docker ps - show image ID instead of name

Question

I display running containers using docker ps command. There is an IMAGE column that shows name of the image that each container was create

Answer 1

I found that docker inspect <container-id> can be used for this purpose. It displays an image field containing full hash.

Answer 2

You can pass multiple container-ids to the docker inspect command and then use the --format to only get the values that you want.

docker inspect --format='{{.Id}} {{.Name}} {{.Image}}' $(docker ps -aq)

This will give you a list of the docker container Ids, names and image IDs that are being used for all of your containers.

asdf1234 /mydockercontainer sha256:abcd1234
