name: Deploy backend to beta VPS
|
|
|
|
# On a push to `main` that touches backend/**, SSH to beta and roll ONLY the
|
|
# backend service onto the image backend-build-push.yml just published for
|
|
# this commit. Frontend is deployed independently by frontend-deploy.yml --
|
|
# the FE/BE CI-CD split survives reunification intact: a backend change ships
|
|
# without touching frontend and vice versa. infra/deploy/deploy.sh persists
|
|
# each service's live tag host-side, so a single-service roll never disturbs
|
|
# the other. An infra-only push rolls nothing (infra-sync.yml syncs the
|
|
# host checkouts instead); a mixed backend+frontend push fires both deploy
|
|
# workflows, serialized host-side by deploy.sh's flock.
|
|
#
|
|
# The SSH_HOST/USER/KEY/PORT secrets point at beta. appleboy/ssh-action is
|
|
# referenced by full GitHub URL because it isn't mirrored in Forgejo's default
|
|
# action registry.
|
|
#
|
|
# The tag MUST match backend-build-push.yml's `sha-${GITHUB_SHA:0:12}` (12
|
|
# hex), not the full 40-char ${{ github.sha }} -- default Actions expressions
|
|
# have no substring function, so the compute step below truncates it.
|
|
# deploy.sh also retries the pull for ~5 min because Forgejo `needs:` can't
|
|
# gate across the separate build-push workflow, so this push's build may still
|
|
# be in flight.
