Overview of this book

Kubernetes is a modern cloud native container orchestration tool and one of the most popular open source projects worldwide. In addition to the technology being powerful and highly flexible, Kubernetes engineers are in high demand across the industry. This book is a comprehensive guide to deploying, securing, and operating modern cloud native applications on Kubernetes. From the fundamentals to Kubernetes best practices, the book covers essential aspects of configuring applications. You’ll even explore real-world techniques for running clusters in production, tips for setting up observability for cluster resources, and valuable troubleshooting techniques. Finally, you’ll learn how to extend and customize Kubernetes, as well as gaining tips for deploying service meshes, serverless tooling, and more on your cluster. By the end of this Kubernetes book, you’ll be equipped with the tools you need to confidently run and extend modern applications on Kubernetes.

Chapter 3 – Running Application Containers on Kubernetes

  1. If you had development, staging, and production environments, you could make one namespace for each.
  2. The Node that the Pod is running in could be in a broken state where the control plane cannot reach it. Typically, when a Node gracefully exits the cluster, the Pod will simply be rescheduled instead of showing an Unknown status.
  3. To prevent memory-hungry Pods from taking over the entire Node and causing indeterminate behavior in other Pods on the Node.
  4. You should add more delay to the Startup probe if you have one. If not, you will need to add one, or add a delay to the Readiness probe.
