CloudContainerNamespace/CloudContainerStub aliases (a container binding is a DO namespace), header-table row, README binding tables + Containers section with per-target support matrix.
- schema: 'docker' driver reserved + per-target registry block (Harbor) - config.mjs: parse wrangler 'containers' array; expose containers + containerBindings (DO binding name -> container entry) - host.mjs: container-backed DO bindings boot cleanly and throw UnsupportedBindingError on first use (with hint), instead of crashing - createUnsupportedBinding gains optional hint param - sample configs: commented reserved registry/driver shapes
- images.mjs: detectBuilder (buildah>docker), build, skopeo copy push (sha + latest tags), inspect, status; digest pins in .mieweb/images.lock.json - registry login/logout via skopeo (authFile, password prompted, never argv) - index.mjs: 'images'/'registry' verbs; cloudflare push delegates to 'wrangler containers push' - packages/cli README with Images section (prereqs, conventions, lockfile)
buildah build + skopeo copy to Harbor with a robot account, digest lockfile bump committed by CI. Example only — runs in consuming apps once the opensource-server cluster (Forgejo+Harbor) is up.
