The following commands can be used to clean up a Docker host. This could be useful if you have been learning about Docker and want to get your lab hosts back to a vanilla state. They could of course work in production but please use the commands with caution.
Remove all services
docker service rm $(docker service ls -q)
This command queries Docker for a list of services and pipes the output to the docker service rm command. You could of course use it with a single service reference, for example:
docker service rm service name/id
Remove all containers
docker ps -aq
Use the ps -aq command to find a list of all the containers running on a Docker host.
docker stop $(docker ps -aq)
The first step is to use docker stop and pipe the output of docker ps -aq to force all running containers on the system to stop.
docker rm $(docker ps -aq)
The last step to actually rm the containers from the host, again pipe ps -aq into the docker rm command to achieve this.
Remove all images
docker rmi $(docker images -q)
This command removes all the images from the Docker host.
docker image prune
This command will remove all images which are not associated with a running or stopped container. Obviously if you have rm'd all the images this command is not needed. But its a good maintenance exercise to complete on a production host when optimsing disk space.
