Containerizing Go Applications with Docker

Go is known for its speed and efficiency, but managing dependencies and ensuring consistent environments across development and production can still be a challenge. Containerization solves these issues by packaging your application with everything it needs to run. This text-based course guides you through the foundational concepts of containerization and how to apply them specifically to Go applications. You will transition from writing local Go code to deploying fully containerized, production-ready applications. What you will learn: Understand the core concepts of virtualization, containerization, and the Docker architecture; Create optimized Dockerfiles specifically tailored for compiling and running Go binaries; Manage Go modules and external dependencies efficiently within a container build cache; Apply multi-stage builds to dramatically reduce your final Docker image size; Configure networking, expose application ports, and manage environment variables; Implement modern container best practices, including running processes as non-root users for security. You will start with the fundamental terminology of containers, images, and registries, before moving step-by-step through writing build instructions, optimizing compile times, and securing your runtime environment. This course is designed for backend developers, systems engineers, and beginners who want a clear, structured introduction to containerizing Go applications with no prior Docker experience required.
