At this point you should already have an OpenShift cluster that you can use to deploy applications.
It may be a cluster running on VMs provisioned by a cloud provider or even a small cluster on your notebook using OpenShift Local.
You can access the console and log in to the cluster with the oc command-line utility.
But how do you deploy an application that your team built to the cluster?
Most applications running on OpenShift clusters are web-based. Such applications are usually accessed by users via a web browser, or as backends by apps installed to user-owned devices.
For the sake of this chapter you can use an arranged deployment consisting of three different services to practice deploying application code to your OpenShift cluster.
A small OpenShift Local cluster should provide enough capacity to deploy this application.
However, to follow some parts of the chapter you will need a cluster that is accessible externally.
The application used in this chapter is the arcade gaming platform of a fictitious game publisher.
It consists of the following components:
Games, each running in its own service (for now there is only one game).
A highscore service where the scores of every game and player can be shown.
