In the final part of this series, we will set up CI/CD hooks for the Kr8sswordz Puzzle app.

Set Up CI/CD for a Distributed Crossword Puzzle App on Kubernetes (Part 4)

Part 3 had us running our Kr8sswordz Puzzle app, spinning up multiple instances for a load test, and watching Kubernetes gracefully balance numerous requests across the cluster. Though we set up Jenkins for use with our Hello-Kenzan app in Part 2, we have yet to set up CI/CD hooks for the...
