Docker remove TAG images

Question

root@server:~# docker images -a        
REPOSITORY              TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

I've tried the following:

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

And the following:

docker rmi $(docker images -f "dangling=true" -q)

Get the following error:

docker: "rmi" requires a minimum of 1 argument.
See 'docker rmi --help'.

Usage:  docker rmi [OPTIONS] IMAGE [IMAGE...]

Remove one or more images

Answer 1

The below command is working for me. this is just simple grep "" images and get the docker image id and removed all the images. Simple single command as it has to.

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

Answer 2

Just remove the images using their IDs:

# docker rmi 5e2dfc857e73 d053e988f23d ...

Answer 3

try

docker rmi -f $(docker images -a | awk 'NR> 1 || $2 = "<none>" {print $3}') , while there may be cleaner commands

Updated

Answer 4

docker rmi $(docker images -a -q)

Stated the following images where in use. I think this command gets rid of unwanted images.

Answer 5

You can try and list only untagged images (ones with no labels, or with label with no tag):

docker images -q -a | xargs docker inspect --format='{{.Id}}{{range $rt := .RepoTags}} {{$rt}} {{end}}'|grep -v ':'

However, some of those untagged images might be needed by others.

I prefer removing only dangling images:

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

As I mentioned for for docker 1.13+ in Sept. 2016 in "How to remove old and unused Docker images", you can also do the image prune command:

docker image prune

That being said, Janaka Bandara mentions in the comments:

This did not remove <none>-tagged images for me (e.g. foo/bar:<none>); I had to use docker images --digests and docker rmi foo/bar@<digest>

Janaka references "How to Remove a Signed Image with a Tag" from Paul V. Novarese:

# docker images
REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
pvnovarese/mprime        latest              459769dbc7a1        5 days ago          4.461 MB
pvnovarese/mprime        <none>              459769dbc7a1        5 days ago          4.461 MB

Diagnostic Steps

You can see the difference in these two entries if you use the --digests=true option (the untagged entry has the Docker Content Trust signature digest):

# docker images --digests=true
REPOSITORY               TAG                 DIGEST                                                                    IMAGE ID            CREATED             SIZE
pvnovarese/mprime        latest              <none>                                                                    459769dbc7a1        5 days ago          4.461 MB
pvnovarese/mprime        <none>              sha256:0b315a681a6b9f14f93ab34f3c744fd547bda30a03b55263d93861671fa33b00   459769dbc7a1        5 days ago     

Note that Paul also mentions moby issue 18892:

After pulling a signed image, there is an "extra" entry (with tag <none>) in "docker images" output.
This makes it difficult to rmi the image (you have to force it, or else first delete the properly-tagged entry, or delete by digest.

Answer 6

Its simple and clear,

Even I took 3 days to understand this simple and crisp error.

The docker image is not built successfully

Then I removed the 8th line from Dockerfile, it was signal success this time.

It says successfully tagged dem:expo, this line is imp during docker process.
