Pentester-focused Docker registry tool to enumerate and pull images

go-pillage-registries

This project takes a Docker registry and pillages the manifest and configuration for each image in its catalog.

It uses Google's crane command's package, which should follow docker's keychain semantics. If you would like to override this, just change authn.DefaultKeychain as described in the https://github.com/google/go-containerregistry/tree/master/pkg/authn/k8schain

Install:

git clone https://github.com/nccgroup/go-pillage-registries.git

cd go-pillage-registries
