name: Deploy backend to prod VPS
|
|
|
|
# On a push to `release` that touches backend/**, SSH to prod and roll ONLY
|
|
# the backend service onto the image backend-build-push.yml published for this
|
|
# commit. Same shape as backend-deploy.yml (the `main`->beta path) against a
|
|
# completely separate secret set (PROD_SSH_HOST/USER/KEY/PORT) so a beta
|
|
# credential leak can't reach prod. Frontend deploys itself independently via
|
|
# frontend-deploy-prod.yml -- a backend change ships to prod without touching
|
|
# frontend and vice versa, exactly as in the split era.
|
|
#
|
|
# The tag MUST match backend-build-push.yml's last-backend-commit key (12
|
|
# hex) -- see backend-deploy.yml for why it's truncated here. deploy.sh
|
|
# retries the pull because the build for this push may still be in flight.
