Run commands at Kubernetes *nodes* via `privileged` DaemonSet + `nsenter` hack, very useful for setups requiring base packages pre-installed at nodes. Please take a moment to understand what it does, and *don't* use it for *production*. Grab the logs with: kubectl logs -n kube-system -l k8s-app=node-custom-setup -c init-node
