GitOps with Flux on Kubernetes for Beginners

Kubernetes offers incredible power for container orchestration, but managing deployments manually can quickly lead to configuration drift and operational chaos. This text-only course introduces you to Flux, the open-source tool that automates application deployment by syncing your cluster state directly with your Git repositories. You will start with the core concepts of GitOps, learn how to install and configure Flux, and establish a secure, automated continuous delivery workflow. By reading through clear explanations and structured configuration examples, you will transition from manual kubectl commands to a declarative, version-controlled infrastructure. You will learn to manage application updates, handle secrets securely, and keep your production environments predictable and reliable. What you'll learn: - Understand the core principles of GitOps and why declarative configuration is essential for modern cloud-native systems - Configure Flux to connect your Kubernetes clusters securely with Git repositories - Deploy and update applications automatically by committing changes to your repository - Manage environment-specific configurations using Kustomize and Helm with Flux - Monitor cluster synchronization and troubleshoot deployment drift using status commands - Apply modern security best practices for secret management within GitOps workflows The course begins with foundational definitions of GitOps and Kubernetes controllers, then guides you step-by-step through setting up your first Git-backed deployment pipeline. It concludes with essential practices for production maintenance and monitoring. This course is designed for software developers, system administrators, and DevOps beginners who want to build a modern, automated deployment pipeline. No prior experience with Flux or GitOps is required, though a basic familiarity with Kubernetes concepts and Git commands is recommended.
