Kubernetes the Hard Way, from Scratch!

on YouTube ↗36m

" summary

Builds a Kubernetes cluster from scratch on Alpine Linux VMs, creating eight nodes plus an external ETCD trio and a CEPH storage cluster, and deploys 83 pods for one website. Covers concrete operational issues and solutions: container startup times (~20 ms), hitting a 70-container ulimit, SSH entropy problems, rotating expired TLS certificates, replacing Docker with containerd/CRI, using MetalLB and kube-router (making kube-proxy optional), and performing live Kubernetes upgrades from v1.19 to v1.32.
