# Builds the image on every push to main and pushes it to Gitea's container
|
|
# registry as "latest" (after first re-tagging the current "latest" as
|
|
# "previous", for a one-step-back rollback point -- no-ops on the very first
|
|
# run, when there's no existing "latest" to promote). Deliberately just
|
|
# "latest"/"previous", not per-commit tags, to avoid accumulating history.
|
|
# See release.yml for tagged releases (git tag -> matching image tag).
|
|
#
|
|
# This project's CI/CD scope is intentionally just test/build/push --
|
|
# deployment is being split into a separate project.

#

|
# Requires secrets.BUILD_API_TOKEN -- a personal access token
|
|
# (write:package scope) from the pushing account, stored manually as a repo
|
|
# secret. The auto-injected secrets.GITEA_TOKEN does NOT work for this: it
|
|
# never grants package-registry access regardless of the workflow's own
|
|
# `permissions:` block -- a known Gitea limitation, not a config mistake
|
|
# (https://github.com/go-gitea/gitea/issues/23642).
