Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications.

Why is Docker needed?

Docker is an open source containerization platform. It enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.

Do I need Docker?

Docker is great for businesses of all sizes. When you are working on a piece of code in a small team, it eliminates the “but it works on my machine” problem. Meanwhile, enterprises can use Docker to build Agile software delivery pipelines to ship new features faster and more securely.
