About this Hands-on Lab

This lab provides practice scenarios to help prepare you for the Certified Kubernetes Application Developer (CKAD) exam. You will be presented with tasks to complete, as well as server(s) and/or an existing Kubernetes cluster to complete them in. You will need to use your knowledge of Kubernetes to successfully complete the provided tasks, much like you would on the real CKAD exam. Good luck!

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Dockerfile

Create a Dockerfile for an application.

There is a project directory at /home/cloud_user/buzz. All the necessary files are in this directory. Create a Dockerfile in /home/cloud_user/buzz.

Use the busybox:1.34.1 image as the baseline for your new image.

Configure the Dockerfile to place data1.txt from the buzz directory into the resulting container image at /etc/data/mainData.txt.

Add data2.txt to the container image at /etc/data/data2.txt, and add data3.txt to the container image at /etc/data/data3.txt.

Build and Save a Container Image

Build a container image using your Dockerfile located at /home/cloud_user/buzz/Dockerfile. Docker is already installed on the CLI server, and you can use Docker to build the image.

Give this image the tag buzz:1. You do not need to run a container using this image or push it to any remote repository.

Save a copy of the image to an archive file located at /home/cloud_user/buzz_1.tar.

Additional Resources

Use the provided environment to complete the tasks detailed in the learning objectives.

You can access a Docker installation and necessary lab components from the CLI server.

This lab includes a verification script to help you determine whether you have completed the objectives successfully. You can run the verification script with /home/cloud_user/verify.sh.
