Remove container images from review apps from the container registry

Problem to solve

When using AutoDevops and review apps, a container is build for each feature branch. After the feature branch is merged and removed the container registry still has the containers from this feature branch. Which will result eventually in an overloaded repository with containers.

Further details

Goal here is to keep the container registry clean after removal of the feature branch.

Proposal

Two options:

1. On a merge request when Remove source branch is checked also remove the related container images in the container registry
2. On a merge request add a extra option to check, whether to remove the container images from the registry or not

What does success look like, and how can we measure that?

You can measure the success by checking the container registry and see if the images are removed.
