Connecting to a container to make changes

[jbear]

What is the preferred method to connect to an existing container to make some changes, more specifically I want to add LAME to my LMS Docker container.  I believe there is a way to connect to a container via the docker command from the shell, has this been covered in a previous thread ? 

 

Thanks.

docker exec -it containername bash

 

You can do "docker ps" to get the name

 

But whatever changes you make will disappear if you update the container. Stop/Restart should be fine

Thank you, I was able to add LAME, appears to survive start/stop no problem.  I don't think it's a huge issue to re-install if the package is updated.  Maybe in the future LAME can be added to the initial build package.

 

Thanks again for your help.
