Docker Mastery Course

Docker packages your app and everything it needs into a container that runs the same way on every machine. Start with your first container, learn images, Dockerfiles, volumes and networks, run multi-container apps with Docker Compose, push images to a registry, then build small, secure images and deploy them to a real server.
