Find the docker containers using an image?

Question

If I have the ID of an image how can I find out which containers are using this image? When removing an image that is still used you get an error message:

$ docker rmi 77b0318b76b3
Error response from daemon: Conflict, cannot delete 77b0318b76b3 because the container 21ee2cbc7cec is using it, use -f to force

But how could I find this out in an automated way without trying to remove it?

I was trying something along the lines of: docker ps | tail -n +2 | awk '{print $2;}' | while read image; do docker history $image | awk '{print $1;}'| tail -n +2 ; done | sort| uniq I thought this would have listed all images referenced by the currently running containers, but it doesn't seem to. — Matthew Buckett

if you want to list the images of the active containers docker inspect -f '{{ .Config.Image}}' $(docker ps -q) and for all the containers docker inspect -f '{{ .Config.Image}}' $(docker ps -qa) — user2915097

This will list all containers using your $IMAGE_ID.

$IMAGE_ID can be 77b0318b76b3 or namespace/repo:tag.

E.g.: $IMAGE_ID="77b0318b76b3"

docker container ls --all --filter=ancestor=$IMAGE_ID --format "{{.ID}}"

Exactly what's needed and w/o resorting to parsing of textual stdout output. :thumbs_up:

You can try this:

docker ps -a | grep `docker images | grep IMAGE_ID | awk '{print $1":"$2}'` | awk '{print $1}'

With docker ps -a you get the list of all the containers including the ones you are interested in.
The problem is that you have the IMAGE NAME there but you need the IMAGE ID.
You can use docker images to get the IMAGE ID for a given IMAGE NAME and that is what you use in your grep to filter by your IMAGE ID.
Finally you get the first column to show only the CONTAINER IDs.

Example:

docker ps -a \
 | grep `docker images | grep 3a041c1b0a05 | awk '{print $1":"$2}'` \
 | awk '{print $1}'

Output:

4d6fb8a7149f
2baa726b1aa5

Hope this helps.

f you want to list the images of the active containers docker inspect -f '{{ .Config.Image}}' $(docker ps -q) and for all the containers docker inspect -f '{{ .Config.Image}}' $(docker ps -qa)

If the image has a nice name it will just output the name of the image, not the ID.

So let's print the Image name and the ID docker inspect -f '{{ .Config.Image}} {{ .State.Pid}}' $(docker ps -q) Is that what you want?
