ci(release): guard prerelease tags from clobbering :latest / Homebrew#76
Merged
Conversation
…table
A v*-rc* tag triggered the same release pipeline as a stable tag, which
would publish a normal release, overwrite ghcr.io/0xmassi/webclaw:latest,
and repoint the Homebrew formula at the rc — shipping a prerelease to every
stable Docker/brew user. Guard all three on the SemVer prerelease hyphen:
- release: add --prerelease for hyphenated tags
- docker: still push :${tag} (testable rc image) but only move :latest for stable
- homebrew: skip entirely for prereleases
Lets us cut rc tags (e.g. to validate the new musl build job) without
touching stable users.

Prep for cutting validation rc tags (e.g. to exercise the new musl build job from #75) without shipping an rc to stable users.
Problem
Any
v*tag runs the full release pipeline. For a prerelease likev0.6.14-rc1that meant:ghcr.io/0xmassi/webclaw:latestoverwritten with the rc image,brew install webclawgets it).Fix
Guard all three on the SemVer prerelease hyphen (
v1.2.3-rc1contains-):--prereleasefor hyphenated tags.:${tag}(so the rc image is testable) but only move:latestfor stable tags.Stable tags (
v0.6.14) are unaffected — verified the shell hyphen-detection both ways. Pure CI change; the build/test jobs are untouched.
