# Contributor Guide
MicroK8s is open source ([Apache License 2.0](./LICENSE)) and actively seeks any community contributions for code, add-ons, suggestions and documentation.
Many of the features currently part of MicroK8s originated in the community, and we are very keen for that to continue. This page details a few notes,
workflows and suggestions for how to make contributions most effective and help us all build a better MicroK8s for everyone - please give them a read before
working on any contributions.
## Licensing
MicroK8s has been created under the [Apache License 2.0](./LICENSE), which will cover any contributions you may make to this project. Please familiarise
yourself with the terms of the license.
Additionally, MicroK8s uses the Harmony CLA agreement. It’s the easiest way for you to give us permission to use your contributions.
In effect, you’re giving us a licence, but you still own the copyright — so you retain the right to modify your code and use it in
other projects. Please [sign the CLA here](https://ubuntu.com/legal/contributors/agreement) before making any contributions.
## Code of conduct
MicroK8s has adopted the Ubuntu code of Conduct. You can read this in full [here](https://ubuntu.com/community/code-of-conduct).
## Contributing code
The workflow for contributing code is as follows:
1. **Create/choose an issue**: MicroK8s tracks issues at [https://github.com/canonical/microk8s/issues](https://github.com/canonical/microk8s/issues). If you
want to work on a new feature, create an issue first! This gives everyone a place to discuss scope and implementation.
2. **Create a fork of the MicroK8s repo**
3. **Make a new branch for your contribution**. Write your code there.
4. For details on how to **build and test MicroK8s**, see the [build instructions](./docs/build.md). Add new tests as needed,
and make sure the existing tests continue to pass when your changes are complete.
5. **Submit a pull request** to get changes from your branch into master. You can add "#Fixes xxx" where `xxx` is the issue number to
automatically link to the issue you chose or created earlier.
6. Someone will review your PR and may make suggestions or have comments, so **keep an eye on the PR status** in case there are changes to make
7. **Please make sure you have submitted your [CLA form](https://ubuntu.com/legal/contributors/agreement) if you are a first time contributor**.
8. Thanks!
## Documentation
Docs for MicroK8s are published online at [https://microk8s.io/docs](https://microk8s.io/docs). You can make suggestions and edit the pages themselves by joining
the Kubernetes discourse at [discuss.kubernetes.io](https://discuss.kubernetes.io/t/introduction-to-microk8s/11243) or follow the link at
the bottom of any of the pages published at [https://microk8s.io/docs](https://microk8s.io/docs)
There is a documentation page which describes how to write and edit docs, [published as part of the documentation](https://microk8s.io/docs/docs).

## The smallest, fastest Kubernetes
Single-package fully conformant lightweight Kubernetes that works on [42
flavours of Linux](https://snapcraft.io/microk8s). Perfect for:
- Developer workstations
- IoT
- Edge
- CI/CD
> Canonical might have assembled the easiest way to provision a single node Kubernetes cluster - [Kelsey Hightower](https://twitter.com/kelseyhightower/status/1120834594138406912)
## Why MicroK8s?
- **Small**. Developers want the smallest K8s for laptop and workstation
development. MicroK8s provides a standalone K8s compatible with Azure
AKS, Amazon EKS, Google GKE when you run it on Ubuntu.
- **Simple**. Minimize administration and operations with a single-package
install that has no moving parts for simplicity and certainty. All
dependencies and batteries included.
- **Secure**. Updates are available for all security issues and can be
applied immediately or scheduled to suit your maintenance cycle.
- **Current**. MicroK8s tracks upstream and releases beta, RC and final bits
the same day as upstream K8s. You can track latest K8s or stick to any
release version from 1.10 onwards.
- **Comprehensive**. MicroK8s includes a curated collection of manifests for
common K8s capabilities and services:
- Service Mesh: Istio, Linkerd
- Serverless: Knative
- Monitoring: Fluentd, Prometheus, Grafana, Metrics
- Ingress, DNS, Dashboard, Clustering
- Automatic updates to the latest Kubernetes version
- GPGPU bindings for AI/ML
Drop us a line at [MicroK8s in the Wild](docs/community.md) if you are
doing something fun with MicroK8s!
## Quickstart
Install MicroK8s with:
```
snap install microk8s --classic
```
MicroK8s includes a `microk8s kubectl` command:
```
sudo microk8s kubectl get nodes
sudo microk8s kubectl get services
```
To use MicroK8s with your existing kubectl:
```
sudo microk8s kubectl config view --raw > $HOME/.kube/config
```
#### User access without sudo
The *microk8s* user group is created during the snap installation. Users in that group
are granted access to `microk8s` commands. To add a user to that group:
```
sudo usermod -a -G microk8s <username>
```
#### Kubernetes add-ons
MicroK8s installs a barebones upstream Kubernetes. Additional services like dns and the Kubernetes dashboard can be enabled using the `microk8s enable` command.
```
sudo microk8s enable dns
sudo microk8s enable dashboard
```
Use `microk8s status` to see a list of enabled and available addons. You can find the addon manifests and/or scripts under `${SNAP}/actions/`, with `${SNAP}` pointing by default to `/snap/microk8s/current`.
## Documentation
The [official docs](https://microk8s.io/docs/) are maintained in the
Kubernetes upstream Discourse.
Take a look at the [build instructions](docs/build.md) if you want to
contribute to MicroK8s.

# Parts directory
This directory contains the build scripts for Go components built into MicroK8s.
The directory structure looks like this:
```
build-scripts/
build-component.sh <-- runs as `build-component.sh $component_name`
- checks out the git repository
- runs the `pre-patch.sh` script (if any)
- applies the patches (if any)
- runs the `build.sh` script to build the component
component/
$component_name/
repository <-- git repository to clone
version.sh <-- prints the repository tag or commit to checkout
build.sh <-- runs as `build.sh $output $version`
first argument is the output directory where
binaries should be placed, second is the component version
pre-patch.sh <-- runs as `pre-patch.sh`. takes any action needed before applying
the component patches
patches/ <-- list of patches to apply after checkout (see section below)
...
strict-patches/ <-- list of extra patches to apply when building strictly confined snap
...
```
## Applying patches
Most MicroK8s components are retrieved from an upstream source (specified in the `repository`), with a specific tag (specified in `version.sh`), have some patches applied to them (from the `patches/` and `strict-patches/` directories) and are then built (using `build.sh`).
This section explains the directory format for the `patches` and `strict-patches` directories. The same rules apply for both. Note that the `strict-patches` (if any) are applied **after** any `patches` have been applied.
Our patches do not frequently change between versions, but they do have to be rebased from time to time, which breaks compatibility with older versions. For that reason, we maintain a set of patches for each version that introduces a breaking change. Consider the following directory structure for the Kubernetes component.
```
patches/default/0.patch
patches/v1.27.0/a.patch
patches/v1.27.0/b.patch
patches/v1.27.4/c.patch
patches/v1.28.0/d.patch
patches/v1.28.0-beta.0/e.patch
```
The Kubernetes version to build may be decided dynamically while building the snap, or be pinned to a specified version. The following table shows which patches we would apply depending on the Kubernetes version that we build:
| Kubernetes version | Applied patches | Explanation |
| ------------------ | ----------------------- | ------------------------------------------------------------------------------------------ |
| `v1.27.0` | `a.patch` and `b.patch` | |
| `v1.27.1` | `a.patch` and `b.patch` | In case there is no exact match, find the most recent older version |
| `v1.27.4` | `c.patch` | Older patches are not applied |
| `v1.27.12` | `c.patch` | In semver, `v1.27.12 > v1.27.4` so we again must get the most recent patches |
| `v1.28.0-rc.0` | `d.patch` | Extra items from semver are ignored, so we can define the `v1.28.0` patch and be done |
| `v1.28.0-beta.0` | `e.patch` | Extra items from semver are ignored, but due to exact match this patch is used instead |
| `v1.28.0` | `d.patch` | Extra items from semver are ignored, so we can define the `v1.28.0` patch and be done |
| `v1.28.4` | `d.patch` | Picks the patches from the stable versions only, not from beta |
| `v1.29.1` | `d.patch` | Uses patches from most recent version, even if on a different minor |
| `hack/branch` | `0.patch` | If not semver and no match, any patches from the `default/` directory are applied (if any) |
Same logic applies for all other components as well.
### Testing which patches would be applied
You can verify which set of patches would be applied in any case using the `print-patches-for.py` script directly:
```bash
$ ./build-scripts/print-patches-for.py kubernetes v1.27.4
/home/ubuntu/microk8s/build-scripts/components/kubernetes/patches/v1.27.4/0000-Kubelite-integration.patch
$ ./build-scripts/print-patches-for.py kubernetes v1.27.3
/home/ubuntu/microk8s/build-scripts/components/kubernetes/patches/v1.27.0/0000-Kubelite-integration.patch
/home/ubuntu/microk8s/build-scripts/components/kubernetes/patches/v1.27.0/0001-Unix-socket-skip-validation-in-component-status.patch
$ ./build-scripts/print-patches-for.py kubernetes v1.28.1
/home/ubuntu/microk8s/build-scripts/components/kubernetes/patches/v1.28.0/0001-Set-log-reapply-handling-to-ignore-unchanged.patch
/home/ubuntu/microk8s/build-scripts/components/kubernetes/patches/v1.28.0/0000-Kubelite-integration.patch
```
### How to add support for newer versions
When a new release comes out which is no longer compatible with the existing latest patches, simply create a new directory under `patches/` with the new version number. This ensures that previous versions will still work, and newer ones will pick up the fixed patches.
