How to remove multiple Docker images

When I’m playing with Docker for a new project I usually end up having dozens or even more of <none> images:

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
<none>              <none>              affd29c496e2        3 seconds ago       525.5 MB
<none>              <none>              aeffd5bae1bb        27 seconds ago      526.3 MB
<none>              <none>              55b57705daa5        2 minutes ago       526.3 MB
mongo               3                   e047731b9266        4 days ago          261.3 MB

It’s pretty annoying to remove images one by one and copy/paste their IDs, so I came up with simple one line command to remove all the <none>:

$ docker rmi -f $(docker images | grep "<none>" | awk '{print $3}')

And as you can see no more <none> images:

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
mongo               3                   e047731b9266        4 days ago          261.3 MB
gliderlabs/alpine   3.2                 2cc966a5578a        3 weeks ago         5.25 MB
golang              1.4                 c5a2538d92ec        4 weeks ago         517.3 MB

You can also change filter criteria for grep command to what ever you want to remove.

Or even go further and create an alias in your ~/.bash_profile:

dockerRemoveImagesWithCriteria() {
    if [[ -z "$1" ]]; then
        $1="<none>"
    fi

    count=$(docker images | grep "$1" | wc -l)

    if [[ "$count" -eq 0 ]]; then
        echo "No docker images found for criteria '$1'"
    else
       docker rmi -f $(docker images | grep "$1" | awk '{print $3}')
    fi
}

alias docker-remove=dockerRemoveImagesWithCriteria

…do not forget to source your ~/.bash_profile :

$ source ~/.bash_profile

…and call it from the terminal:

$ docker-remove none
