B. Reasons to use K9S when working with Kubernetes

  1. Efficiency – K9s provides a fast, terminal-based UI for navigating and managing Kubernetes resources without needing long kubectl commands.
  2. Live Monitoring – It offers real-time updates on pods, logs, and events, making troubleshooting easier.
  3. Automation & Shortcuts – Built-in hotkeys and commands speed up common tasks like scaling, deleting, or editing resources.
