The image HEALTHCHECK became /app/healthcheck.sh when the worker role was
added (54ad7ee8), but the container smoke still required the old inline curl
probe, so every Server image validation since then failed before publishing.
Expect the script form and describe it in the storage docs.
- Run as the .NET image's non-root app user (UID 1654) with root-owned
application files and an app-owned /app/data that fresh named volumes inherit.
- Add a curl HEALTHCHECK on /healthz (30s/5s/10s/3, 2s start interval), keep the
explicit 8090 URL and clear the base image's 8080 port default.
- Parameterize VERSION/SOURCE_REVISION and base images; add OCI labels with
development defaults.
- Add an image-only Compose example (required image and bind address, named
volume, cap_drop ALL, no-new-privileges) and an env template.
- Document deployment, the upload limit, scoped ownership preparation, and
checked backup/restore/upgrade functions that refuse existing destinations and
verify the metadata list and every archive hash before switching volumes.
- Extend the container smoke: image user/healthcheck/label contract, PID 1 UID,
capabilities and writable paths, Docker-reported health, near-limit and
oversized uploads, stopped-service backup restored into a second volume, and
startup failure on read-only and root-owned data mounts.
