This post tells you how to delete a docker image with dependent images.
Problem Description
When trying docker rmi a12345678901, an error occurs as below.
1 | Error response from daemon: conflict: unable to delete a12345678901 (cannot be forced) - image has dependent child images |
Even if I add the flag -f, it also doesn’t work.
Root Cause
There are some dependent images so you cannot delete the image.
Solution
Remove unnecessary images.
1 | docker rmi $(docker images --filter "dangling=true" -q --no-trunc) |
And then delete the image.
1 | docker rmi a12345678901 |
