Dangling resource are unused resources that are not related to any other active resource anymore.

Images

  • List all images: $ docker images -a
  • Remove all images: $ docker rmi $(docker images -a -q)
  • Remove specific images: $ docker rmi <image1> <image2>
  • List dangling images: $ docker images -f dangling=true
  • Remove dangling images: $ docker rmi $(docker images -f dangling=true -q)
  • List images according to pattern: $ docker ps -a | grep "pattern"
  • Remove images according to pattern: $ docker images | grep "pattern" | awk '{print $1}' | xargs docker rm

Containers

  • List all containers: $ docker ps -a
  • Stop all containers: $ docker stop $(docker ps -a -q)
  • Remove all containers: $ docker rm $(docker ps -a -q)
  • Remove specific containers: $ docker rm <container1> <container2>
  • List exited containers: $ docker ps -a -f status=exited
  • Remove exited containers: $ docker rm $(docker ps -a -f status=exited -q)

Multiple filters can be added to list and remove commands. For instance, to list container with status exited or created use docker ps -a -f status=exited -f status=created.

  • List containers according to pattern: $ docker ps -a | grep "pattern”
  • Remove containers according to pattern: $ docker ps -a | grep "pattern" | awk '{print $3}' | xargs docker rmi

Volumes

  • List all volumes: $ docker volume ls
  • Remove specific volumes: $ docker volume rm <volume1> <volume2>
  • List dangling volumes: $ docker volume ls -f dangling=true
  • Remove dangling volumes: $ docker volume rm $(docker volume ls -f dangling=true -q)
