Local Container Preflight (tools/local/local_container_build.sh)

Use this helper to validate the Docker images locally before cutting a release.

Usage

• Build images only:

./tools/local/local_container_build.sh

• Build + smoke test (start compose, wait for pypnm-api health, then tear down):

./tools/local/local_container_build.sh --smoke

Requirements

• Docker Engine with buildx and the docker compose plugin (on Debian/Ubuntu you can install docker.io docker-buildx-plugin docker-compose-plugin, or use the official Docker CE repo). See Install Docker prerequisites if Docker is not set up yet.
• Daemon access (run with sudo or add your user to the docker group if needed).
• If buildx is missing, Docker falls back to the legacy builder and emits a deprecation warning during image builds.

What it does

1. Builds compose images (docker compose --progress plain build).
2. If --smoke is set, brings up the stack, waits for pypnm-api to become healthy, then tears down (docker compose down --volumes).
