Introduction

This is a sample repo that contains the source code for the nginx application that can be deployed as container or on OpenShift, the index page also displays an welcome message for IBM zCX on OpenShift.

1. Create your project namespace in the cluster.

How to make change (in both source code and OpenShift application deployment)

1. Modify the the source code in git repo, here we changed the header text in the index.html page.
   
2. Once the change has been commited, go back to OpenShift web console and click the Start Build button in the deployment typology page to rebuild the nginx contianer image, onces the new image is built, OpenShift will automatically deploy the new container.
   
3. Open the same url location under the Routes section for nginx application or refresh the nginx index page, you should see the header change.
