** Docker Containers 101: Understanding Images and Containers

Docker provides two essential concepts for building, running, and managing applications: images and containers. An image is a read-only template with instructions for creating a Docker container, while a container is a runnable instance of an image.

To create an image, you can either take one from the Docker Hub or build your own using a Dockerfile. This file defines the steps needed to create the image and run it, resulting in lightweight and fast containers compared to other virtualization technologies.

Containers are created by running an image and can be controlled through the Docker API or CLI. You can connect containers to networks, attach storage, or even create new images based on their current state.
