Kubernetes for the Virtualization Admin
summary
Compares virtualization to containers and shows how Kubernetes replaces VM workflows with an API‑driven control plane using kube-apiserver and etcd, node agents like kubelet, and container runtimes (Docker/containerd/crio). Explains pods, deployments, PVC→PV storage, configMaps/secrets, services/Ingress, and network policies; gives a 3‑node statefulset database example to show identity and persistent storage semantics; notes clusters can run on VMs or bare metal and cites Kasten by Veeam for migration.
