How to authorize a docker repository

Docker repository authorization can be implemented through the ACL of Docker Hub or custom authentication. ACL allows specifying access to users or teams, while custom authentication provides finer granular control, such as username/password, token, or SSO. Authorized permissions include read, write, and administrative access, and should be assigned based on user type, mirror sensitivity, and required management levels.

How to authorize a Docker repository?

Authorizing a Docker repository involves granting users permissions to access and manage repository. This can be done by using the Docker Hub's access control list (ACL) or setting up custom authentication.

Docker Hub ACL

Docker Hub provides an ACL system that allows you to specify specific user and team permissions for your repository. To use ACL:

1. Log in to Docker Hub.
2. Navigate to your warehouse.
3. Click the Settings tab.
4. In the Access Control section, add users or teams and assign them the permissions they need.

Custom authentication

If you want more fine-grained control, you can set up custom authentication, for example:

• Username/password authentication: Use traditional username and password for authentication.
• Token Authentication: Use an authorization token to authenticate.
• Single Sign-On (SSO): Authenticate using an external identity provider.

To set up custom authentication, you need to use the Docker API or the Docker Registry v2 API. For more information, see the official Docker documentation.

Specific permissions

Docker repository permissions can be divided into the following levels:

• Read access: Allows the user to pull the image.
• Write access permission: Allows users to push images.
• Administrative access: Allows users to manage repositories, such as adding and deleting users.

The following factors should be considered when assigning permissions:

• The type of user that needs to access the repository.
• Sensitivity of mirroring in warehouses.
• The level of management required.

By carefully managing authorization for Docker repositories, you can ensure that only the appropriate users can access and operate your images.
