Demos for Red hat Academy Instructor Webinare May 2020

Webinar Training Webinar: Deploying Containerized Applications - September 29 2020

This demo is to showcase why understanding Linux is important before you can dive into containers, Kubernetes and Openshift.

In this demo a very simple web-application, based on one index.html is deployed in three different ways.

Demo 1 - traditional webapp deployment

In demo 1, the web application is deployed in the traditional way on a VM. To replay this demo, you need a test system with RHEL7/8 or CentOS 7/8.

Demo 2 - webapp in a container on a stand-alone runtime host

In demo 2, the same web application is containerized using podman.

An image is created and stored in local cache and then a container is started from this image.

To recreate this demo, you need a test system with RHEL8/CentOS8.

The container tools should be installed by default.

Demo 3 - webapp in Openshift

In demo 3, the webapp will be deployed in an all-in-one Openshift 4.4 cluster using CodeReadyContainer.
