If you\njust want to use NATS server, then head over to [Docker Hub]. You don't need\nthis repository.\n\nThe rest of this readme is for image maintainers.\n\n## Directory structure\n\nThe directories are structured in a way such that each NATS server release has\na directory. Each release version has a number of base image variants, such as\nscratch on Linux or nanoserver on Windows.\n\n```\nnats-docker/\n├── 2.9.x\n│   ├── image variant 1\n└───└── image variant 2\n├── 2.10.x\n│   ├── image variant 1\n└───└── image variant 2\n```\n\nFor the most part, image variant Dockerfiles will download the official NATS\nserver [release binaries] when building the server image and `COPY` a default\nconfiguration file.\n\nThe Linux scratch image is a little special. It copies a server binary from the\nAlpine image because the scratch image doesn't come with any tools to download\nand untar binaries.\n\n## Updating NATS server version\n\nFirst, make sure you've published a new NATS server git tag and make sure the\n[release binaries] and SHASUMS are ready to download.\n\nNext, run the command below. This will update the version and hash of the NATS\nserver. If this is a patch release, it will update the existing directory.\nHowever, if it is a minor or major version, it will create the new directory\n(if required) from the latest minor version.\n\n```\nusage: ./update.py \n ./update.py 2.10.0\n```\n\nYou can check what changed with `git diff`.\n\n## Manual updates\n\nThis script doesn't update everything. Here are some other things you\nmay or may not want to update.\n\n- The Ubuntu host version used for CI.\n- The Windows host versions used for CI.\n- The Alpine version\n\nAfter you've updated everything that needs updating. Submit a PR to this repo.\nMake sure CI passes.\n\n## Publishing on Docker Hub\n\nTo publish your new changes to Docker Hub. Head over to\n[docker-library/official-images]. You'll need to update the [nats IMF] file.\n\nIMF stands for Internet Message Format. It's the format that Docker chose to\ndeclare images, instead of something like YAML.\n\nYou'll need to update the git commit in this file.\n\n```\nGitCommit: 710f0ed18645d78e97fa7fd8cdf9b80dbe936eb6\n```\n\nAlso handy to know, if you're testing and haven't merged your PR in\nnats-io/nats-docker. You can tell Docker to pull a commit from a different\nbranch like this.\n\n```\nGitFetch: refs/heads/mybranch\nGitCommit: 710f0ed18645d78e97fa7fd8cdf9b80dbe936eb6\n```\n\nDocker images will be built in the order they're specified in the IMF file.\nThis detail is very important because Windows images and the scratch image\ndepend on this behavior. Nanoserver images must be built after servercore\nimages. Scratch must be built after Alpine.\n\n```\nTags: 2.1.0-windowsservercore-1809, windowsservercore-1809\nArchitectures: windows-amd64\nDirectory: 2.1.0/windowsservercore-1809\nConstraints: windowsservercore-1809\n\nTags: 2.1.0-nanoserver-1809, nanoserver-1809\nArchitectures: windows-amd64\nDirectory: 2.1.0/nanoserver-1809\nConstraints: nanoserver-1809, windowsservercore-1809\n```\n\nThe names of the images also have to be consistent with the rest of the\nofficial images. Make sure the names match existing image names. For example,\nit should be `2.1.0-windowsservercore-1809`, not `2.1.0-windowsservercore1809`,\nnot `2.1.0-servercore-1809`.\n\n[Docker Hub]: https://hub.docker.com/_/nats\n[docker-library/official-images]: https://github.com/docker-library/official-images\n[License-Image]: https://img.shields.io/badge/License-Apache2-blue.svg\n[License-Url]: https://www.apache.org/licenses/LICENSE-2.0\n[nats IMF]: https://github.com/docker-library/official-images/blob/master/library/nats\n[NATS server Docker images]: https://hub.docker.com/_/nats\n[release binaries]: https://github.com/nats-io/nats-server/releases\n" }, { "path": "update.py", "content": "#!/usr/bin/env python3\n\nimport os\nimport re\nimport sys\nimport glob\nimport shutil\nimport typing\nimport urllib.request\n\nsemver_str = r\"([0-9]+)\\.([0-9]+)\\.([0-9]+)(-(preview|rc|RC)\\.([0-9]+))?\"\nsha256_str = r\"[A-Fa-f0-9]{64}\"\ndefault_sha256 = \"0000000000000000000000000000000000000000000000000000000000000000\"\n\n\n# Update the NATS_SERVER env variable across applicable files.\ndef update_env_var(base_dir: str, new_ver: str):\n files = [\n f\"./{base_dir}/windowsservercore-ltsc2022/Dockerfile\",\n f\"./{base_dir}/windowsservercore-ltsc2025/Dockerfile\",\n f\"./{base_dir}/tests/build-images.sh\",\n f\"./{base_dir}/tests/run-images.sh\",\n f\"./{base_dir}/tests/build-images-ltsc2022.ps1\",\n f\"./{base_dir}/tests/build-images-ltsc2025.ps1\",\n f\"./{base_dir}/tests/run-images-ltsc2022.ps1\",\n f\"./{base_dir}/tests/run-images-ltsc2025.ps1\",\n ] + glob.glob(f\"./{base_dir}/alpine*/Dockerfile\")\n\n r = re.compile(r\"(NATS_SERVER )\" + semver_str)\n\n for f in files:\n with open(f, \"r\") as fd:\n data = fd.read()\n\n with open(f, \"w\") as fd:\n fd.write(r.sub(f\"\\g<1>{new_ver}\", data))\n\n\n# Update the nats:x.y.z tag across applicable files.\ndef update_tag_var(base_dir: str, new_ver: str):\n files = [\n f\"./{base_dir}/nanoserver-ltsc2022/Dockerfile\",\n f\"./{base_dir}/nanoserver-ltsc2025/Dockerfile\",\n f\"./{base_dir}/scratch/Dockerfile\",\n ]\n\n r = re.compile(r\"(--from=nats:)\" + semver_str)\n\n for f in files:\n with open(f, \"r\") as fd:\n data = fd.read()\n\n with open(f, \"w\") as fd:\n fd.write(r.sub(f\"\\g<1>{new_ver}\", data))\n\n\n# Update the nats:x.y.z tag across applicable files.\ndef update_preview_tag_var(base_dir: str, new_ver: str):\n files = [\n f\"./{base_dir}/nanoserver-ltsc2022/Dockerfile.preview\",\n f\"./{base_dir}/nanoserver-ltsc2025/Dockerfile.preview\",\n f\"./{base_dir}/scratch/Dockerfile.preview\",\n ]\n\n r = re.compile(r\"(BASE_IMAGE=nats:)\" + semver_str)\n\n for f in files:\n with open(f, \"r\") as fd:\n data = fd.read()\n\n with open(f, \"w\") as fd:\n fd.write(r.sub(f\"\\g<1>{new_ver}\", data))\n\n\n# Update the NATS SHASUM across applicable files.\ndef update_windows_shasums(base_dir: str, new_ver: str, shasums: typing.Dict):\n files = [\n f\"{base_dir}/windowsservercore-ltsc2022/Dockerfile\",\n f\"{base_dir}/windowsservercore-ltsc2025/Dockerfile\",\n ]\n\n key = f\"nats-server-v{new_ver}-windows-amd64.zip\"\n sha = shasums.get(key, default_sha256)\n\n r = re.compile(r\"(NATS_SERVER_SHASUM )\" + sha256_str)\n\n for f in files:\n with open(f, \"r\") as fd:\n data = fd.read()\n\n with open(f, \"w\") as fd:\n fd.write(r.sub(f\"\\g<1>{sha}\", data))\n\n\ndef update_alpine_shasums(base_dir: str, new_ver: str, shasums: typing.Dict):\n file = glob.glob(f\"{base_dir}/alpine*/Dockerfile\")[0]\n\n with open(file, \"r\") as fd:\n data = fd.read()\n\n arches = (\"arm64\", \"arm6\", \"arm7\", \"amd64\", \"386\", \"s390x\", \"ppc64le\")\n if base_dir != \"2.10.x\":\n arches += (\"loong64\",)\n\n for arch in arches:\n key = f\"nats-server-v{new_ver}-linux-{arch}.tar.gz\"\n arch_sha = shasums.get(key, default_sha256)\n r = re.compile(f\"(natsArch='{arch}';
