Remove Repository
A repository can be removed using the Repositories, Projects and Tags Explorer. When a repository is removed, all images/tags are removed. Any sub-projects are also removed.
Repository removal is a background process which may take a while depending on the number of images and sub-projects being removed. While a repository is being removed, it may still be displayed when using the Repositories, Projects and Tags Explorer. In this case, "(deleting...)" is shown next to the repository name.
