# workflow-prepare.sh — stamp the release version into version.go at build time.
|
|
#
|
|
# The shared go-release workflow (lukaszraczylo/shared-actions go-release.yaml)
|
|
# runs this script, if present, from the repository root BEFORE GoReleaser
|
|
# builds and tags. Traefik runs this plugin under Yaegi, where the version
|
|
# cannot be resolved from build info at runtime, so the released semver must be
|
|
# baked into source here.
|
|
#
|
|
# Version source — first non-empty wins:
|
|
# $VERSION $VERSION_TAG $SEMVER $NEW_VERSION $RELEASE_VERSION
|
|
# A leading "v"/"V" is stripped.
|
|
#
|
|
# go-release.yaml's release job already exposes the computed version to this
|
|
# script's environment (shared-actions commit 58ab34e, "Run workflow prepare
|
|
# script" step): VERSION carries the bare semver, VERSION_TAG the v-prefixed
|
|
# form. Stamping works end-to-end with no extra wiring in this repo.
|
|
#
|
|
# The shared workflow runs this script in its test, version AND release jobs,
|
|
# but only the release job's step sets that env — the test/version jobs run
|
|
# it with no version at all. So a missing version is a no-op (leave the dev
|
|
# sentinel) — NOT a hard failure, otherwise the test/version jobs would
|
|
# break. A malformed version that IS provided is a hard error.
