In the new Concourse 5.0.0 version, a new resource was released to track and upload Docker images to a registry, the registry-image-resource. This new resource is intended to replace the current docker-image-resource, as it’s more lightweight and simpler. Concourse announced that they intend to deprecate the current docker-image-resource in the future.
The only caveat is that the new registry-image-resource doesn’t build images, so you need to do that a task before the put step. We documented on how you can do this in our documentation
You can already take action by making the required changes to your pipelines so you are ready when it gets removed from Concourse.
PS: the new resource is a lot faster than the old one ;-).
