Kubernetes the Hard Way: A Live Journey
Talkat Cloud Native University 2025 · on Tuesday, 2025-04-01· at 13:30· Level 0 | ICC Capital Hall | Room J·
summary
Live assembly of a single-node cluster on remote machines in Amsterdam over Wi‑Fi, starting etcd, the API Server, controller-manager, scheduler, kubelet and kube-proxy via systemd; containerd provides the CRI. A Deployment for nginx is created, controllers produce Pods, the scheduler assigns a node and the kubelet runs the container so the demo succeeds. Note: this is explicit manual setup for learning not recommended for production.
