Deploy 1 thousand pods in my JUST laptop (w/ kwok)
summary
Demonstrates deploying 1000 pods on 1GB VM by simulating nodes with KWOK (Kubernetes WithOut Kubelet) and a custom Helm chart that generates thousands of fake nodes from YAML and downloaded KWOK binaries. Shows scheduler behavior, taints/tolerations and affinity tests (pods prefer labeled H100 nodes), but cannot expose services or test real network traffic. Reports ~1,000 pods succeeds while 10,000 freezes the API server, and notes lower resource use helps cost and environmental sustainability.
