I’m studying for the CKA exam and I’m worried about installing CNI. According to the training.linuxfoundation.org website, installing a Kubernetes cluster with Kubeadm is a core competency of the exam. The official Kubernetes documentation has detailed notes on how to perform all the steps with the exception of how to install the CNI. Since this is vendor dependent and the documentation is supposed to be vendor agnostic, this portion is missing.
This leaves me in a bind during the exam. How am I supposed to install the CNI? Am I supposed to just memorize the command to install one CNI plugins? Admittedly I can do it with a single command, but it typically has a long url that is difficult to remember.
