Problem scenario
Both kubeadm and kubectl are tools and commands for Kubernetes. What are the differences between them?
Answer
kubeadm is for creating new Kubernetes clusters (as paraphrased from this Kubernetes.io page). The command can be used to create both master nodes as well as worker nodes (taken from pg 575 Kubernetes in Action).
kubectl is for running operations on one or more existing Kubernetes clusters (as paraphrased from this Kubernetes.io page).
