Configuring RBAC with CasC for controllers

You can configure global Role-Based Access Control (RBAC) by adding the rbac.yaml file to the configuration bundle. Additionally, the authorizationStrategy attribute must be added to the jenkins.yaml file.

Prerequisites

The following software and plugins must be installed to use RBAC with CasC:

If using CloudBees CI 2.249.3.1 - 2.303.3.3: CloudBees CasC API (Deprecated) plugin, version 1.2 - 1.41
If using CloudBees CI 2.319.1.5 or later: CloudBees CasC Client plugin, version 1.44 or later
Configuration as Code plugin

Required setup

You can define groups and roles at the controller-level using the Configuration as Code rbac.yaml file.

Controller authorization strategy: To apply RBAC settings (rbac.yaml) to a controller using CasC, the controller’s authorization strategy must not be inherited from operations center. For more information, see Configuring the controller authorization strategy.
User management: Users need to be created in your CloudBees CI system either by an identity provider (like LDAP) or manually. The examples below assume the users exist.
Item management: To apply RBAC groups and/or roles to items, the CasC configuration bundle must include an items.yaml file with the defined items.

For more information, refer to Creating items with CasC for controllers.

Configuring the controller authorization strategy

To apply RBAC settings (rbac.yaml) to an individual controller using Configuration as Code, the controller’s authorization strategy must not be inherited from the operations center.

If groups and roles are defined in the operations center or if RBAC is only used with the items.yaml file, you do not need to opt out of inheriting the operations center’s authorization strategy.

To configure the controller authorization strategy:

Ensure you are signed in to the operations center as a user with the Administer permission.
From the operations center dashboard, in the left pane, select Manage Jenkins.
Select Configure Global Security.
Scroll down to Client controller security and select Allow client controllers to opt-out.
Select Save.

For more information on how to customize the authorization strategy for an individual controller, refer to Configuring SSO in the operations center.
From the operations center dashboard, select the down arrow to the right of your controller’s name, and then select Configure.

Figure 1. Controller dropdown menu
Scroll down to Security Setting Enforcement and select either Enforce Authentication only or Opt out of all security enforcement.

For more information on how to customize the authorization strategy for an individual controller, refer to Configuring options for individual controllers.

Exporting RBAC configurations

You can export Role-Based Access Control (RBAC) configurations from an existing controller. For more information, refer to Exporting a CasC configuration.

The exported file should be used as a starting point, as it may require modifications and adjustments to make it production-ready.

1	`version` (required) - must currently have the value 1, which defines the current metadata format for the plugin catalog.
2	Add the `manage-permission` plugin to enable the Overall/Manage permission.
3	Replace 1.0.1 with the most recent version.

Example items.yaml file

If a CloudBees CI GitHub Organization is used to configure a repository from a GitHub Enterprise server and you add the server to the Configure System screen, API endpoint is a required field. You must verify that the apiUri property is configured in the items.yaml file. If the GitHub server is not an enterprise server, you can optionally remove the apiUri property from the items.yaml file.
