How to Stop All Docker Containers?

To stop all running Docker containers, you can simply use the following command:

docker stop $(docker container ls -q)

This command does the following:

• docker container ls -q returns the list of ids of all running containers;
• docker stop attempts to trigger a graceful termination of the containers (by sending the SIGTERM signal to the main process inside the container).

You can also use docker ps -q instead of docker container ls -q. However, the latter is the newer syntax and is more readable than the former.

You can also choose to immediately stop/kill all running containers by using the docker kill command instead of docker stop. Please note though that there are some subtle differences between the two commands.
