Deep Dive into Kubernetes Internals for Builders and Operators

" summary

Builds a one‑node cluster from binaries: etcd, kube-apiserver, controller-manager, scheduler are started, then a deployment (nginx, three replicas) creates a ReplicaSet and pods; kubelet, docker, kube-proxy, CNI (kubenet then kube-router) are used to run pods, create iptables rules for ClusterIP services, and later add a second node. Networking breaks (duplicate pod IPs, missing routes, iptables blocking) are fixed manually; security and TLS for service accounts remain unaddressed.
