  1. Challenge

    Install the Container Runtime (Docker)

    Log in to all three servers. Get Docker installed and running. For the purposes of this lab, you can use Docker version 19.03.12.

  2. Challenge

    Install the Kubernetes Packages (`kubeadm`, `kubelet`, and `kubectl`)

    On all three nodes, install kubeadm, kubelet, and kubectl. Don't forget to disable Swap, as doing so is a requirement for kubelet to work properly.

  3. Challenge

    Initialize the Cluster

    Initialize the Kubernetes cluster on the control plane node. Be sure to:

    • Supply the provided kubeadm configuration file located at ~/kubeadm-config.yml.
    • Instruct kubeadm to ignore any preflight errors that may arise.

  4. Challenge

    Install the Calico Network Add-On

    Install the Calico network add-on in your cluster.

  5. Challenge

    Join the Worker Nodes to the Cluster

    Join the two worker node servers to the cluster. Use kubectl get nodes on the control plane node to verify all three nodes are successfully registered and in the Ready state.
