How to use docker images filter

Question

I can write

docker images --filter \"dangling=true\"

What other filters can I use?

I can use something like this?

Answer 1

FYI, without filter, but for delete all images when you use as testing or learning,

docker image rm -f $(docker image ls)

Greetings.

Answer 2

There's another example, works with version 17.09++:

sudo docker rmi $(sudo docker images -f=reference="registry.gitlab.com/example-app" -f "dangling=true" -q)

Explanation:

• reference - we are referencing images by repository name;
• dangling=true - we are removing untagged images;
• -q - means quiet, showing only numeric IDs of images, instead of a whole line.

This command removes all images that have a repository name "registry.gitlab.com/example-app" and untagged (have <none> in a tag column)

Docker v1.13.0 supports the following conditions:

  -f, --filter value    Filter output based on conditions provided (default [])
                        - dangling=(true|false)
                        - label=<key> or label=<key>=<value>
                        - before=(<image-name>[:tag]|<image-id>|<image@digest>)
                        - since=(<image-name>[:tag]|<image-id>|<image@digest>)
                        - reference=(pattern of an image reference)

Or use grep to filter images by some value:

$ docker images | grep somevalue

You can also use the REPOSITORY argument to docker images to filter the images.

For example, suppose we have the images:

$ docker images
REPOSITORY           TAG          IMAGE ID         CREATED         SIZE
local-foo            latest       17864104b328     2 months ago    100 MB
example.com/bar      latest       b94c37de2801     9 months ago    285 MB
example.com/baz      latest       a004e3ac682c     2 years ago     221 MB

We can explicitly filter for all images with a given name:

$ docker images example.com/bar
REPOSITORY           TAG          IMAGE ID         CREATED         SIZE
example.com/bar      latest       b94c37de2801     9 months ago    285 MB

Docker also supports globbing:

$ docker images "example.com/*"
REPOSITORY           TAG          IMAGE ID         CREATED         SIZE
example.com/bar      latest       b94c37de2801     9 months ago    285 MB
example.com/baz      latest       a004e3ac682c     2 years ago     221 MB

Answer 5

In Docker v1.7:

The currently supported filters are:

• dangling (boolean - true or false)
• label (label=<key> or label=<key>=<value>)

Answer 6

sudo docker images --filter "running=false"

For cleaning up old stopped containers you can use:
docker container prune

To remove untagged images you can use:
docker image prune
