Developing and Packaging Containerized Applications for the Cloud

Modern cloud development relies heavily on containers to ensure applications run consistently across different environments. If you want to transition from writing local code to shipping production-ready cloud applications, understanding containerization is an essential first step. This text-only course guides you through the foundational concepts of containers, teaching you how to package applications efficiently and securely. You will transition from a local developer to someone who can confidently structure container images and prepare them for deployment on modern cloud platforms. What you'll learn: Understand the fundamental differences between virtual machines and containers; Create efficient Dockerfiles using multi-stage builds to minimize image size; Apply container security best practices, including using non-root users and minimal base images; Package and configure application environments with environment variables and volumes; Manage container registries and prepare images for seamless cloud deployment. You will start by exploring core container terminology and architecture before moving on to practical written exercises where you write configuration files and optimize images. Finally, you will study how these containerized applications integrate into cloud environments and deployment pipelines. This course is designed for beginner developers, system administrators, and aspiring cloud engineers who have no prior experience with containers or Docker.
