Quitting Docker How To Stop DockerThis article explains how to stop docker container applications using docker stop, docker-compose stop and docker kill.If you have docker services or images running on your system you can verify by executing docker ps To see all of the containers even if they are not running execute add a -a If you need to to attach to a shell within the running container, run docker attach container id If docker attach never connects, run docker exec -i -t container id binbash 1) Stopping a Docker container by ID If you need to stop the container, run docker stop container id.If you need to to attach to a shell within the running container, run docker attach container id.![]() To view the status of the docker daemon execute sudo status docker You can then stop the Docker daemon by using sudo stop docker 3) Stopping multiple containers In this section we will see how to stop multiple containers in a system. There may arise situations where you may be required to stop all running containers either due to server overload, security breaches or good old maintenance. The easiest way will be by running docker kill (docker ps -q) 4) Removing containers Once docker containers are stopped you may need to delete docker images. One thing most system administrators may find very annoying is all unused containers and images taking up precious space. It would have been easier if there was a docker cleanup command to do the job. This will show you every image, including intermediate image layers. When youve located the images you want to delete, you can pass their ID or tag to docker rmi: docker images -a Remove: docker rmi imageone imagetwo Remove dangling images Docker images consist of multiple layers. Dangling images are layers that have no relationship to any tagged images. They can be located by adding the filter flag, -f with a value of danglingtrue to the docker images command. When youre sure you want to delete them, you can add the -q flag, then pass their ID to docker rmi: docker rmi (docker images -f danglingtrue -q) Removing images according to a pattern You can find all the images that match a pattern using a combination of docker images and grep. Once youre satisfied, you can delete them by using awk to pass the IDs to docker rmi. Note that these utilities are not supplied by Docker and are not necessarily available on all systems: docker images grep pattern awk print 1 xargs docker rm Removing Volumes Use the docker volume ls command to locate the volume name or names you wish to delete. Then you can remove one or more volumes with the docker volume rm command: docker volume rm volumename volumename Remove a container and its volume If you created an unnamed volume, it can be deleted at the same time as the container with the -v flag. When the container is successfully removed, its ID is displayed. Remove: docker rm -v containername Conclusion This article covers the fundamentals of stopping and removing docker images, containers and volumes. There are many other combinations and flags which can be used in each. For more comprehensive list, please review the docker documentation.
