CN230: Kubernetes Native Application Development

Learn how to build container-native applications and continuous integration chains powered by Kubernetes

Description

In this Cloud Native course, developers will learn how to build containerized applications targeted for enterprise-grade production environments. You’ll explore patterns in containerized application architecture, techniques for eliminating friction in the development process, how to test and debug containerized applications, and how to instrument applications with healthchecks, monitoring tools, and common container logging patterns. After mastering these techniques, we’ll turn our attention to devops and building container-native continuous integration pipelines powered by Jenkins and Kubernetes.
