Delete from registry

[msvticket]

Description

We primarily use docker with feature branches and when the feature branch is finished we want the corresponding images to be deleted from our registry. So we would like a goal like docker:registry-delete.

This cannot be performed by this plugin easily.

The problem is, that d-m-p only talks with the Docker daemon, never directly with the Docker registry. And unfortunately the Docker daemon doesn't provide an API method for removing an image from a registry (it supports e.g. pulling from a registry, where the client (d-m-p) calls the Docker daemon which in turn calls the registry).

For implementing this feature one would need to add a whole can of worms like managing authentication against a registry directly, cert handling, ....

So I'm afraid this is out of scope for this plugin. However, if the Docker API would support image removal from a registry, this feature could be considered to be included. Maybe you open an issue over there ?
