What Is Kubernetes?
Kubernetes for someone who's never used it. What it does, why AI clusters live on it, and the basic vocabulary (pods, deployments, services, namespaces) translated into network-engineer terms.
K8s Networking 101
How Kubernetes networking actually works. One IP per pod, the flat L3 model, CNI plugins (Calico, Cilium, Flannel), services and kube-proxy, NetworkPolicy, and the multi-NIC gap that requires Multus for AI workloads.
Operators and Helm
What an Operator is, the Operators you'll meet on every AI cluster (GPU, Network, SR-IOV), how to install them via Helm, and how to debug Operator-managed components.
