Configuring container registry authentication

The Janus controller supports authentication to private container registries using tokens passed via the X-Registry-Auth HTTP header. The tokens are in the form of a base64 encoded dictionary containing the following attributes:

{ "username": "",
  "password": "",
  "serveraddress": ""
}

As an example, Harbor registries allow for the creation of robot accounts with secret keys. Using one of these robot accounts, a valid token for Janus/Portainer can be created as follows:

echo '{"username": "robot+dtnaas+deployer", "password": "SECRET_KEY", "serveraddress": "wharf.es.net"}' | base64 -w 0

For a single authenticated registry, this token can be passed as an environment variable when launching the controller process. In a Janus controller Docker compose file, include the following:

   ...
   environment:
      - REGISTRY_AUTH=<TOKEN>
   ...

Within the Janus settings.py file is where the registry auth dictionary is maintained to map registry servers to authentication tokens. Additional registries with their associated auth tokens may be defined as needed.
