Permissions

Scope	Access	Description

packages	write	Push charts to OCI registry (ghcr.io)

Notes

• Uses helm/chart-releaser-action to automatically detect chart version changes and create corresponding GitHub releases.
• Only creates releases for charts that have version bumps compared to the previous release.
• Charts are published to the OCI registry (ghcr.io/<owner>/<repo>) in addition to GitHub releases.
• If HELM_REPOS is provided, adds external repositories before packaging (useful for charts with dependencies).
• Requires chart versions to follow semantic versioning.
• Automatically configures Git user as github-actions[bot] for any commits made during the release process.
• Charts can be pulled using: helm pull oci://ghcr.io/<owner>/<repo>/<chart-name> --version <version>
