Description

Docker can check containers for if their services are alive. This can/should be built into the container image itself and is basically a command that checks if the service is alive and kicking.

It would be easy enough if the API had some form of public /health endpoint (I looked, but couldn't find one. The /version endpoint requires a login).

If that occurred, we'd be able to do a healthcheck with something like:

    healthcheck:
      test: curl -fSs 127.0.0.1:3000/api/v1/health || exit 1
      start_period: 60s
      interval: 5s
      timeout: 10s
      retries: 3
