kubectl Commands Essentials

Welcome to kubectl Commands Essentials! In this lesson, you'll learn how to use kubectl, the command-line tool that lets you talk to your Kubernetes cluster.

Think of kubectl as your remote control for managing applications, inspecting cluster resources, and debugging issues directly from your terminal.

Before kubectl can do anything, it needs to know which Kubernetes cluster to talk to. This is handled by a kubeconfig file (usually ~/.kube/config).

• It contains connection details like cluster IP, authentication info.
• kubectl automatically uses the default context in this file.
• You can switch contexts to manage multiple clusters.
