REPO_POLICIES.md requires the container build to run the checks; the
Dockerfile only compiled the binary, so script/cibuild checked nothing. A
new lint stage on the golangci-lint v2.7.2 image runs make fmt-check and
make lint, and the build stage waits for it and then runs make test, so
make docker now fails when formatting, lint or a test fails. All three base
images are pinned by digest with their versions unchanged. The final image
and how it starts are unchanged.
make docker is now the gate to use on hosts where the installed linter is
older than the Go toolchain and make lint cannot run directly.
Model: opus-4-8 (implementation, review); fable-5-1 (summary)
Use runuser to drop privileges and execute the app as the routewatch
user (uid 1000). Fix data directory permissions at runtime since host
mounts may have incorrect ownership.
- Builder stage: vendor dependencies, build binary, create source archive
- Source archive (.tar.zst) includes all code and vendored dependencies
- Runtime stage: minimal Debian image with binary and source archive
- Health check via curl to /.well-known/healthcheck.json
- Runs as non-root user (routewatch:1000)
