An overview of Docker images.

What are Docker images?

It’s useful to think of a Docker image as an object that contains an OS filesystem, an application, and all application dependencies. If you work in operations, it’s like a virtual machine template. A virtual machine template is essentially a stopped virtual machine. In the Docker world, an image is effectively a stopped container. If you’re a developer, you can think of an image as a class.

At the end of this lesson, a terminal is provided where you can run the commands.

Run the docker image ls command on your Docker host.
