Prerequisites for deploying applications to a Red Hat OpenShift Service on AWS

Time estimation: 45 mins.

To effectively run a deployment, this learning path will use a predetermined source code and container images. These are for the purposes of testing and learning the steps of deployment.

For this path, we will be using OSToy. OSToy is a simple Node.js application that we will deploy to Red Hat OpenShift Service on AWS. It is used to help us explore the functionality of Kubernetes.
