1.4. Glossary of terms

The processes that are used to manage application resources on your managed clusters. A multicluster application uses a Kubernetes specification, but with additional automation of the deployment and lifecycle management of resources to individual clusters.

A custom resource definition that points to repositories where Kubernetes resources are stored, such as a Git repository, Helm chart repository, object store, or hub cluster namespace. Channels support multiple subscriptions from multiple targets.

Defines the process of creating, importing, and managing clusters across public and private clouds.

The graphical user interface for Red Hat Advanced Cluster Management.

A resource that retrieves the output of a build, packages the output with configuration properties, and installs the package in a predefined location so that it can be tested or run.

The Red Hat Advanced Cluster Management processes used to manage security and compliance.

The central controller that runs in a Red Hat Advanced Cluster Management for Kubernetes cluster. From the hub cluster, you can access the console and components found on that console, as well as APIs.

Created and imported clusters are managed by the klusterlet agent and its add-ons, which initiates a connection to the Red Hat Advanced Cluster Management for Kubernetes hub cluster.

The agent that contains two controllers on the managed cluster that initiates a connection to the Red Hat Advanced Cluster Management for Kubernetes hub cluster.

Specialized controller on the Klusterlet that provides additional management capability.

A policy that defines where the application components should be deployed and how many replicas there should be.

A rule that defines the target clusters where subscriptions are delivered. For instance, verify the cluster name, resource annotations, or resource label(s).

Identify Kubernetes resources within channels (resource repositories). The subscription places the Kubernetes resources in the same namespace, where it is created on the subscribed target clusters.
