Details

Oracle Cloud Native Environment includes a Command Line Interface (CLI) that can manage the life cycle of Kubernetes clusters using OSTree-based container images. Oracle Cloud Native Environment includes several provider types you can use to create a Kubernetes cluster, and this tutorial introduces how to use the ocne cluster command to deploy a Kubernetes cluster to Oracle Cloud Infrastructure using the oci provider.

Creating a cluster on Oracle Cloud Infrastructure requires you to provide details of an existing tenancy and have all the necessary privileges to create and destroy compute instances. The oci provider requires a compartment that is available to use. The Compartment can be specified by referencing its Oracle Cloud Identifier (OCID) or its path in the compartment hierarchy.

For more information about Oracle Cloud Native Environment 2, please refer to the current Release Documentation.
