I had a container that I published and exported as an Image tarball.
Now I use that Image tarball to launch containers on several systems.
Recently I had to add some packages into my Image so I went back to the first container and then added packages to it and then re-published and exported it as a new Image tarball.
I then copied the new tarball to other system that had the older copy of the image. I tried importing the tarball with the same alias name thinking that it will update the existing image, but it generated the following error:
Error: Image with same fingerprint already exists
Is there a way to upgrade images? Or do I need to delete older images always to get the latest ones in use?
Because there could be a case where I have a container running with older image and I don’t want to delete that older container but rather upgrade the image so that the new containers can take advantage of the upgraded features in my image.
