Question: I was unable to find resources to understand how Docker Hub images can be managed.

I have an image tagged with V0.0.1 and built a new one tagged V0.0.2. Now I want to remove the V0.0.1 image as the new version is built differently and I don't want users to pull the old image.

Answer: 
I've finally found how to do it in 2020!

You can't remove a tag from the "Tags" page right now but there is still a way:

1. Go to the image page on Dockerhub
2. Click on "Manage repository"
3. Click on "See all" under "Tags and Scans"
4. Now you can check the tags and use the action "Delete"
In a previous version of the Hub, you could do this via the "Tags" tab, which showed a little 'x' that you could click to delete the tag. In the new version of the Hub, this seems to have gone. I can only assume the functionality will return at some stage.

The relevant issue seems to be <https://github.com/docker/hub-feedback/issues/68>.

At the moment, the only workarounds I can see are:

* Delete the repository and recreate it, pushing just the tags you want to keep
* Contact Docker support and ask them to manually remove the unwanted tags
