Configure kubectl access to your clusters: kubeconfig, contexts and default namespace
Read a kubeconfig and tell which cluster, identity and namespace kubectl will act on, switch context permanently or for a single command, change the default namespace, create, rename and delete a context, merge a kubeconfig you received without overwriting your own and protect these files: 600 permissions, never in Git.

Beyond the lessons
Assess, practise, pass the proof
Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.
