I created a local docker registry and then pull some of my docker images from docker hub and then push them to the local registry. Now I want to remove my local images. But the
Here is one way :
Repository and tag data can be provided to "docker rmi" command to remove image if images id are same.
command
docker rmi [repository_name1]:[tag1] [repository_name2]:[tag2]
example
docker rmi test-nginx:latest ubuntu:latest
Note : one needs to name and tag the image appropriately to use the above command effectively for requirement mentioned in the question.
Refer Docker docs for "docker rmi" command help : here
Remove it by id and use -f
flag:
$ docker rmi -f fd484f19954f
Untagged: test1:latest
Untagged: test2:latest
Deleted: fd484f19954f4920da7ff372b5067f5b7ddb2fd3830cecd17b96ea9e286ba5b8
These are not multiple images with same id. This is actually one image that is referenced in multiple repositories (i.e. given multiple names/tags). This scenario is described exactly in rmi command documentation
You can remove an image using its short or long ID, its tag, or its digest. If an image has one or more tag referencing it, you must remove all of them before the image is removed. Digest references are removed automatically when an image is removed by tag.
Given,
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test1 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB)
test2 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB)
You can, as an alternative to the short answer above, remove tags one by one (the last tag will actually remove the image too):
$ docker rmi test1:latest
Untagged: test1:latest
$ docker rmi test2:latest
Untagged: test2:latest
