Release process guidance

Pre-reqs

1. Make sure you have enterprise remote configured

git remote add enterprise <url>

2. Make sure you have singing key configured
3. Make sure you have github token with at least read:org, repo, write:packages permissions exported under GITHUB_TOKEN env variable. You can create token here
4. Make sure you're authorized for pushing docker images

For MacOS users

Make sure you have GNU version of utilities zip, tar, sha256sum. To install them run the following commands:

brew install coreutils
brew install gnu-tar
export PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"

Docker may need additional configuration changes:

docker buildx create --use --name=qemu
docker buildx inspect --bootstrap  

For ARM arch (M1/M2 processors) additionally configure docker with preferred platform:

export DOCKER_DEFAULT_PLATFORM=linux/amd64

By default, docker on MacOS has limited amount of resources (CPU, mem) to use. Bumping the limits may significantly improve build speed.

Release version and Docker images

0. Make sure that the release commits have no security issues. 1a. Document all the changes for new release in CHANGELOG.md and update version if needed in SECURITY.md 1b. Add (available starting from v1.xx.y) line to feature docs introduced in the upcoming release. 1c. Cut new version in CHANGELOG.md and make it merged. See example in this commit. 1d. Cherry-pick all changes from master to cluster branch, and to ENT branches enterprise-single-node, enterprise-cluster. 1e. Cherry-pick bug fixes relevant for LTS releases.
1. Make sure you get all changes fetched git fetch --all.
2. Create the following release tags:
   • git tag -s v1.xx.y in master branch
   • git tag -s v1.xx.y-cluster in cluster branch
   • git tag -s v1.xx.y-enterprise in enterprise branch
   • git tag -s v1.xx.y-enterprise-cluster in enterprise-cluster branch
3. Run TAG=v1.xx.y make publish-release. This command performs the following tasks: a) Build and package binaries in *.tar.gz release archives with the corresponding _checksums.txt files inside bin directory. This step can be run manually with the command make release from the needed git tag. b) Build and publish multi-platform Docker images for the given TAG, TAG-cluster, TAG-enterprise and TAG-enterprise-cluster. The multi-platform Docker image is built for the following platforms:
   • linux/amd64
   • linux/arm64
   • linux/arm
   • linux/ppc64le
   • linux/386 This step can be run manually with the command make publish from the needed git tag.
4. Push the tags v1.xx.y and v1.xx.y-cluster created at step 2 to public GitHub repository at https://github.com/VictoriaMetrics/VictoriaMetrics. Push the tags v1.xx.y, v1.xx.y-cluster, v1.xx.y-enterprise and v1.xx.y-enterprise-cluster to the corresponding branches in private repository. Important note: do not push enterprise tags to public GitHub repository - they must be pushed only to private repository.
5. Run TAG=v1.xx.y make github-create-release github-upload-assets. This command performs the following tasks: a) Create draft GitHub release with the name TAG. This step can be run manually with the command TAG=v1.xx.y make github-create-release. The release id is stored at /tmp/vm-github-release file. b) Upload all the binaries and checksums created at step 3a to that release. This step can be run manually with the command make github-upload-assets. It is expected that the needed release id is stored at /tmp/vm-github-release file, which must be created at the step a. If the upload process is interrupted by any reason, then the following recovery steps must be performed:
   • To delete the created draft release by running the command make github-delete-release. This command expects that the id of the release to delete is located at /tmp/vm-github-release file created at the step a.
   • To run the command TAG=v1.xx.y make github-create-release github-upload-assets, so new release is created and all the needed assets are re-uploaded to it.
6. Go to https://github.com/VictoriaMetrics/VictoriaMetrics/releases and verify that draft release with the name TAG has been created and this release contains all the needed binaries and checksums.
7. Update the release description with the content of CHANGELOG for this release.
8. Publish release by pressing "Publish release" green button in GitHub's UI.
9. Bump version of the VictoriaMetrics cluster in the sandbox environment by opening and merging PR.
10. Bump VictoriaMetrics version at deployment/docker/docker-compose.yml and at deployment/docker/docker-compose-cluster.yml.

Building snap package

pre-requirements:

• snapcraft binary, can be installed with commands: for MacOS brew install snapcraft and install multipass, for Ubuntu - sudo snap install snapcraft --classic
• exported snapcraft login to ~/.snap/login.json with snapcraft export-login login.json && mkdir -p ~/.snap && mv login.json ~/.snap/
• already created release at github (it operates git describe version, so git tag must be annotated).

1. checkout to the latest git tag for single-node version.
2. execute make release-snap - it must build and upload snap package.
3. promote release to current, if needed manually at release page snapcraft-releases
