Cluster Administrator Tasks

Perform a set of tasks to create OKE clusters on Compute Cloud@Customer.

Prerequisites

Perform the following tasks on your local system that you use to administer OKE:

  1. Configure the OCI CLI so you can run CLI commands. See Command Line Interface (CLI).

    If you already have the OCI CLI installed, use oci -v to check the version. The minimum required version for using OKE is 3.15.1.

    If you work in more than one tenancy, create a profile for each tenancy as described in Creating a Profile in the Oracle Cloud Infrastructure CLI Configuration File.

  2. Install the Kubernetes client command line tool, kubectl. See Install kubectl.

    If you already have kubectl installed, ensure the version is within one minor version of the Kubernetes version that you're using. See Supported Versions of Kubernetes.
