entrypoint.sh

#!/bin/bash -e

# Container entrypoint to simplify running the production and dev servers.

# Entrypoint conventions are as follows:
#
#  -  If the container is run without a custom CMD, the service should run as it would in production.
#  -  If the container is run with the "dev" CMD, the service should run in development mode.
#
#     Normally, this means that if the user's source has been mounted as a volume, the server will
#     restart on code changes and will inject extra debugging/diagnostics.
#
#  -  If the CMD is "test" or "lint", the service should run its unit tests or linting.
#
#     There is no requirement that unit tests work unless user source has been mounted as a volume;
#     test code should not normally be shipped with production images.
#
#  -  Otherwise, the CMD should be run verbatim.
