Manage RBAC roles

This section includes instructions for how to view permissions associated with roles, create custom roles, and update and delete roles.

The following example includes the base64 username:password Basic Authorization. You cannot use authorization tokens in the request.

List permissions associated with roles

Use a GET command to see the actions and scopes associated with a role. For more information about seeing a list of permissions for each role, refer to Get a role.

To see the permissions associated with basic roles, refer to the following basic role UIDs:

Example request

Copy

curl --location --request GET '<grafana_url>/api/access-control/roles/qQui_LCMk' --header 'Authorization: Basic YWRtaW46cGFzc3dvcmQ='

Example response

Copy

}

Refer to the RBAC HTTP API for more details.

Create custom roles

This section shows you how to create a custom RBAC role using Grafana provisioning and the HTTP API.

Create a custom role when basic roles and fixed roles do not meet your permissions requirements.

Before you begin:

• Plan your RBAC rollout strategy.
• Determine which permissions you want to add to the custom role. To see a list of actions and scope, refer to RBAC permissions, actions, and scopes.
• Enable role provisioning.
• Ensure that you have permissions to create a custom role.
  • By default, the Grafana Admin role has permission to create custom roles.
  • A Grafana Admin can delegate the custom role privilege to another user by creating a custom role with the relevant permissions and adding the permissions:type:delegate scope.

Create custom roles using provisioning

File-based provisioning is one method you can use to create custom roles.

1. Open the YAML configuration file and locate the roles section.

2. Refer to the following table to add attributes and values.

1. Reload the provisioning configuration file.

   For more information about reloading the provisioning configuration at runtime, refer to Reload provisioning configurations.

The following example creates a local role:

yaml Copy

# config file version
apiVersion: 2

roles:
  - name: custom:users:writer
    description: 'List, create, or update other users.'
    version: 1
    orgId: 1
    permissions:
      - action: 'users:read'
        scope: 'global.users:*'
      - action: 'users:write'
        scope: 'global.users:*'
      - action: 'users:create'

The following example creates a hidden global role. The global: true option creates a global role, and the hidden: true option hides the role from the role picker.

yaml Copy

# config file version
apiVersion: 2

roles:
  - name: custom:users:writer
    description: 'List, create, or update other users.'
    version: 1
    global: true
    hidden: true
    permissions:
      - action: 'users:read'
        scope: 'global.users:*'
      - action: 'users:write'
        scope: 'global.users:*'
      - action: 'users:create'

The following example creates a global role based on other fixed roles. The from option contains the roles from which we want to copy permissions. The permission state: absent option can be used to specify permissions to exclude from the copy.

yaml Copy

# config file version
apiVersion: 2

roles:
  - name: custom:org.users:writer
    description: 'List and remove other users from the organization.'
    version: 1
    global: true
    from:
      - name: 'fixed:org.users:reader'
        global: true
      - name: 'fixed:org.users:writer'
        global: true
    permissions:
      - action: 'org.users:write'
        scope: 'users:*'
        state: 'absent'
      - action: 'org.users:add'
        scope: 'users:*'
        state: 'absent'

Create custom roles using the HTTP API

The following examples show you how to create a custom role using the Grafana HTTP API. For more information about the HTTP API, refer to Create a new custom role.

The following example creates a custom:users:admin role and assigns the users:create action to it.

Example request

Copy

curl --location --request POST '<grafana_url>/api/access-control/roles/' \
--header 'Authorization: Basic YWRtaW46cGFzc3dvcmQ=' \
--header 'Content-Type: application/json' \
--data-raw '{
    "version": 1,
    "uid": "jZrmlLCkGksdka",
    "name": "custom:users:admin",
    "displayName": "custom users admin",
    "description": "My custom role which gives users permissions to create users",
    "global": true,
    "permissions": [
        {
            "action": "users:create"
        }
    ]
}'

Example response

Copy

{
    "version": 1,
    "uid": "jZrmlLCkGksdka",
    "name": "custom:users:admin",
    "displayName": "custom users admin",
    "description": "My custom role which gives users permissions to create users",
    "global": true,
    "permissions": [
        {
            "action": "users:create"
            "updated": "2021-05-17T22:07:31.569936+02:00",
            "created": "2021-05-17T22:07:31.569935+02:00"
        }
    ],
    "updated": "2021-05-17T22:07:31.564403+02:00",
    "created": "2021-05-17T22:07:31.564403+02:00"
}

Refer to the RBAC HTTP API for more details.

Update basic role permissions

If the default basic role definitions do not meet your requirements, you can change their permissions.

Before you begin:

• Determine the permissions you want to add or remove from a basic role. For more information about the permissions associated with basic roles, refer to RBAC role definitions.

To change permissions from a basic role:

1. Open the YAML configuration file and locate the roles section.

2. Refer to the following table to add attributes and values.

   Attribute	Description
   name	The name of the basic role you want to update. You can specify a uid instead of a role name. The role name or the uid are required.
   orgId	Identifies the organization to which the role belongs. global can be used instead to specify it’s a global role.
   version	Identifies the version of the role, which prevents overwriting newer changes.
   from	List of roles from which to copy permissions.
   permissions > state	The state of the permission. You can set it to absent to ensure it exclusion from the copy list.

3. Reload the provisioning configuration file.

   For more information about reloading the provisioning configuration at runtime, refer to Reload provisioning configurations.

The following example modifies the Grafana Admin basic role permissions.

• Permissions to list, grant, and revoke roles to teams are removed.
• Permission to read and write Grafana folders is added.

yaml Copy

# config file version
apiVersion: 2

roles:
  - name: 'basic:grafana_admin'
    global: true
    version: 3
    from:
      - name: 'basic:grafana_admin'
        global: true
    permissions:
      # Permissions to remove
      - action: 'teams.roles:read'
        scope: 'teams:*'
        state: 'absent'
      - action: 'teams.roles:remove'
        scope: 'permissions:type:delegate'
        state: 'absent'
      - action: 'teams.roles:add'
        scope: 'permissions:type:delegate'
        state: 'absent'
      # Permissions to add
      - action: 'folders:read'
        scope: 'folder:*'
      - action: 'folders:write'
        scope: 'folder:*'

You can also change basic roles’ permissions using the API. Refer to the RBAC HTTP API for more details.

Reset basic roles to their default

This section describes how to reset the basic roles to their default.

You have two options to reset the basic roles permissions to their default.

Use the configuration option

Note: Available as of Grafana Enterprise 9.4.

Warning: If this option is left to true, permissions will be reset on every boot.

Use the reset_basic_roles option to reset basic roles permissions to their default on Grafana instance boot up.

1. Open you configuration file and update the rbac section as follow:

bash Copy

[rbac]
reset_basic_roles = true

Use the http endpoint

An alternative to the configuration option is to use the HTTP endpoint.

1. Open the YAML configuration file and locate the roles section.

2. Grant the action: "roles:write", scope: "permissions:type:escalate permission to Grafana Admin. Note that this permission has not been granted to any basic roles by default, because users could acquire more permissions than they previously had through the basic role permissions reset.

   yaml Copy

   apiVersion: 2
   roles:
     - name: 'basic:grafana_admin'
       global: true
       version: 3
       from:
         - name: 'basic:grafana_admin'
           global: true
       permissions:
         # Permission allowing to reset basic roles
         - action: 'roles:write'
           scope: 'permissions:type:escalate'

3. As a Grafana Admin, call the API endpoint to reset the basic roles to their default. Refer to the RBAC HTTP API for more details.

Delete a custom role using Grafana provisioning

Delete a custom role when you no longer need it. When you delete a custom role, the custom role is removed from users and teams to which it is assigned.

Before you begin:

• Identify the role or roles that you want to delete.
• Ensure that you have access to the YAML configuration file.

To delete a custom role:

1. Open the YAML configuration file and locate the roles section.

2. Refer to the following table to add attributes and values.

   Attribute	Description
   name	The name of the custom role you want to delete. You can specify a uid instead of a role name. The role name or the uid are required.
   orgId	Identifies the organization to which the role belongs.
   state	The state of the role set to absent to trigger its removal.
   force	When set to true, the roles are removed even if there are existing assignments.

3. Reload the provisioning configuration file.

   For more information about reloading the provisioning configuration at runtime, refer to Reload provisioning configurations.

The following example deletes a custom role:

yaml Copy

# config file version
apiVersion: 2

roles:
  - name: 'custom:reports:editor'
    orgId: 1
    state: 'absent'
    force: true

You can also delete a custom role using the API. Refer to the RBAC HTTP API for more details.
