Authentication and authorization in DTREstimated reading time: 1 minute
These are the docs for DTR version 2.2
To select a different version, use the selector below.
With DTR you get to control which users have access to your image repositories.
By default, anonymous users can only pull images from public repositories. They can’t create new repositories or push to existing ones. You can then grant permissions to enforce fine-grained access control to image repositories. For that:
Start by creating a user.
Users are shared across Docker Datacenter. When you create a new user in Docker Universal Control Plane, that user becomes available in DTR and vice versa. Registered users can create and manage their own repositories.
You can also integrate with an LDAP service to manage users from a single place.
Extend the permissions by adding the user to a team.
To extend a user’s permission and manage the user’s permissions over repositories, you add the user to a team. A team defines the permissions users have for a set of repositories.
Organizations and teams
When a user creates a repository, only that user can make changes to the repository settings, and push new images to it.
Organizations take permission management one step further, since they allow multiple users to own and manage a common set of repositories. This is useful when implementing team workflows. With organizations you can delegate the management of a set of repositories and user permissions to the organization administrators.
An organization owns a set of repositories, and defines a set of teams. With teams you can define fine-grained permissions that a team of user has for a set of repositories.
In this example, the ‘Whale’ organization has three repositories and two teams:
- Members of the blog team can only see and pull images from the whale/java repository,
- Members of the billing team can manage the whale/golang repository, and push and pull images from the whale/java repository.
