Docker registry

Recon

By default, docker registry run on port 5000. The first step to do is to know if the registry need authentication token or not. You can do this by sending a request to the registry.

curl -I http://<HOST>:5000/v2/

Get authentication token

With the header www-authenticate you can know if the registry need authentication token or not.

Example of response:

Www-Authenticate: Bearer realm="http://<HOST>:5001/",service="Docker registry",error="invalid_token"

From this response you can try to get a token, the realm is the url to get the token.

Examples of requests:

# Try to get only access on catalog
curl http://<REALM_URL>/auth?scope=registry:catalog:*&service=<NAME_OF_SERVICE>
# Try to get only pull,push right on an image
curl http://<REALM_URL>/auth?scope=repository:<IMAGE_NAME>:*&service=<NAME_OF_SERVICE>
# Try to get only pull right on an image
curl http://<REALM_URL>/auth?scope=repository:<IMAGE_NAME>:pull&service=<NAME_OF_SERVICE>

Get all images names

You can get all images names by sending a request to the registry with the authentication token.

curl -H "Authorization: Bearer eyJ......" http://<HOST>:5000/v2/_catalog

Get all tags for an image

You can get all tags for an image by sending a request to the registry with the authentication token.

curl -H "Authorization: Bearer eyJ......" http://<HOST>:5000/v2/<IMAGE>/tags/list

Get image manifest

You can get image manifest by sending a request to the registry with the authentication token.

curl -H "Authorization: Bearer eyJ......" http://<HOST>:5000/v2/<IMAGE>/manifests/<TAG>

Get image layer

curl  -H "Authorization: Bearer eyJ......" http://<HOST>:5000/v2/<IMAGE>/blobs/<LAYER>

Automated tools

You can also use an automated tool like DockerRegistryGrabber.
