Managing Kubernetes Applications with Helm Charts

Managing complex Kubernetes applications manually often leads to configuration errors, deployment inconsistencies, and scaling challenges. This text-only course provides a clear, step-by-step path to mastering Helm, the package manager that simplifies how you define, install, and upgrade even the most complex Kubernetes applications. You will transition from writing repetitive YAML manifests to creating reusable, parameterized templates that streamline your deployment workflows. Starting with foundational concepts, you will learn the core architecture of Helm, including charts, templates, and releases. You will understand how to manage application lifecycles, configure values files for different environments, and use modern container registries to store and share your charts securely. The curriculum also covers modern best practices, including chart versioning, dependency management, and basic integration with declarative GitOps workflows.
