Stopping Docker containers by image name - Ubuntu

Question

On Ubuntu 14.04 (Trusty Tahr) I\'m looking for a way to stop a running container and the only information I have is the image name that was used in the Docker run comma

Answer 1

If you want to prefer a simple AWK approach, here Is my take:

docker rm -f $(docker ps | awk '{ if($2 == "") { print $NF}}')

$(docker ps | awk '{ if($2 == "") { print $NF}}') - prints the docker container names based on input image

docker ps - list all containers

awk '{ if($2 == "") { print $NF}}' - The second parsed column of docker ps gives the image name. Comparing it with your image name will execute print $NF which prints the container name.

docker rm -f removes the containers

For example, removing all running containers of ubuntu image, can be done simply as:

docker rm -f $(docker ps | awk '{ if($2 == "ubuntu:latest") { print $NF}}')

PS: Remember to include the image tag in AWK, since it's a equal comparator.
