16장. Using declarative configuration

With declarative configuration, you can update configurations by storing them in files in repositories and apply them to the system. Declarative configuration is useful, for example, if you are using a GitOps workflow. You can currently use declarative configuration in Red Hat Advanced Cluster Security for Kubernetes (RHACS) for authentication and authorization resources such as authentication providers, roles, permission sets, and access scopes.

To use declarative configuration, you create YAML files that contain configuration information about authentication and authorization resources. These files, or configurations, are added to RHACS by using a mount point during Central installation. See the installation documentation in the "Additional resources" section for more information on configuring mount points when installing RHACS.

The configuration files used with declarative configuration are stored in config maps or secrets, depending on the type of resource. Store configurations for authentication providers in a secret for greater security. You can store other configurations in config maps.

A single config map or secret can contain more than one configuration of multiple resource types. This allows you to limit the number of volume mounts for the Central instance.
