Docker pull - force download

Question

Is there a possibility to force pull of docker image?

I have redeployed docker image to another repository, but when I invoke

docker pull anotherrepo:port/my/image

nothing gets downloaded, instead I get info:

Digest: sha256:somehash

and that image is up to date.

docker rm/rmi doesn't work because the image is downloaded from originalrepo:port/my/image and I don't want to stop/delete it onyl for test purposes.

Is there possible to force pull to check if the image is correctly pushed?

Answer 1

The following should work. You add a temporary tag to avoid deletion of the image, delete the original tag and then pull:

docker tag "$originalTag" "tmpTag"
docker rmi "$originalTag"
docker pull "$originalTag"
docker rmi "tmpTag"
