DevOps Foundations: Containerization with Docker and Ansible

Modern software delivery relies heavily on speed, consistency, and automation. Understanding containerization and deployment automation is no longer optional for developers and system administrators looking to scale their applications. This course guides you from DevOps absolute beginner to confidently managing containerized environments, transitioning you from manual application setups to automated, predictable, and scalable deployments. What you'll learn: - Understand fundamental containerization concepts, terminology, and how Docker isolates applications. - Build custom container images using Dockerfiles with multi-stage builds for optimal size and security. - Configure container networking, volumes, and persistent storage for stateful applications. - Manage multi-container applications seamlessly using Docker Compose. - Apply basic system automation and configuration management using Ansible playbooks. - Implement container health checks and basic monitoring to ensure high availability in production. You will begin by exploring core virtualization and container concepts before diving into hands-on configuration files. The course moves step-by-step from single-container commands to multi-container orchestration and automated deployment strategies through written explanations and clear code snippets. This text-based course is designed for aspiring DevOps engineers, system administrators, and software developers with no prior container experience.
