Cloud-Native Microservices With Kubernetes - 2nd Edition

Key Takeaways

By focusing on the health check pattern and its implementation in Kubernetes, we have covered some best practices and important concepts. Let's remember the most important takeaways from this chapter:

• Health checks are vital for tracking the state of microservices and confirming they can respond to requests correctly.
• Kubernetes offers three probe types—Liveness, Readiness, and Startup—each with a distinct role in managing container health.
• Multiple probing methods (HTTP, Exec, TCP) give flexibility to adapt checks to the application’s design.
