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: 
1. Open hub.docker.com and sign in.
2. Click on Details for your image.
3. Click on Tags.
4. Click on the delete icon (bin) on the right.

Unfortunately, even if you delete the only tag for that image, the image will still be listed in your account/repository. However, anyone who tries `docker pull` on that image will get an error message.
I guess the only way to delete the image entirely is to delete the account (and all its images).
People have been saying that the feature to delete specific tags from the Docker Hub UI has been removed, but this is inaccurate, it's just a bit more hidden.

1. go to your repository in Docker Hub
2. go to "Tags"
3. at the bottom, click the "see all" link
4. press the "..." menu to the right of the tag you want to delete
5. press "delete"

This will allow you to delete a specific tag on the new version of Docker Hub.
