 # Bootstrapping the Kubernetes Worker Nodes
 
-In this lab you will bootstrap three Kubernetes worker nodes. The following components will be installed on each node: [runc](https://github.com/opencontainers/runc), [gVisor](https://github.com/google/gvisor), [container networking plugins](https://github.com/containernetworking/cni), [containerd](https://github.com/containerd/containerd), [kubelet](https://kubernetes.io/docs/admin/kubelet), and [kube-proxy](https://kubernetes.io/docs/concepts/cluster-administration/proxies).
