Dockerfile multiple start commands with ctrl-c and graceful stop

StopDocker.md

Initially I had the nginx command in the start script, but BASH was ignoring SIGINT signals, or capturing them but not forwarding them to the Nginx daemon.

This snippet allows docker stop <hash> to shutdown the container properly, without waiting the default 10 seconds for cleanup, and ctrl-c works as expected.

Dockerfile

CMD /app/start.sh && \
  exec nginx -g 'daemon off;'

CLI

$ docker run -it <hash>
