| # Reusable workflow for building and pushing a bake target. | ||
| # Replaces build-docker-image.yml for apps migrated to docker-bake.hcl. | ||
| # | ||
| # Callers pass app-specific build args via the `set` input using GitHub Variables | ||
| # (vars.*) for NEXT_PUBLIC_* values — these are public by design and belong in | ||
| # vars, not secrets. Sentry secrets are declared explicitly below. | ||

| Pre-built base image tag (BASE_TAG). When set, pulls ui-builder-base | ||
| and ui-runner-base from the registry instead of building them inline. | ||
| Use this in CI to avoid rebuilding base images on every app push. | ||
| Omit (or leave empty) to build base images inline — useful when | ||
| testing base image changes locally via act or in build-base-images.yml. | ||
| platforms: | ||
| required: false | ||

| type: string | ||
| default: "" | ||
| description: > | ||
| Extra bake --set overrides (newline-separated target.field=value pairs). | ||
| Use this to inject app-specific build args, e.g.: | ||
| techlabblog.args.NEXT_PUBLIC_APP_URL=${{ vars.TECHLABBLOG_APP_URL }} | ||
| Note: GitHub Variables (vars.*) are available here; secrets are not — | ||
