Rhdh Decommission Release

Decommission RHDH Release Branch Jobs

You are helping the user decommission CI jobs for an end-of-life RHDH (Red Hat Developer Hub) release branch.

What This Command Does

Decommissioning removes all CI configuration for a given RHDH release branch. This is done when a release reaches end-of-life and no longer needs CI jobs running. Based on the pattern from PR #71895.

Steps to follow:

• Get the release version:
• If the user provided a version (e.g., "1.7", "1.8"), use it directly
• If no version was provided, ask the user for the RHDH release version to decommission
• List existing release configs to help the user choose:
• ls ci-operator/config/redhat-developer/rhdh/redhat-developer-rhdh-release-*.yaml

• Verify the files to be removed:

Show the user what will be deleted and ask for confirmation:

• CI config file: ci-operator/config/redhat-developer/rhdh/redhat-developer-rhdh-release-{version}.yaml
• Generated job files: ci-operator/jobs/redhat-developer/rhdh/redhat-developer-rhdh-release-{version}-*.yaml (typically -presubmits.yaml and -periodics.yaml)
• Branch protection entry: The release-{version}: block in core-services/prow/02_config/redhat-developer/rhdh/_prowconfig.yaml

If the CI config file does not exist, warn the user that this release may have already been decommissioned and ask if they want to continue checking for leftover files.

• Delete the CI config file:

Remove ci-operator/config/redhat-developer/rhdh/redhat-developer-rhdh-release-{version}.yaml

• Delete the generated job files:

Remove all matching files: ci-operator/jobs/redhat-developer/rhdh/redhat-developer-rhdh-release-{version}-*.yaml

• Remove branch protection configuration:

Edit core-services/prow/02_config/redhat-developer/rhdh/_prowconfig.yaml to remove the entire release-{version}: block under branch-protection.orgs.redhat-developer.repos.rhdh.branches.

The block to remove looks like:

               release-{version}:
                 allow_deletions: false
                 allow_force_pushes: false
                 enforce_admins: true
                 protect: true
                 required_status_checks:
                   contexts:
                   - <context1>
                   - <context2>
                   - <context3>

Be careful to:

• Only remove the block for the specified version
• Preserve indentation and formatting of surrounding blocks
• Not leave blank lines where the block was removed

• Confirm completion: Summarize what was removed:
• List deleted files
• Confirm branch protection entry was removed
• Remind the user to commit the changes and create a PR

Important Notes

• Do NOT run make update -- since we are only deleting files and removing branch protection, there is nothing to regenerate
• The generated job files in ci-operator/jobs/ are normally auto-generated, but when decommissioning we simply delete them along with the source config
• Always verify the files exist before attempting deletion
• This operation is destructive -- always confirm with the user before proceeding
