There are certain things I find myself googling over and over again. How to stop all Docker containers is one of those things! Hopefully this post makes it just a bit easier to find.

TL;DR: How to Stop All Docker Containers

To stop all Docker containers, simply run the following command in your terminal:

docker kill $(docker ps -q)

How It Works

The docker ps command will list all running containers. The -q flag will only list the IDs for those containers. Once we have the list of all container IDs, we can simply run the docker kill command, passing all those IDs, and they’ll all be stopped!

How to Remove All Docker Containers

If you don’t just want to stop containers and you’d like to go a step further and remove them, simply run the following command:

docker rm $(docker ps -a -q)

How It Works

We already know that docker ps -q will list all running container IDs. What is the -a flag? Well that will return all containers, not just the running ones. Therefore, this comman will remove all containers (including both running and stopped containers).

How To Remove All Docker Images

To remove all Docker images, run this command:

docker rmi $(docker images -q)

How It Works

docker images -q will list all image IDs. We pass these IDs to docker rmi (which stands for remove images) and we therefore remove all the images.
