About this Hands-on Lab

In this hands-on lab, you will be provided with two servers. They have been partially configured for use with Kubernetes and containerd.

The cluster has been initialized, so you need to add a Node to the cluster, create an `nginx` Pod, and run the Pod. Verify successful completion by confirming the output is visible from the Nginx Pod.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Log In to the Provided Server

Log in to the server as cloud_user with the provided password to ensure you can log in. When the file SERVER-READY is visible in the /home/cloud_user folder, then you can follow along with the objectives.

Add Your Worker Node to the Cluster

Add your worker Node knode1 to the cluster using the information provided in the cluster-info text file, and check if it is ready for use.

Create an Nginx Pod File

You will create a Pod file that runs the Nginx image. Use port 80 for its output, and call the file, nginx-pod.yml.

Create a Pod from the File You Created

Using kubectl, create the Pod with the nginx-pod.yml file.

Test the Pod Is Working

Test the Pod you created is working.

You should use the IP address associated with the Pod and check from the knode1 server.

Additional Resources

You have been told that it’s easy to create a Pod in Kubernetes, and you have been tasked with testing if this is correct.

Your manager has asked you to perform some tasks on a partially built Kubernetes cluster that uses containerd.

You are to add a Node to the cluster using the information provided.

Create a Pod file that uses YAML. It should be called nginx-pod.yml.

Run the Pod and test you can see the output from it.
