About

The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs.

You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.23 client can communicate with v1.22, v1.23, and v1.24 control planes. Using the latest compatible version of kubectl helps avoid unforeseen issues.
