This is good practice because the logs will be available all along and cleanup is built into the workflow. Starting your containers with docker-compose up and stopping them with docker-compose down when you finished your activities, will remove all containers and networks involved with the application automatically.The downside of this method is that you’ll not be able to access the Docker logs after the container exits. Starting your Docker containers with docker container run -rm tells Docker to remove the container when it exits.In all these cases the containers will remain on your system and you’ll want to clean them up after a while.īefore we move to the cleaning instructions, let me give you a few tips to remove containers as part of your workflow:
