Packaging and Shipping Kubernetes Operators with Helm and Manifests

Deploying complex, stateful applications on Kubernetes requires a robust packaging and delivery strategy. Understanding how to ship Kubernetes operators ensures your custom controllers and custom resource definitions are easily installable, maintainable, and reproducible across multiple environments. This text-based course guides you through the foundational concepts of operator packaging, from basic raw manifests to structured Helm charts. You will start by learning core operator terminology and understanding how custom resource definitions (CRDs) interact with the control plane. From there, you will transition into hands-on packaging strategies, exploring the benefits of raw manifests for simple setups and Helm for scalable, templated deployments. You will also learn how to manage application lifecycles, configuration values, and clean upgrade paths. What you'll learn: - Understand the core architecture of Kubernetes operators, controllers, and custom resource definitions - Package operators using raw YAML manifests for simple, direct cluster deployments - Build dynamic Helm charts to template operator configurations and manage dependencies - Configure secure role-based access control policies tailored for operator permissions - Implement clean upgrade and rollback strategies for operators and their custom resources - Apply modern declarative GitOps principles to manage operator lifecycles automatedly This course is structured to take you step-by-step from raw YAML configurations to production-ready Helm packages, focusing on clear explanations and real-world configuration examples. It is designed specifically for beginners to Kubernetes packaging, software engineers, and DevOps professionals who want to automate application management. No prior experience with operators or Helm is required, though a basic familiarity with Kubernetes concepts is helpful.
