Releasing the operator

Preparing a new release branch

For a major or minor release, you will need to create a new release-vX.Y branch based on the target minor version.

Create the next minor release's first milestone at https://github.com/tigera/operator/milestones. This would mean if the branch release-v1.30 is being created, then the milestone v1.31.0 should be created too. This ensures that new PRs against master will be automatically given the correct tag.

Preparing for the release

Review the milestone for this release and ensure it is accurate. https://github.com/tigera/operator/milestones

Updating versions

Checkout the branch from which you want to release. Ensure that you are using the correct operator version for the version of Calico or Calient that you are releasing. If in doubt, check the releases page to find the most recent Operator release for your Calico or Calient minor version.

Make sure pins are updated in go.mod

Run the following command:

make release-prep GIT_PR_BRANCH_BASE=<RELEASE_BRANCH> GIT_REPO_SLUG=tigera/operator CONFIRM=true \
  VERSION=<OPERATOR_VERSION> CALICO_VERSION=<CALICO_VERSION> CALICO_ENTERPRISE_VERSION=<CALICO_ENTERPRISE_VERSION> COMMON_VERSION=<COMMON_VERSION>

The command does the following:

  • It updates the image version and the title field with the appropriate versions in the format vX.Y.Z for each of the following files:

    1. config/calico_versions.yml (Calico OSS version)
    2. config/enterprise_versions.yml (Calico Enterprise version)

  • It updates the registry reference to quay.io from gcr.io for each of the following files:

    1. TigeraRegistry in pkg/components/images.go
    2. defaultEnterpriseRegistry in hack/gen-versions/main.go

  • It ensures make gen-versions is run and the resulting updates committed.

  • It creates a PR with all the changes

Go to the PR created and:

  1. Ensure tests pass
  2. Update the labels in the PR to include docs-not-required and release-note-not-required

Releasing

  1. Merge your PR to the release branch

  2. Create a git tag for the new commit on the release branch and push it:

git tag v1.30.3
git push --tags
  1. Log in to semaphore and find the new build for the release branch commit, and click 'Rerun'. When Semaphore starts the rebuild, it will notice the new tag and build and publish an operator release.

Release notes and milestones

  1. Run the following command to generate release notes for the release

    GITHUB_TOKEN=<access-token> VERSION=<TAG> ./generate-release-notes.py

  2. Go to https://github.com/tigera/operator/releases and edit the release tag to include the generated release notes, and update the title.

  3. Close the milestone for this release. https://github.com/tigera/operator/milestones

  4. Go to https://github.com/tigera/operator/milestones and create any new milestones that should exist

    • Create the next patch version
    • If a new minor was released (.0), also ensure the next minor has been created (this should have already been created as part of Preparing a new release branch)

Updates for new Calico CRDs

(TODO: We need to be able to detect new CRDs and do this automatically)

If the release includes new Calico CRDs, add the new CRDs to hack/gen-bundle/get-manifests.sh and config/manifests/bases/operator.clusterserviceversion.yaml.

Publishing a release on the RH Catalog

(Note: We are not currently publishing to RH Catalog, but we will resume soon. These notes are left here for current and future reference.)

We currently only publish operator releases targeting Calico. If the release targets Calico, continue onto the following steps to generate the operator bundle for it, and publish the release on the RH Catalog.

Before beginning, ensure that the docs at docs.projectcalico.org for the Calico version this operator release targets is live.

  1. After the semaphore job in the releasing steps is complete, and images have been tagged and pushed, checkout the tag you released and create a new branch.

  2. Login to our operator project on connect.redhat.com and publish the operator image on the RH Catalog. This step needs to happen before we generate and submit the operator bundle.

  3. Create the operator bundle using make bundle with the required variables VERSION, PREV_VERSION, CHANNELS, and DEFAULT_CHANNEL:

    Note: the version strings in VERSION and PREV_VERSION are semver strings without the v.

    • VERSION: this release version. E.g. 1.13.1
    • PREV_VERSION: the latest published bundle version in this release stream. Navigate to the certified operators production catalog and look for the most recent version from this release branch. E.g., if this release is v1.24.11 but the most recently published v1.24.x bundle is 1.24.9 then you would use VERSION=1.24.11 and PREV_VERSION=1.24.9. If this release is the first in this release branch, then there is no prior version so set PREV_VERSION=0.0.0.
    • CHANNELS and DEFAULT_CHANNEL: should be set to the release branch of this operator release. E.g., if the operator release tag is v1.23.5, then CHANNELS and DEFAULT_CHANNEL should be release-v1.23.

    For example:

    make bundle VERSION=1.13.1 PREV_VERSION=1.13.0 CHANNELS=release-v1.13 DEFAULT_CHANNEL=release-v1.13

    This step will create the bundle bundle/1.13.1.

  4. Publish the generated operator bundle following the Operator Certification CI Pipeline instructions. Bundles are no longer committed in this repository as they are committed in redhat-openshift-ecosystem/certified-operators.
