Define roles with authorized API operations

Define roles with authorized API operations

A role defines a set of API operations permitted against a resource set. You apply roles to users and teams by creating grants.

Diagram showing UCP permission levels

Some important rules regarding roles:

  • Roles are always enabled.
  • Roles can’t be edited. To edit a role, you must delete and recreate it.
  • Roles used within a grant can be deleted only after first deleting the grant.
  • Only administrators can create and delete roles.

Default roles

You can define custom roles or use the following built-in roles:

Role Description
None Users have no access to Swarm or Kubernetes resources. Maps to No Access role in UCP 2.1.x.
View Only Users can view resources but can’t create them.
Restricted Control Users can view and edit resources but can’t run a service or container in a way that affects the node where it’s running. Users cannot mount a node directory, exec into containers, or run containers in privileged mode or with additional kernel capabilities.
Scheduler Users can view nodes (worker and manager) and schedule (not view) workloads on these nodes. By default, all users are granted the Scheduler role against the /Shared collection. (To view workloads, users need permissions such as Container View).
Full Control Users can view and edit all granted resources. They can create containers without any restriction, but can’t see the containers of other users.

Create a custom role for Swarm

When creating custom roles to use with Swarm, the Roles page lists all default and custom roles applicable in the organization. To create custom roles for Kubernetes, see Configure native Kubernetes role-based access control.

You can give a role a global name, such as “Remove Images”, which might enable the Remove and Force Remove operations for images. You can apply a role with the same name to different resource sets.

  1. Click Roles under User Management.
  2. Click Create Role.
  3. Input the role name on the Details page.
  4. Click Operations. All available API operations are displayed.
  5. Select the permitted operations per resource type.

Swarm operations roles

This section describes the set of operations (calls) that can be executed to the Swarm resources. Be aware that each permission corresponds to a CLI command and enables the user to execute that command.

Some important rules regarding roles**:

  • Roles are always enabled.
  • Roles can’t be edited. To edit a role, you must delete and recreate it.
  • Roles used within a grant can be deleted only after first deleting the grant.
  • Only administrators can create and delete roles.
