How to remove all Docker containers

Question

I want to remove all of my docker containers at once. I tried to use $ docker rm [container_id] to do so, but it removed only one container, not all.

Is there any way to remove all docker containers using one single line of code?

Answer 1

As from Docker 1.13.0 --- Docker API 1.25:

docker container prune

Output:

WARNING! This will remove all stopped containers.
Are you sure you want to continue? [y/N] y

There is docker versioning matrix for better understanding docker versions (current is Docker 17.12 --- Docker API 1.35)
