In this example I assume that you are using a tomcat contanier and a webapp deloyed in the container. Problem:  I have a webapp running in a docker container and I want to change the log level. Solution: Get a bash shell into your container. docker exec -it containerid /bin/bash Do the change that you need to do. Stop your container docker stop containerid Start your container docker start containerid This change will not get saved into the image as soon as you destory your container instance you will loose the change.

Problem: I have a running docker container how can I peek inside? Solution: docker exec -it containerid /bin/bash This will give you a bash shell in the container.
