Oracle Kubernetes (OKE): Deploying a Custom Node.js Web Application Integrated with Identity Cloud Service for Unique Single Sign On (SSO) User Experience

In this post we are deploying a custom Node.js web application in Oracle Kubernetes Engine (OKE).

What we want to show is how to configure the custom web application in order to have a unique Single Sing On experience.

First part

Follow this tutorial here explaining how to enable SSO to the web app running locally

Second part

Now we are making small changes to deploy on kubernetes
