Configuring RBAC with CasC for the operations center

7 minute readScalabilityAutomation

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.

If the operations center items.yaml file is used to create controller items, the controller RBAC configuration is defined in the operations center items.yaml file.

Prerequisites

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

Required setup

  • User management: You must create users in your CloudBees CI system, either using an identity provider (like LDAP) or manually creating them. The examples below assume the users exist.

  • Item management: You must include an items.yaml file in the controller CasC bundle to apply RBAC groups and/or roles to items.

For more information, refer to Creating items with CasC for the operations center.

Exporting RBAC configurations

You can export role-based access control (RBAC) configurations from an existing operations center instance. 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.

Example CasC configuration bundle with RBAC

Example bundle.yaml file

id: "bundle-1" version: "1" apiVersion: "2" description: "My CloudBees Configuration as Code (CasC) bundle" jcasc: - "jenkins.yaml" jcascMergeStrategy: "errorOnConflict" plugins: - "plugins.yaml" items: - "items.yaml" rbac: - "rbac.yaml" variables: - "variables.yaml"

Example jenkins.yaml file

1 Required to use CloudBees RBAC configured using CasC.
2 Optional if using the items.yaml file to create a controller item. When visibility is set to true, all CasC bundles that do not have an availability pattern defined can be used by any controller. This option provides more flexibility, but is less secure.
3 When provisionControllerOnCreation is set to true, all managed controller items are provisioned automatically after they are created using CasC.
4 When fireAndForget is set to true, the automatic provisioning process starts immediately, and does not wait for the controller to be connected.
5 The amount of time, in seconds, to wait before starting the automatic provisioning process.
6 The amount of time, in seconds, to complete the automatic provisioning process. If fireAndForget is set to false, this timeout may prevent queued provisioning requests from being blocked.
7 The provisioning duration, in seconds. After the initial delay, controllers are provisioned at random in batches of 20 controllers, for this time period. Increase this value to increase the amount of time between controller provisioning requests. If provisioning more than 20 controllers, the provisioning process will exceed the specified duration.
8 Required to create client controller items. The url is the operations center URL.
9 Required if using a local folder on the operations center server or an SCM tool as the Configuration as Code bundle location.

Example plugins.yaml file

plugins: # In CAP - id: "cloudbees-casc-client" - id: "cloudbees-casc-items-api" - id: "cloudbees-casc-items-commons" - id: "cloudbees-casc-items-server" - id: "configuration-as-code" - id: "operations-center-rbac"

Example items.yaml file

  • If creating a new controller item, refer to Creating a new controller item using CasC for the operations center.

  • By default, shared agent and shared cloud agent items are configured to be taken online. To configure the shared agent or shared cloud agent item to be taken offline, add the takeOnline property to the items.yaml and set it to false. For example: takeOnline: false.

1 Settings for a managed controller with CloudBees High Availability (HA), with 3 replicas, autoscaling enabled allowing up to 5 replicas, and a CPU threshold of 80% to trigger upscaling. maxReplicas and targetCPUUtilizationPercentage are not required if autoscaling is disabled. Then maxReplicas is set to 0 by default.
2 Some settings, such as controller memory, require the controller to be reprovisioned for the setting to take effect. If the managed controller is running in High Availability (HA) mode, these changes trigger a rolling restart without reprovisioning.
