About this Hands-on Lab

Kubernetes includes a variety of features that can simplify the process of administering robust applications. In this lab, you will have the opportunity to practice your application administration skills in Kubernetes by building a dev environment, retrieving logs, and running an administrative job. This will help you build familiarity with the ways in which you can administer Kubernetes applications.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Development Environment in the Cluster

Create a new Namespace called dev.

Deploy the app, including the backing service, to the dev Namespace.

You can find deployment descriptors for the frontend and backend in /home/cloud_user. Note that you may have to change the external ports used by NodePort Services for the dev Services to avoid port conflicts on the host. You can use ports 30082 and 30083 for this purpose.

Retrieve Container Logs

Retrieve the container logs for the frontend container in the production Namespace and save them to a file at /home/cloud_user/production-frontend.log.

Run the Admin Process

The frontend container image contains some code for an admin cleanup process. Use a Job called cleanup-job to run node cleanup.js using the linuxacademycontent/pirate-day:0.0.4 image. Run the Job in the production Namespace.

Additional Resources

Welcome to PirateCorp! A company that exists to promote pirate-related history and lore!

We're developing our new website, Is It International Talk Like a Pirate Day?. This site will inform the public of whether or not it is currently International Talk Like a Pirate Day.

Today, we need to perform some administrative tasks.

You will need to create a dev environment that closely matches the existing production environment. You can do this in the existing cluster but using a different Namespace. You will also need to obtain some container logs and execute an administrative job for the application.
