LEARN KUBERNETES USING THE DEVELOPER SANDBOX FOR RED HAT OPENSHIFT
Learning path | 5 resources | 1 hr | Published on March 1, 2024
The Developer Sandbox for Red Hat OpenShift is a great platform for learning and
experimenting with Red Hat OpenShift. Because OpenShift is built on Kubernetes,
the Sandbox is also a great platform for learning and experimenting with
Kubernetes.
This activity, written by Don Schenck, takes you through the creation of an
application using plain Kubernetes instead of OpenShift.

The Developer Sandbox for Red Hat OpenShift (Developer Sandbox) is a great
platform for learning and experimenting with Red Hat OpenShift. Because
OpenShift is built on Kubernetes, the sandbox is also a great platform for
learning and experimenting with Kubernetes. You can access and treat your
sandbox instance like you would any Kubernetes instance. That is to say, you can
ignore the fact that it’s OpenShift and simply use it as plain Kubernetes.
PREREQUISITES
You will need the following in order to complete this activity:
* A Developer Sandbox for Red Hat OpenShift account
* The Kubernetes command-line interface (CLI), kubectl, installed on your local
PC
* Git installed on your local PC
WHAT YOU WILL DO
In this learning path, you will:
* Access the Developer Sandbox and prepare a local Kubernetes configuration
* Clone source code repositories
* Create a back-end program called quotes and a React front-end program called
quotesweb
* Create a Persistent Volume Claim (PVC) and a Secret to be used with the
database
* Create a database and populate its table quotes
* Update the back-end program quotes and observe the results in quotesweb
* Destroy apod and observe Kubernetes' self-healing capability
WHAT YOU WILL LEARN
By the time you finish this learning path, you will know how to:
* Create a back-end application and a front-end application, then connect the
two
* Create a database application running in Kubernetes and populate it from your
command line
* Scale an application with one command
* Update an application on-the-fly
HOW LONG WILL THIS ACTIVITY TAKE?
* 60-90 minutes
PROGRAMMING LANGUAGES
* The back-end service is written in Python 3.8.
* The web interface is written in React.
* The database is a MariaDB instance.
Info alert: You do not need knowledge of these languages in order to complete
this activity.

PERSONAL NOTE FROM THE AUTHOR
Relax and be prepared to spend some quality time with this tutorial. We cover a
lot of ground, and I've attempted to mimic a real-life situation in order to
bring the most value to your time.
If you're new to Kubernetes, you'll go from zero to deploying applications in
this guide. You'll be rolling out a back-end application, a database, and a
front-end application. You'll also be scaling an application and updating
another application. Also, when commands are referenced inline, they are shown
in a different typeface, e.g., kubectl config view.
This is hands-on with skills that are 100 percent applicable to a production
environment.
