Packer for Infrastructure Automation: Build Immutable Cloud Images

In modern cloud engineering, manual server configuration is a major source of deployment failures and security vulnerabilities. This text-based course guides you through Packer, the industry standard for automating the creation of identical machine images for multiple cloud platforms simultaneously. You will transition from manually configuring virtual machines to defining infrastructure as code, allowing you to build, test, and deploy consistent, pre-configured images. By reading through clear conceptual explanations and analyzing structured configuration examples, you will learn how to integrate image building into modern deployment pipelines. What you'll learn: - Understand the core principles of immutable infrastructure and Packer terminology - Write clean and maintainable Packer templates using modern HCL syntax - Configure builders to generate machine images for AWS, Azure, and GCP - Apply provisioners to automate software installation and system configuration - Use post-processors to compress, upload, and manage your finished images - Integrate Packer templates into modern CI/CD automation workflows. The course begins with foundational concepts, key terminology, and the philosophy of immutable infrastructure before moving into template structure, variable management, and multi-provider configurations. You will progress from simple local builds to complex, multi-stage cloud image pipelines entirely through written guides and practical code walkthroughs. This course is designed for system administrators, DevOps beginners, and cloud engineers who want to automate image creation with no prior Packer experience required.
