Part 1
CKA from zero, part 1: building the lab and learning why pods come back
I start CKA prep with no Kubernetes experience: a pinned kind and Calico lab on WSL, four setup traps, and a first lesson on why deleted pods come back.
Series
Kubernetes: From Zero to Hero
Building and operating my own Kubernetes lab (v1.37): a multi-node cluster with Calico for network policies, metrics-server for autoscaling, and the Gateway API. Next comes a kubeadm setup on Ubuntu VMs to practise installs, version upgrades and etcd backup/restore. Everything is reproducible: pinned versions, idempotent bash scripts, all in git.
