Docker: How to find the dependent child images?
Raw

Find the dependent child images on Docker

When you try to remove the docker image with the following command

docker rmi 6795374be8c1

Sometimes you might be facing below error:

Error response from daemon: conflict: unable to delete 6795374be8c1 (cannot be forced) - image has dependent child images

Below is the Docker command line used to find the dependent child images

Format:

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since= -q)

Example:

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since=6795374be8c1 -q)

Result:

sha256:1d1f94c972fc8d75a34135f9ff551617680c508f7ad17efda09048b4e805g1w3

Here sha256:1d1f94c972fc8d75a34135f9ff551617680c508f7ad17efda09048b4e805g1w3, the bold value is your dependent child image

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since=6795374be8c1 -q)
This will also return not dependent images, but that were created since specified one was. You have to additionally filter with parent id like here.
