Permission levels

Docker Universal Control Plane has two types of users: administrators and regular users. Administrators can make changes to the UCP cluster, while regular users have permissions that range from no access to full control over volumes, networks, images, and containers.

Administrator users

In Docker UCP, only users with administrator privileges can make changes to cluster settings. This includes:

• Managing user and team permissions,
• Managing cluster configurations like adding and removing nodes to the cluster.

Default permission levels

Regular users can’t change cluster settings, and they are assigned with a default permission level.

The default permission level specify the resources a user access or edit. You can choose from four permission levels that range from no access to full control over the resources.

If a user has Restricted Control or Full Control default permissions, they can create resources without labels, and only the user and Admins can see and access the resources. Default permissions also affect ability for a user to access things that can’t have labels, images and nodes.

Team permission levels

Teams and labels give the administrator fine-grained control over permissions. Each team can have multiple labels. Each label has a key of com.docker.ucp.access.label. The label is then applied to the containers, services, networks, secrets, and volumes. Labels are not currently available for nodes and images. DTR has its own permissions.

There are four permission levels:
