Define roles with authorized API operations

Estimated reading time: 4 minutes

This topic applies to Docker Enterprise.

The Docker Enterprise platform business, including products, customers, and employees, has been acquired by Mirantis, inc., effective 13-November-2019. For more information on the acquisition and how it may affect you and your business, refer to the Docker Enterprise Customer FAQ.

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

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:

Built-in 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.

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. Enter the role name on the Details page.
  4. Click Operations. All available API operations are displayed. See Swarm operations roles for a description of the available API operations.
  5. Select the permitted operations per resource type.
  6. Click Create.

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.

Operation Command Description
Config docker config Manage Docker configurations. See child commands for specific examples.
Container docker container Manage containers. See child commands for more information.
Container docker container create Create a new container. See extended description and examples for more information.
Container docker create [OPTIONS] IMAGE [COMMAND] [ARG...] Create new containers. See extended description and examples for more information.
Container docker update [OPTIONS] CONTAINER [CONTAINER...] Update configuration of one or more containers. Using this command can also prevent containers from consuming too many resources from their Docker host. See extended description and examples for more information.
Container docker rm [OPTIONS] CONTAINER [CONTAINER...] Remove one or more containers. See options and examples for more information.
Image docker image COMMAND Manage images. See child commands for examples.
Image docker image remove Remove one or more images. See child commands for examples.
Network docker network Manage networks. You can use child commands to create, inspect, list, remove, prune, connect, and disconnect networks.
Node docker node COMMAND Manage Swarm nodes. See child commands for examples.
Secret docker secret COMMAND Manage Docker secrets. See child commands for sample usage and options.
Service docker service COMMAND Manage services. See child commands for sample usage and options.
Volume docker volume create [OPTIONS] [VOLUME] Create a new volume that containers can consume and store data in. See examples for more information.
Volume docker volume rm [OPTIONS] VOLUME [VOLUME...] Remove one or more volumes. Users cannot remove a volume that is in use by a container. See related commands for more information.
