Chapter 9: Deployment and Day 2 Operations
So far, we've seen many code snippets and screenshots of our example application, the IBM Stock Trader. Now, let's learn how to deploy it to your own OpenShift Container Platform cluster or any Kubernetes platform of your choice. As important as getting it running is, it is also very important to learn how to maintain it and tune it to meet your needs.
Unlike many Hello World samples that you might see on the internet, that either have no operator at all (just having you manually apply .yaml
