Containers, images and Docker Compose
Image vs container?
An image is a packaged template; a container is an instance created from that image.
What is Docker Compose?
Compose describes a multi-container application in YAML, including services, networks, volumes and configuration.
What is a volume?
A volume provides persistent storage that can survive container replacement.
How do containers communicate?
Containers on the same Docker network can generally reach one another using service names and the container's listening port.
