release.yml

name: Release

# Triggered by SemVer tags. Stable tags (v1.2.3) cut a final release; tags
# carrying a -alpha.N / -beta.N / -rc.N suffix cut a GitHub *prerelease* and
# do NOT move the `latest` / `1` / `1.2` Docker tags.
#
# Examples:
#   v1.2.3            -> ghcr.io/.../devlane-{api,ui}:1.2.3, :1.2, :1, :latest
#   v1.2.3-beta.4     -> ghcr.io/.../devlane-{api,ui}:1.2.3-beta.4 (only)
#   v1.2.3-alpha.345  -> ghcr.io/.../devlane-{api,ui}:1.2.3-alpha.345 (only)
