kill all docker containers at once...

docker_kill.sh

docker ps | awk {' print $1 '} | tail -n+2 > tmp.txt; for line in $(cat tmp.txt); do docker kill $line; done; rm tmp.txt

If you want to be a hipster and stop all running containers using the management commands than use this.

docker container stop $(docker container ls -q)

docker rm -f $(docker ps -a -q)

@eenchev completely agree. When I wrote this like six years ago, I had no idea what I was doing. 😅

...and some would argue that not much has changed!

These days I use something closer to docker ps -qa | xargs docker stop.

docker container stop $(docker container ls -q)

thanks, worked like a charm !!

All didn't work for me

I used docker stop $(docker ps -a -q)

All did n't work for me

I used docker stop $(docker ps -a -q)

docker kill, not stop

doing it like this:

sudo docker kill $(sudo docker ps -q)

Why not something like docker stopall ?

docker kill $(sudo docker ps -q)

This is great, thanks @webdev23 !
