Fundamentals of Kubernetes - A Step-by-Step Development and Interview Guide (1st ed.)

Explore the world of Kubernetes and review the concepts needed to develop, deploy, and manage applications on this container platform. This step-by-step development guide is designed for those application development and support team applicants preparing for a Kubernetes interview. Concepts in the book are presented in Q&A format, framing questions exactly the way they are asked in an interview.  You’ll start by understanding how application development and deployment have evolved over the decades leading to containerization. You’ll then dive into the Kubernetes architecture and how all its components work together to form a cluster, what the important objects are, and how to exploit them to their full potential. You’ll also review Kubernetes deployment strategies and concepts related to rollout and rollback.  Moving on, you’ll look at two very important aspects of any computing ecosystem: networking and storage, see how to access control mechanisms in Kubernetes, and manage a Kubernetes cluster with the help of health checks, probes, and resource limits. Finally, the book addresses fundamental concepts related to Docker and discusses some Kubernetes and Docker best practices, such as the kubectl command line tool, and managing a Kubernetes cluster with the help of health checks, probes, and resource limits.
