Find and remove docker image

#docker #devops

Docker documentation mentions removing all stopped containers using command:

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

but at times we want to first find existing containers and then remove them. This can be achieved when you filter and limit the result of docker ps command.

Limit the result of `docker ps`

You can either use the --filter, --last or --latest options or pipe the result of docker ps to grep command to filter the results for matching PATTERN.

Here is an example using grep:

$ docker ps -a | grep PATTERN | \
  awk '{print $1}' | xargs -r docker rm

where the PATTERN could be part of container name, image name or any other details present in the result of docker ps command like mapped port number.

Feel free to share your feedback/opinion in comments.
