Getting following error with all the commands apart from ImagePull and ImagePush at present. investigating it further

Steps to fix this:

1] use cli.ImageTag in ImagePush function first and then
2] use cli.ImagePush

but the issue is I am getting above error with a simple cli.ImageTag call in ocibuilder repo. It works fine on my machine in another sample repository

[artbegolli]

What error is being thrown with ImageTag?

[AniketKul]

@artbegolli - similar to what I had posted earlier. ImageRemove that we have in our code also throws similar error.

Add ImageTag to the mock test function in docker_test.go

[AniketKul]

[AniketKul]

this is almost done. just need to regenerate clientset to fix some unwanted code in clientset. working on it
