To protect a Kubernetes cluster with Commvault, you must configure a few entities in Commvault.
A Kubernetes service account. Commvault uses the service account to authenticate and access applications for running backups and other operations.
An access node. Access nodes are virtual machines, cloud instances, or physical servers that run backups and other operations. For Kubernetes, access nodes communicate with the Kubernetes API server to discover, protect, and recover applications.
Application groups. An application group is a set of data that you want to protect. For Kubernetes, the data is the Kubernetes applications, namespaces, namespaced objects, non-namespaced objects, and persistent volume data that you want to protect.
