Practical Docker for Developers: From First Container to Production

Tired of the "it works on my machine" excuse when deploying software? In modern development, packaging your application so it runs identically everywhere is a critical skill. This text-based course guides you from the fundamental principles of containerization to managing multi-container applications in production-like environments. You will learn to write efficient configurations, manage persistent data, and troubleshoot issues systematically. What you'll learn: - Understand core containerization concepts, terminology, and how Docker differs from traditional virtual machines. - Create lightweight, secure Docker images using multi-stage builds and best practices. - Configure multi-container environments with Docker Compose for local development and testing. - Manage persistent data using volumes and bind mounts to connect databases reliably. - Troubleshoot running containers, analyze logs, and resolve common networking issues. - Apply modern security practices, including rootless execution and secure environment variables. You will start with essential terminology and the inner workings of containers before advancing to practical configuration files and deployment workflows. The text-only format allows you to read, analyze code snippets, and practice commands at your own pace. This course is designed for beginner developers, QA engineers, and system administrators looking to adopt containerization. No prior Docker experience is required.
