Red Hat Summit5.4. User access to extension resources
After a cluster extension has been installed and is being managed by Operator Lifecycle Manager (OLM) v1, the extension can often provide CustomResourceDefinition objects (CRDs) that expose new API resources on the cluster. Cluster administrators typically have full management access to these resources by default, whereas non-cluster administrator users, or regular users, might lack sufficient permissions.
OLM v1 does not automatically configure or manage role-based access control (RBAC) for regular users to interact with the APIs provided by installed extensions. Cluster administrators must define the required RBAC policy to create, view, or edit these custom resources (CRs) for such users.
The RBAC permissions described for user access to extension resources are different from the permissions that must be added to a service account to enable OLM v1-based initial installation of a cluster extension itself. For more on RBAC requirements while installing an extension, see "Cluster extension permissions" in "Managing extensions".
5.4.1. Common default cluster roles for users
An installed cluster extension might include default cluster roles to determine role-based access control (RBAC) for regular users to API resources provided by the extension. A common set of cluster roles can resemble the following policies:
viewcluster role- Grants read-only access to all custom resource (CR) objects of specified API resources across the cluster. Intended for regular users who require visibility into the resources without any permissions to modify them. Ideal for monitoring purposes and limited access viewing.
editcluster role- Allows users to modify all CR objects within the cluster. Enables users to create, update, and delete resources, making it suitable for team members who must manage resources but should not control RBAC or manage permissions for others.
admincluster role-
Provides full permissions, including
create,update, anddeleteverbs, over all custom resource objects for the specified API resources across the cluster.
