Introduction to Bottlerocket: Container-Optimized Linux OS

Running containers on traditional operating systems introduces unnecessary overhead, larger attack surfaces, and complex update cycles. This text-based course introduces Bottlerocket, a minimal, open-source Linux-based operating system designed specifically for hosting containers. You will learn how Bottlerocket improves security, reduces resource usage, and simplifies maintenance compared to general-purpose operating systems. Through structured explanations and configuration examples, you will understand how to launch, configure, and update Bottlerocket instances within modern container environments. What you'll learn: - Understand the core architecture and design principles of Bottlerocket - Configure Bottlerocket instances using declarative settings and user data - Deploy Bottlerocket nodes within Kubernetes and ECS clusters - Manage secure, transactional updates with automatic rollbacks - Apply modern container security practices, including read-only root filesystems - Troubleshoot and adminster nodes using the control container and admin container The course begins with foundational concepts of container-optimized operating systems before walking you through system configuration, cluster integration, and update management. It is designed for developers, systems administrators, and DevOps beginners who want to build secure and efficient container infrastructure without prior operating system customization experience.
