Developing Kubernetes Applications with Go

Kubernetes has become the operating system of the cloud, but managing complex deployments often requires extending its core capabilities. This text-only course teaches you how to leverage Go, the native language of Kubernetes, to build custom controllers, automate resource management, and implement continuous reconciliation. You will transition from a basic understanding of container orchestration to designing your own cloud-native automation tools. By reading through clear explanations and structured code breakdowns, you will master the internal mechanics of the Kubernetes API and learn how to programmatically control your infrastructure. What you'll learn: - Understand the core architecture of the Kubernetes API and how Go interacts with it - Build custom controllers and operators using modern client-go libraries and controller-runtime - Implement continuous reconciliation loops to maintain desired cluster states - Define and manage Custom Resource Definitions (CRDs) programmatically - Apply modern Go practices, including structured logging, context propagation, and unit testing with mock clients - Secure your custom integrations using standard Kubernetes authentication and RBAC configurations The course begins with foundational concepts, establishing a solid understanding of Kubernetes API machinery, resource definitions, and Go client libraries. From there, you will progress step-by-step through designing, writing, and deploying your own custom controllers. This course is designed for software developers, DevOps engineers, and system administrators who want to move beyond YAML files and start programming their infrastructure. No prior experience with Kubernetes API development is required, though a basic familiarity with Go syntax and general container concepts is recommended.
