Installing and Testing the Components of a Kubernetes Cluster

In this lab, you will build a cluster from scratch, as well as test the components of the cluster (including the deployments, pods, port forwarding, and services) and execute a command from within a pod. In order to build the Kubernetes cluster, we need to install the container runtime, as well as kubeadm, kubectl, and kubelet. We will then initialize the cluster, add our CNI, and add the nodes to the cluster.

Challenge

Install a Three Node Cluster
- Get the gpg keys for containerd and Kubernetes and add it to your repository
- Install containerd, kubelet, kubeadm, and kubectl
- Initialize the cluster with the pod CIDR address 10.244.0.0/16
- Setup the local kubeconfig
- Apply the Calico CNI plugin
- Join the worker nodes to the cluster
Challenge

Create a Deployment
- On the master node, create a deployment named ngnix, using the nginx image
Challenge

Expose Port 80 on the Pod
- On the master node, forward the container port 80 to 8081
- Open a new shell to the Kubernetes master and curl port 8081 on localhost
Challenge

Get the NGINX version running on the pod
- In the original master node terminal, run the nginx -v command from inside the pod
Challenge

Create a service, and verify connectivity on the node port
- In the original master node terminal, run the commands to expose the deployment and create a NodePort service
- Get the name of the node that the pod resides on
- Run the curl command to that node, using the port from the service, and verify connectivity
