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 thebuzz
directory into the resulting container image at/etc/data/mainData.txt
.Add
data2.txt
to the container image at/etc/data/data2.txt
, and adddata3.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
