Core Commands for Kubernetes



The Certified Kubernetes Application Developer Exam is a challenging, hands-on exam that requires you to configure and deploy applications and services in a real Kubernetes cluster. In this tutorial, I show how to run some basic kubectl commands that will get you started preparing for the CKAD.

In this video, I will show how to do the following in a Kubernetes cluster:

  • View and switch contexts
  • Setup your preferred text editor
    • vim is the default, but can be set to nano
  • View pods in all namespaces
  • View namespaces
  • Create a namespace called practice
  • Create a pod from yaml generated by the --dry-run flag
  • Delete the pod
  • Create the pod in the practice namespace
  • Exec into the pod
