Docker: Containerize Everything

Docker is a platform for developing, shipping, and running applications in containers. Containers package an application with all its dependencies into a standardized unit, ensuring it runs consistently across any environment — from your laptop to production servers to the cloud.

Docker has revolutionized how software is built and deployed. Our books cover everything from Docker fundamentals to production deployment, multi-stage builds, and Docker Compose for multi-container applications.
