Developers who can build, design, configure, and troubleshoot applications in Kubernetes are in high demand. The O'Reilly Certified Kubernetes Application Developers (CKAD) study guide goes in-depth on the topics you need to pass the CKAD exam, including practical sample exercises. Learn core principles of services and networking, and gain a thorough understanding of state persistence and volumes.

To help prepare developers for the exam, Cockroach Labs is providing two free chapters from the study.

In this free two chapter excerpt, you will learn:

• The core concepts behind Pods and Services, central concepts in Kubernetes
• How to create and manage Pod-to-Pod communication through a Service
• How to create network policies and minimize attacks from outside vectors
• How to configure PersistentVolumes and PersistentVolumeClaims and how to navigate their relationship to each other
