Docker container wont stay up

[SephVelut]

So from my understanding as long as the process in the container is started, then docker will keep it running.

I have a base ubuntu image with apache installed. I run docker run -d <image> service apache2 start. The container does not stay up though..

4e56cadad902 | 3d0e65e37f75 | "service apache2 sta | 4 seconds ago | Exited (0) 3 seconds

docker logs <id> returns * Starting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.19 for ServerName ...done..

I verified that apache starts just fine in the image. But docker ps does not show the container. What am I doing wrong?

@SephVelut Try docker run docker run -dit <image> service apache2 start

The -i and -t flag allocate an interactive tty.

Same result. Exited (0)

Hi,

service apache2 start will daemonize the apache process. This means that it exits as the foreground task (the one you’re using) and then goes into the background where it runs independently.

Docker does not accommodate this use case, preferring applications run in the foreground. What you will need to do is determine how apache needs to start and plug that command in directly. It will depend on your apache configuration.

This is covered by the documentation at http://docs.docker.com, and is not a docker bug, so I'm going to close this.
