Docker Essentials: Getting Started with Containers and CI/CD

Modern software development requires applications to run reliably across different environments. Docker solves the classic "it works on my machine" problem by packaging software into lightweight, portable containers. This text-only course guides you from containerization novice to confidently running and deploying Dockerized applications. You will learn the core concepts of container technology, write optimized Dockerfiles, and connect your containers to automated deployment pipelines. What you'll learn: Understand the foundational concepts of containerization and how it differs from virtualization; Build custom container images using Dockerfiles and efficient multi-stage builds; Manage persistent data with Docker volumes and configure container networking; Secure your containers using lightweight base images and security best practices; Integrate Docker into modern continuous integration and continuous deployment (CI/CD) workflows. The course begins with essential terminology and the architecture of Docker before moving on to practical configurations, multi-container setups, and deployment strategies. You will progress through structured text explanations and code snippets designed to build your skills step-by-step. This course is designed for absolute beginners, software developers, and system administrators with no prior container experience.
