## Notes
160+
161+
- The `SIGQUIT` signal will be sent to nginx to stop this container, to give it an opportunity to stop gracefully (i.e, finish processing active connections). The Docker default is `SIGTERM`, which immediately terminates active connections. Note that if your configuration listens on UNIX domain sockets, this means that you'll need to manually remove the socket file upon shutdown, due to [nginx bug #753](https://trac.nginx.org/nginx/ticket/753).
