-Seeing all created containers is as simple as docker ps -a.
-To remove all existing containers (not images!) run docker rm $(docker ps -aq)
-===== Removing images according to a pattern =====
-You can find all the images that match a pattern using a combination of docker images and grep.  Once you're satisfied, you can delete them by using awk to pass the IDs to docker rmi.  Note that these utilities are not supplied by Docker and are not necessarily available on all systems:
-To find the images:
-<code bash>
-docker ps -a |  grep "pattern"
-</code>
-To remove the images:
-<code bash>
-docker images | grep "pattern" | awk '{print $1}' | xargs docker rm
