Users are required to authenticate to the system registry before they can perform "push" or "pull" operations. Use the following steps to setup authentication.
Login to the Web Console
Click My Tools, API & Registry Keys
Click Manage Keys and then New Registry Key
Important
Make a note of the "key", "secret", and "label". The secret will not be displayed to you again.
The integrated system registry uses Oauth2 Token Authentication for authenticating docker clients. It redirects users automatically to a standalone Oauth service that authenticates docker clients and uses provided credentials in docker login to authenticate and authorize the request for a resource on the registry. For successful requests, a bearer token is returned, which is used by docker client to access a resource on the registry.
