: apps/v1\n kind: Deployment\n metadata:\n name: redis-cart\n $patch: delete\n# redis - remove the redis-cart Service\n- patch: |-\n apiVersion: v1\n kind: Service\n metadata:\n name: redis-cart\n $patch: delete\n" }, { "path": "kustomize/components/network-policies/README.md", "content": "# Secure Online Boutique with Network Policies\n\nYou can use [Network Policies](https://kubernetes.io/docs/concepts/services-networking/network-policies/) enforcement to control the communication between your cluster's Pods and Services.\n\nTo use `NetworkPolicies` in Google Kubernetes Engine (GKE), you will need a GKE cluster with network policy enforcement enabled, the recommended approach is to use [GKE Dataplane V2](https://cloud.google.com/kubernetes-engine/docs/how-to/dataplane-v2).\n\nTo use `NetworkPolicies` on a local cluster such as [minikube](https://minikube.sigs.k8s.io/docs/start/), you will need to use an alternative CNI that supports `NetworkPolicies` like [Calico](https://projectcalico.docs.tigera.io/getting-started/kubernetes/minikube). To run a minikube cluster with Calico, run `minikube start --cni=calico`. By design, the minikube default CNI [Kindnet](https://github.com/aojea/kindnet) does not support it. \n\n## Deploy Online Boutique with `NetworkPolicies` via Kustomize\n\nTo automate the deployment of Online Boutique integrated with fine granular `NetworkPolicies` (one per `Deployment`), you can leverage the following variation with [Kustomize](../..).\n\nFrom the `kustomize/` folder at the root level of this repository, execute this command:\n\n```bash\nkustomize edit add component components/network-policies\n```\n\nThis will update the `kustomize/kustomization.yaml` file which could be similar to:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/network-policies\n```\n\nYou can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\nOnce deployed, you can verify that the `NetworkPolicies` are successfully deployed:\n\n```bash\nkubectl get networkpolicy\n```\n\nThe output could be similar to:\n\n```output\nNAME POD-SELECTOR AGE\nadservice app=adservice 2m58s\ncartservice app=cartservice 2m58s\ncheckoutservice app=checkoutservice 2m58s\ncurrencyservice app=currencyservice 2m58s\ndeny-all 2m58s\nemailservice app=emailservice 2m58s\nfrontend app=frontend 2m58s\nloadgenerator app=loadgenerator 2m58s\npaymentservice app=paymentservice 2m58s\nproductcatalogservice app=productcatalogservice 2m58s\nrecommendationservice app=recommendationservice 2m58s\nredis-cart app=redis-cart 2m58s\nshippingservice app=shippingservice 2m58s\n```\n\n_Note: `Egress` is wide open in these `NetworkPolicies` . In our case, we do this is on purpose because there are multiple egress destinations to take into consideration like the Kubernetes DNS, Istio control plane (`istiod`), Cloud Trace API, Cloud Profiler API, etc._\n\n## Related Resources\n\n- [GKE Dataplane V2 announcement](https://cloud.google.com/blog/products/containers-kubernetes/bringing-ebpf-and-cilium-to-google-kubernetes-engine)\n- [Kubernetes Network Policies](https://kubernetes.io/docs/concepts/services-networking/network-policies/)\n- [Kubernetes Network Policy Recipes](https://github.com/ahmetb/kubernetes-network-policy-recipes)\n- [Network policy logging](https://cloud.google.com/kubernetes-engine/docs/how-to/network-policy-logging)\n" }, { "path": "kustomize/components/network-policies/kustomization.yaml", "content": "# Copyright 2022 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\napiVersion: kustomize.config.k8s.io/v1alpha1\nkind: Component\nresources:\n- network-policy-deny-all.yaml\n- network-policy-adservice.yaml\n- network-policy-cartservice.yaml\n- network-policy-checkoutservice.yaml\n- network-policy-currencyservice.yaml\n- network-policy-emailservice.yaml\n- network-policy-frontend.yaml\n- network-policy-loadgenerator.yaml\n- network-policy-paymentservice.yaml\n- network-policy-productcatalogservice.yaml\n- network-policy-recommendationservice.yaml\n- network-policy-redis.yaml\n- network-policy-shippingservice.yaml\n" }, { "path": "kustomize/components/network-policies/network-policy-adservice.yaml", "content": "# Copyright 2022 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\napiVersion: networking.k8s.io/v1\nkind: NetworkPolicy\nmetadata:\n name: adservice\nspec:\n podSelector:\n matchLabels:\n app: adservice\n policyTypes:\n -

You can then label individual namespaces for sidecar injection and configure an Istio gateway to replace the frontend-external load balancer.\n\n# Setup\n\nThe following CLI tools needs to be installed and in the PATH:\n\n- `gcloud`\n- `kubectl`\n- `kustomize`\n- `istioctl` (optional)\n\n1. Set-up some default environment variables.\n\n ```sh\n PROJECT_ID=\"\"\n REGION=\" 9555/TCP 49s\n service/cartservice ClusterIP 10.68.184.25 7070/TCP 49s\n service/checkoutservice ClusterIP 10.68.177.213 5050/TCP 49s\n service/currencyservice ClusterIP 10.68.249.87 7000/TCP 49s\n service/emailservice ClusterIP 10.68.205.123 5000/TCP 49s\n service/frontend ClusterIP 10.68.94.203 80/TCP 48s\n service/istio-gateway-istio LoadBalancer 10.68.147.158 35.247.123.146 15021:30376/TCP,80:30332/TCP 45s\n service/kubernetes ClusterIP 10.68.0.1 443/TCP 65m\n service/paymentservice ClusterIP 10.68.114.19 50051/TCP 48s\n service/productcatalogservice ClusterIP 10.68.240.153 3550/TCP 48s\n service/recommendationservice ClusterIP 10.68.117.97 8080/TCP 48s\n service/redis-cart ClusterIP 10.68.189.126 6379/TCP 48s\n service/shippingservice ClusterIP 10.68.221.62 50051/TCP 48s\n ```\n\n1. Find the external IP address of your Istio gateway.\n\n ```sh\n INGRESS_HOST=\"$(kubectl get gateway istio-gateway \\\n -o jsonpath='{.status.addresses[*].value}')\"\n ```\n\n1.

Set some environment variables.\n ```sh\n export PROJECT_ID=\n export PROJECT_NUMBER=\n export PGPASSWORD=\n ```\n\n **Note**: The project ID and project number of your Google Cloud project can be found in the Console. The PostgreSQL password can be set to anything you want, but make sure to note it down.\n\n1. Change your default Google Cloud project.\n ```sh\n gcloud auth login\n gcloud config set project $PROJECT_ID\n ```\n\n1. Enable the Google Kubernetes Engine (GKE) and Artifact Registry (AR) APIs.\n ```sh\n gcloud services enable container.googleapis.com\n gcloud services enable artifactregistry.googleapis.com\n ```\n\n1. Create a GKE Autopilot cluster. This may take a few minutes.\n ```sh\n gcloud container clusters create-auto cymbal-shops \\\n --region=us-central1\n ```\n\n1. Change your Kubernetes context to your newly created GKE cluster.\n ```sh\n gcloud container clusters get-credentials cymbal-shops \\\n --region us-central1\n ```\n\n1. Create an Artifact Registry container image repository.\n ```sh\n gcloud artifacts repositories create images \\\n --repository-format=docker \\\n --location=us-central1\n ```\n\n1. Clone the `microservices-demo` repository locally.\n ```sh\n git clone https://github.com/GoogleCloudPlatform/microservices-demo \\\n && cd microservices-demo/\n ```\n\n1. Run script #1. If it asks about policy bindings, select the option `None`. This may take a few minutes.\n ```sh\n ./kustomize/components/shopping-assistant/scripts/1_deploy_alloydb_infra.sh\n ```\n\n **Note**: If you are on macOS and use a non-GNU version of `sed`, you may have to tweak the script to use `gsed` instead.\n\n1. Create a Linux VM in Compute Engine (GCE).\n ```sh\n gcloud compute instances create gce-linux \\\n --zone=us-central1-a \\\n --machine-type=e2-micro \\\n --image-family=debian-12 \\\n --image-project=debian-cloud \n ```\n\n1. SSH into the VM. From here until we exit, all steps happen in the VM.\n ```sh\n gcloud compute ssh gce-linux \\\n --zone \"us-central1-a\"\n ```\n\n1. Install the Postgres client and set your default Google Cloud project.\n ```sh\n sudo apt-get install -y postgresql-client\n gcloud auth login\n gcloud config set project \n ```\n\n1. Copy script #2, the python script, and the products.json to the VM. Make sure the scripts are executable.\n ```sh\n nano 2_create_populate_alloydb_tables.sh # paste content\n nano generate_sql_from_products.py # paste content\n nano products.json # paste content\n chmod +x 2_create_populate_alloydb_tables.sh\n chmod +x generate_sql_from_products.py\n ```\n\n **Note:** You can find the files at the following places:\n - `kustomize/components/shopping-assistant/scripts/2_create_populate_alloydb_tables.sh`\n - `kustomize/components/shopping-assistant/scripts/generate_sql_from_products.py`\n - `src/productcatalogservice/products.json`\n\n1. Run script #2 in the VM. If it asks for a postgres password, it should be the same that you set in script #1 earlier. This may take a few minutes.\n ```sh\n ./2_create_populate_alloydb_tables.sh\n ```\n\n1. Exit SSH.\n ```sh\n exit\n ```\n\n1. Create an API key in the [Credentials page](https://pantheon.corp.google.com/apis/credentials) with permissions for \"Generative Language API\", and make note of the secret key.\n\n1. Replace the Google API key placeholder in the shoppingassistant service.\n ```sh\n export GOOGLE_API_KEY=\n sed -i \"s/GOOGLE_API_KEY_VAL/${GOOGLE_API_KEY}/g\" kustomize/components/shopping-assistant/shoppingassistantservice.yaml\n ```\n\n1. Edit the root Kustomize file to enable the `alloydb` and `shopping-assistant` components.\n ```sh\n nano kubernetes-manifests/kustomization.yaml # make the modifications below\n ```\n \n ```yaml\n # ...head of the file\n components: # remove this comment\n # - ../kustomize/components/cymbal-branding\n # - ../kustomize/components/google-cloud-operations\n # - ../kustomize/components/memorystore\n # - ../kustomize/components/network-policies\n - ../kustomize/components/alloydb # remove this comment\n - ../kustomize/components/shopping-assistant # remove this comment\n # - ../kustomize/components/spanner\n # - ../kustomize/components/container-images-tag\n # - ../kustomize/components/container-images-tag-suffix\n # - ../kustomize/components/container-images-registry\n ```\n\n1. Deploy to the GKE cluster.\n ```sh\n skaffold run --default-repo=us-central1-docker.pkg.dev/$PROJECT_ID/images\n ```\n\n1. Wait for all the pods to be up and running. You can then find the external IP and navigate to it.\n ```sh\n kubectl get pods\n kubectl get services\n ```\n" }, { "path": "kustomize/components/shopping-assistant/kustomization.yaml", "content":

sessions.\nThis is useful for multi-cluster environments.\n\n## Deploy Online Boutique to generate a single shared session\n\nTo automate the deployment of Online Boutique to manage a single shared

data in an in-cluster Redis database.\nUsing a fully managed database service outside your GKE cluster (such as [Google Cloud Spanner](https://cloud.google.com/spanner)) could bring more resiliency and more security.\n\n## Provision a Spanner database\n\nTo provision a Spanner instance you can follow the following instructions:\n\n```bash\ngcloud services enable spanner.googleapis.com\n\nSPANNER_REGION_CONFIG=\"\" # e.g. \"regional-us-east5\"\nSPANNER_INSTANCE_NAME=onlineboutique\n\ngcloud spanner instances create ${SPANNER_INSTANCE_NAME} \\\n --description=\"online boutique shopping cart\" \\\n --config ${SPANNER_REGION_CONFIG} \\\n --instance-type free-instance\n```\n\n_Note: With latest version of `gcloud` we are creating a free Spanner instance._\n\nTo provision a Spanner database you can follow the following instructions:\n\n```bash\nSPANNER_DATABASE_NAME=carts\n\ngcloud spanner databases create ${SPANNER_DATABASE_NAME} \\\n --instance ${SPANNER_INSTANCE_NAME} \\\n --database-dialect GOOGLE_STANDARD_SQL \\\n --ddl \"CREATE TABLE CartItems (userId STRING(1024), productId STRING(1024), quantity INT64) PRIMARY KEY (userId, productId); CREATE INDEX CartItemsByUserId ON CartItems(userId);\"\n```\n\n## Grant the `cartservice`'s service account access to the Spanner database\n\n**Important note:** Your GKE cluster should have [Workload Identity enabled](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity#enable).\n\nAs a good practice, let's create a dedicated least privilege Google Service Account to allow the `cartservice` to communicate with the Spanner database:\n\n```bash\nPROJECT_ID=\nSPANNER_DB_USER_GSA_NAME=spanner-db-user-sa\nSPANNER_DB_USER_GSA_ID=${SPANNER_DB_USER_GSA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com\nONLINEBOUTIQUE_NAMESPACE=default\nCARTSERVICE_KSA_NAME=cartservice\n\ngcloud iam service-accounts create ${SPANNER_DB_USER_GSA_NAME} \\\n --display-name=${SPANNER_DB_USER_GSA_NAME}\n\ngcloud spanner databases add-iam-policy-binding ${SPANNER_DATABASE_NAME} \\\n --member \"serviceAccount:${SPANNER_DB_USER_GSA_ID}\" \\\n --role roles/spanner.databaseUser\n\ngcloud iam service-accounts add-iam-policy-binding ${SPANNER_DB_USER_GSA_ID} \\\n --member \"serviceAccount:${PROJECT_ID}.svc.id.goog[${ONLINEBOUTIQUE_NAMESPACE}/${CARTSERVICE_KSA_NAME}]\" \\\n --role roles/iam.workloadIdentityUser\n```\n\n## Deploy Online Boutique connected to a Spanner database\n\nTo automate the deployment of Online Boutique integrated with Spanner you can leverage the following variation with [Kustomize](../..).\n\nFrom the `kustomize/` folder at the root level of this repository, execute these commands:\n\n```bash\nkustomize edit add component components/spanner\n```\n\n_Note: this Kustomize component will also remove the `redis-cart` `Deployment` and `Service` not used anymore._\n\nThis will update the `kustomize/kustomization.yaml` file which could be similar to:\n\n```yaml\napiVersion: kustomize.config.k8s.io/v1beta1\nkind: Kustomization\nresources:\n- base\ncomponents:\n- components/spanner\n```\n\nUpdate current Kustomize manifest to target this Spanner database.\n\n```bash\nsed -i \"s/SPANNER_PROJECT/${PROJECT_ID}/g\" components/spanner/kustomization.yaml\nsed -i \"s/SPANNER_INSTANCE/${SPANNER_INSTANCE_NAME}/g\" components/spanner/kustomization.yaml\nsed -i \"s/SPANNER_DATABASE/${SPANNER_DATABASE_NAME}/g\" components/spanner/kustomization.yaml\nsed -i \"s/SPANNER_DB_USER_GSA_ID/${SPANNER_DB_USER_GSA_ID}/g\" components/spanner/kustomization.yaml\n```\n\nYou can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.\n\n## Note on Spanner connection environment variables\n\nThe following environment variables will be used by the `cartservice`, if present:\n\n- `SPANNER_INSTANCE`: defaults to `onlineboutique`, unless specified.\n- `SPANNER_DATABASE`: defaults to `carts`, unless specified.\n- `SPANNER_CONNECTION_STRING`: defaults to `projects/${SPANNER_PROJECT}/instances/${SPANNER_INSTANCE}/databases/${SPANNER_DATABASE}`.

that is purposefully\nnot well implemented. The goal of this feature is to allow you to modify the\n`products.json` file and have the changes be picked up without having to\nrestart the service.\n\nHowever, this feature is bugged: the catalog is actually reloaded on each\nrequest, introducing a noticeable delay in the frontend. This delay will also\nshow up in profiling tools: the `parseCatalog` function will take more than 80%\nof the CPU time.\n\nYou can trigger this feature (and the delay) by sending a `USR1` signal and\nremove it (if needed) by sending a `USR2` signal:\n\n```\n# Trigger bug\nkubectl exec \\\n $(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \\\n -c server -- kill -USR1 1\n# Remove bug\nkubectl exec \\\n $(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \\\n -c server -- kill -USR2 1\n```\n\n## Latency injection\n\nThis service has an `EXTRA_LATENCY` environment variable. This will inject a sleep for the specified [time.Duration](https://golang.org/pkg/time/#ParseDuration) on every call to\nto the server.\n\nFor example, use `EXTRA_LATENCY=\"5.5s\"` to sleep for 5.5 seconds on every request.\n" }, { "path": "src/productcatalogservice/catalog_loader.go", "content": "// Copyright 2024 Google LLC\n//\n// Licensed under the Apache License, Version 2.0 (the \"License\");\n// you may not use this file except in compliance with the License.\n// You may obtain a copy of the License at\n//\n// https://www.apache.org/licenses/LICENSE-2.0\n//\n// Unless required by applicable law or agreed to in writing, software\n// distributed under the License is distributed on an \"AS IS\" BASIS,\n// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n// See the License for the specific language governing permissions and\n// limitations under the License.\n\npackage main\n\nimport (\n\t\"bytes\"\n\t\"context\"\n\t\"fmt\"\n\t\"net\"\n\t\"os\"\n\t\"strings\"\n\n\t\"cloud.google.com/go/alloydbconn\"\n\tsecretmanager \"cloud.google.com/go/secretmanager/apiv1\"\n\t\"cloud.google.com/go/secretmanager/apiv1/secretmanagerpb\"\n\tpb \"github.com/GoogleCloudPlatform/microservices-demo/src/productcatalogservice/genproto\"\n\t\"github.com/golang/protobuf/jsonpb\"\n\t\"github.com/jackc/pgx/v5/pgxpool\"\n)\n\nfunc loadCatalog(catalog *pb.ListProductsResponse) error {\n\tcatalogMutex.Lock()\n\tdefer catalogMutex.Unlock()\n\n\tif os.Getenv(\"ALLOYDB_CLUSTER_NAME\") != \"\" {\n\t\treturn loadCatalogFromAlloyDB(catalog)\n\t}\n\n\treturn loadCatalogFromLocalFile(catalog)\n}\n\nfunc loadCatalogFromLocalFile(catalog *pb.ListProductsResponse) error {\n\tlog.Info(\"loading catalog from local products.json file...\")\n\n\tcatalogJSON, err := os.ReadFile(\"products.json\")\n\tif err != nil {\n\t\tlog.Warnf(\"failed to open product catalog json file: %v\", err)\n\t\treturn err\n\t}\n\n\tif err := jsonpb.Unmarshal(bytes.NewReader(catalogJSON), catalog);

[Create a new project or use an existing project](https://cloud.google.com/resource-manager/docs/creating-managing-projects#console) on Google Cloud, and ensure [billing is enabled](https://cloud.google.com/billing/docs/how-to/verify-billing-enabled) on the project.\n\n## Deploy the sample application\n\n1. Clone the Github repository.\n\n ```bash\n git clone https://github.com/GoogleCloudPlatform/microservices-demo.git\n ```\n\n1. Move into the `terraform/` directory which contains the Terraform installation scripts.\n\n ```bash\n cd microservices-demo/terraform\n ```\n\n1. Open the `terraform.tfvars` file and replace `` with the [GCP Project ID](https://cloud.google.com/resource-manager/docs/creating-managing-projects?hl=en#identifying_projects) for the `gcp_project_id` variable.\n\n1. (Optional) If you want to provision a [Google Cloud Memorystore (Redis)](https://cloud.google.com/memorystore) instance, you can change the value of `memorystore = false` to `memorystore = true` in this `terraform.tfvars` file.\n\n1. Initialize Terraform.\n\n ```bash\n terraform init\n ```\n\n1. See what resources will be created.\n\n ```bash\n terraform plan\n ```\n\n1. Create the resources and deploy the sample.\n\n ```bash\n terraform apply\n ```\n\n 1. If there is a confirmation prompt, type `yes` and hit Enter/Return.\n\n Note: This step can take about 10 minutes. Do not interrupt the process.\n\nOnce the Terraform script has finished, you can locate the frontend's external IP address to access the sample application.\n\n- Option 1:\n\n ```bash\n kubectl get service frontend-external | awk '{print $4}'\n ```\n\n- Option 2: On Google Cloud Console, navigate to \"Kubernetes Engine\" and then \"Services & Ingress\" to locate the Endpoint associated with \"frontend-external\".\n\n## Clean up\n\nTo avoid incurring charges to your Google Cloud account for the resources used in this sample application, either delete the project that contains the resources, or keep the project and delete the individual resources.\n\nTo remove the individual resources created for by Terraform without deleting the project:\n\n1. Navigate to the `terraform/` directory.\n\n1. Set `deletion_protection` to `false` for the `google_container_cluster` resource (GKE cluster).\n\n ```bash\n # Uncomment the line: \"deletion_protection = false\"\n sed -i \"s/# deletion_protection/deletion_protection/g\" main.tf\n\n # Re-apply the Terraform to update the state\n terraform apply\n ```\n\n1. Run the following command:\n\n ```bash\n terraform destroy\n ```\n\n 1. If there is a confirmation prompt, type `yes` and hit Enter/Return.\n" }, { "path": "terraform/main.tf", "content": "# Copyright 2022 Google LLC\n#\n# Licensed under the Apache License, Version 2.0 (the \"License\");\n# you may not use this file except in compliance with the License.\n# You may obtain a copy of the License at\n#\n# http://www.apache.org/licenses/LICENSE-2.0\n#\n# Unless required by applicable law or agreed to in writing, software\n# distributed under the License is distributed on an \"AS IS\" BASIS,\n# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n# See the License for the specific language governing permissions and\n# limitations under the License.\n\n# Definition of local variables\nlocals {\n base_apis = [\n \"container.googleapis.com\",\n \"monitoring.googleapis.com\",\n \"cloudtrace.googleapis.com\",\n \"cloudprofiler.googleapis.com\"\n ]\n memorystore_apis = [\"redis.googleapis.com\"]\n cluster_name = google_container_cluster.my_cluster.name\n}\n\n# Enable Google Cloud APIs\nmodule \"enable_google_apis\" {\n source = \"terraform-google-modules/project-factory/google//modules/project_services\"\n version = \"~> 18.0\"\n\n project_id = var.gcp_project_id\n disable_services_on_destroy = false\n\n # activate_apis is the set of base_apis and the APIs required by user-configured deployment options\n activate_apis = concat(local.base_apis, var.memorystore ?
