Manage Harbor users and roles

Reviewed on October 2, 2026 · View on GitHub

The Container Registry (Harbor) managed service provides an administrator account at creation. For fine-grained access management, create additional users and configure permissions per project.

note

The Numspot API only allows you to manage the administrator password. Creating users and managing permissions is performed through the Harbor interface or the Harbor API.

Connect to Harbor

Before managing users, connect to the Harbor interface:

1. Retrieve the administrator password (see Retrieve the password) ;
2. Go to https://registry-{registryId}.hcp.cloudgouv-eu-west-1.numspot.com ;
3. Log in with admin and the password.

User types

System administrator

• Full access to all functions ;
• Management of users, projects and system configuration ;
• Access to all projects.

Standard user

• Access to projects according to the permissions assigned ;
• Push/pull operations according to the role within the project.

Robot account

• User for automation (CI/CD, Kubernetes) ;
• Permissions defined per project ;
• Secret token instead of a password.

For more details on robot accounts, see Robot accounts.

Checking sensitive access

• Public projects: which projects are publicly accessible?
• Administrators: who has system admin rights?
• Active robot accounts: which robot accounts are in use?

Best practices

Principle of least privilege

• Grant the minimum permissions required ;
• Use the Guest role for read-only users ;
• Restrict the Admin and Master roles.

Project organization

Project type	Recommended permissions
Production	Restricted - Master/Admin only
Staging	Developer for the dev team
Public	Developer for push, public access for pull

Credential rotation

• Change user passwords regularly ;
• Refresh the secrets of robot accounts ;
• Revoke unused access.

Regular audit

• Monthly review of access to sensitive projects ;
• Deletion of inactive accounts ;
• Verification of expired robot accounts.

Limitations

Action	Support
Retrieve the admin password	Through the Numspot API
Create users	Through the Harbor UI or Harbor API
Manage permissions	Through the Harbor UI or Harbor API
Create projects	Through the Harbor UI or Harbor API
Configure quotas	Through the Harbor UI or Harbor API

tip

Automate user management with scripts that use the Harbor API. Integrate access management into your environment provisioning processes.
