  • If you have many port mappings, docker ps output becomes pretty illegible. The ~120 char one-liner changes the output into a more readable list of container! Show Sample Output

    docker ps | perl -ple "s/\$/\n\n/g;s/\s{2,}/\n/g;s/(Up)/\\e\[32m\$1\\e\[0m/g;s/(Down)/\\e\[31m\\e\[5m\$1\\e\[25m\\e\[0m/g;s/^([^\n]+)/\\e\[1m\$1\\e\[0m/g;s/(\w+?)$/\\e\[4m\$1\\e\[24m/g" | more

  • Useful if your Docker host starts running out of disk space due to Docker debris. You should start by running "sudo docker ps" in order to check that all required containers are in fact running, and fix any that aren't before proceeding to the main event! "sudo docker rm $(sudo docker ps -q -f status=exited)" removes all containers which are no longer running. "sudo docker rmi $(sudo docker images -q -f dangling=true)" removes all Docker images not required for currently running containers.

    sudo docker rm $(sudo docker ps -q -f status=exited); sudo docker rmi $(sudo docker images -q -f dangling=true)
