Note: In order to run the docker command line tool without the sudo command, you need to add a user to docker group, for instance. To prune volumes, simply add the -volumes flag to the below command as shown. By default, volumes are not removed, to prevent vital data from being deleted if there is currently no container using the volume. You can delete all dangling and unreferenced data such as containers stopped, images without containers, with this single command. How to Remove Unused or Dangling Images, Containers, Volumes, and Networks To remove all unused local volumes, run the following command. $ docker volume rm $(docker volume ls -q -filter dangling=true)

To remove dangling volumes, use the following command. Use the -f flag to force the removal of one or more volumes. $ docker volume rm volume_ID1 volume_ID2 #remove multiple volumes $ docker volume rm volume_ID #remove a single volume To remove one or more volumes, use the following command (note that you can’t remove a volume that is in use by a container). $ docker container prune #interactively remove all stopped containersĪs before, begin by listing all docker volumes on your system with the volume management command as shown. $ docker stop $(docker ps -a -q) #stop all containers To stop and remove all containers, use the following commands.

$ docker rm $(docker ps -qa -filter "status=exited") For example to remove all exited containers, use this command. You can remove containers using filters as well. You can also force-remove a container while it is running by adding the -force or -f flag, this will send it a SIGKILL signal as shown. If a container is running, you can first stop it and remove it as shown. $ docker rm 0fd99ee0cb61 0fd99ee0cb61 #remove multiple containers $ docker rm 0fd99ee0cb61 #remove a single container Once you have identified the container (s) you want to delete, you can remove them using their ID, for example. You can start by listing all docker containers on your system using following command. To remove all not associated with any container, use the following command.

$ docker rmi $(docker images -q -f dangling=true) $ docker image prune #interactively remove dangling images To remove all dangling images, allowing you to reclaim wasted disk space, use any of these commands. You can list dangling images (untagged images) using the -f filter flag as shown. $ docker rmi d65c4d6a3580 #remove a single image You can remove one or more old or unused Docker images using the image ID, for example (where d65c4d6a3580 is the image ID). They no longer have any relationship to any tagged images they are not useful anymore and only consume disk space. Looking at the output in the screenshot that follows, we have some images without a tag (showing instead), these are referred to as “ dangling images”. $ docker image #list the most recently created images How to Remove Docker Imagesīefore you remove any docker images, you can list all existing images on your system with the image management command.

We have already covered a series on Docker, that explains how to install Docker, run applications into containers and automatically build docker images with dockerfile. A container image is a self-contained, executable package of an application that includes everything needed to run it: code, runtime, system tools and libraries, as well as configurations. It is being widely adopted by IT and cloud companies out there, to easily to create, deploy, and run applications.Ī container is a technology for visualizing operating systems, that enables an application to be packaged with everything needed to run it, allowing it to run independently from the operating system. Docker is an open-source, powerful, secure, reliable and efficient container platform that enables realistic independence between applications and infrastructure.
