What is Docker?

Docker allows you to build and run containers.

What are containers?

Containers provide isolation of resources to a program such as:

• Networking
• Storage
• CPUs

Images

An image is a virtual disk that you provide to docker in order to run a container.

You can get many images such as Ubuntu, Python, etc

Pulling from hub.docker.com

Creating/Running a container

A container must be created from an image.

Images on your local machine can be found with docker image ls

Images can be used by calling their name:label or by calling their ID directly
