Nodes are configured to poll the container registry to pull and stage the Oracle Container Host for Kubernetes (OCK) image for the target Kubernetes version. After the image is staged, use the ocne cluster update command to install the image and reboot the nodes.

ocne cluster stage 
[{-c|--config} path] 
[{-r|--os-registry} registry]
[{-t|--transport} transport]
{-v|--version} version

Where:

{-c|--config} path

The path to a configuration file that contains the definition of the cluster. If this value isn't provided, a small (ephemeral) cluster might be created, using the default hypervisor, for the system where the command is run.

{-r|--os-registry} registry

The name of the container registry to use during the upgrade. The default is container-registry.oracle.com/olcne.

{-t|--transport} transport

The transport type to use during the upgrade. The default is ostree-unverified-registry.

For a list of the available transports, see the upstream OSTree documentation.

{-v|--version} version

The target Kubernetes version. This must be the next available minor Kubernetes version.

ocne cluster stage --version 1.31
