Describes administration of Kubernetes clusters using the CLI.

This chapter contains information on using the CLI to administer Kubernetes clusters.

Cluster Updates

The ocne node update command is used to update the Oracle Container Host for Kubernetes (OCK) image on nodes in the cluster. Updating the OCK image is used for patch updates, and for minor Kubernetes updates.

Cluster Backups

Backups of a cluster can be done with the ocne cluster backup command.

Cluster Analysis

The ocne cluster dump and ocne cluster analyze commands are used to create and analyze a dump of cluster and node data from a Kubernetes cluster. Analyzing a cluster is useful for debugging and getting detailed information about a cluster.

OS Console

The ocne cluster console command is used to connect to the OS console of a node in a cluster. The console provides a method to connect to the host in a chrooted environment to perform debugging or inspection of the host's OS.
