Running migrations

Never run migrations from the container entrypoint. docker/prod/entrypoint.sh deliberately does not — with several replicas, per-container migrations race against the same database. docker/prod/release.sh is the one-shot release step, run once per deploy:

docker run --rm --env-file <your prod env file> <image> docker/prod/release.sh

The two topologies below each have their own way of invoking it.
