You have installed multiple Docker images and would like to clean them up using rmi command. So, you list all the images as:

~> docker images --no-trunc
REPOSITORY                 TAG                 IMAGE ID                                                           CREATED             VIRTUAL SIZE

Then try to remove the “arungupta/wildfly-centos” image as shown below, but get an error:

~> docker rmi e4f1dbdff18956621aa48a83e5b05df309ee002c3668fa452f1235465d881020
Error response from daemon: Conflict, cannot delete e4f1dbdff189 because the container bafc2b3327a4 is using it, use -f to force
2014/12/02 12:56:53 Error: failed to remove one or more images

So you follow the recommendation of using -f switch but get another error:

~> docker rmi -f e4f1dbdff18956621aa48a83e5b05df309ee002c3668fa452f1235465d881020
Error response from daemon: No such id: c345720579e024df4f6d28d2062fda64b7743f7dbb214136d4d2285bc3afc95b
2014/12/02 12:56:55 Error: failed to remove one or more images

What do you do ?

This message indicates that the image is used by one of the containers and that’s why could not be removed. The error message is very ambiguous and a #9458 has been filed for the same.

In the meanwhile, an easy way to solve this is to list all the containers as shown:

CONTAINER ID        IMAGE                             COMMAND                CREATED             STATUS                      PORTS                NAMES

There are lots of containers that are using “arungupta/wildfly-centos” image but none of them seem to be running. If there are any containers that are running then you need to stop them as:

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

Remove the containers that are using this image as:

docker ps -a | grep arungupta/wildfly-centos | awk '{print $1}' | xargs docker rm
bafc2b3327a4
bfe71d92a612
e1c0965d202c
ff10b83d6c17
b2774b17460c
2d64f4eb8fb9
ac6f29b92c7a
31b9c4df0633

The criteria here is specified as a grep pattern.

docker ps command has other options to specify criteria as well such as only the latest created containers or containers in a particular status. For example, containers that exited with status -1 can be seen as:

~> docker ps -a -f "exited=-1"
CONTAINER ID        IMAGE                   COMMAND                CREATED             STATUS                       PORTS               NAMES
68aca76aa690        wildfly-centos:latest   "/opt/jboss/wildfly/   39 minutes ago      Exited (-1) 37 minutes ago                       insane_yonath

All running containers, as opposed to meeting a specific criteria, can be removed as:

docker rm $(docker ps -aq)

And now the image can be easily removed as

~> docker rmi e4f1dbdff189
Untagged: arungupta/wildfly-centos:latest
Deleted: e4f1dbdff18956621aa48a83e5b05df309ee002c3668fa452f1235465d881020
Deleted: ad2899e176a2e73acbcf61909426786eaa195fcea7fb0aa27061431a3aae6633

Just like removing all containers, all images can be removed as:

docker rmi $(docker images -q)

Enjoy!
