Building and Running Containerized Applications

In modern software development, ensuring your application runs the same way on your laptop as it does in production can be a major challenge. Containerization solves this by packaging your code with all its dependencies into a single, portable unit. This text-based course guides you from the absolute basics of container technology to successfully building and running your own containerized applications. You will learn the core concepts, read through practical configuration examples, and understand how to optimize your deployment workflow. What you'll learn: - Understand containerization terminology, including the differences between virtual machines and containers - Write clean and secure Dockerfiles to package application code and dependencies - Implement multi-stage builds to minimize container image size and improve performance - Manage container storage and networking to persist data and enable communication between services - Use Docker Compose to define and run multi-container applications locally - Apply modern security best practices, such as running containers as non-root users You will start by exploring foundational container concepts and terminology before moving on to practical step-by-step guides for writing configuration files and launching services. The course concludes with advanced packaging strategies and security practices for production-ready containers. This course is designed for software developers, system administrators, and DevOps beginners who want to adopt modern container workflows. No prior container experience is required.
