If you're a developer, you most likely have heard of or worked in the world of containers and Docker. If not, you should.

Docker is a container platform making it easy to deploy and run applications with all the needed components including libraries and dependencies. Docker is like virtual machines without requiring whole virtual operating systems allowing for a significant performance boost and application size reduction. And it is open source.

The core of Docker are containers, a lightweight, stand-alone, executable package of software and everything you need to run it: code, runtime, libraries, tools, and settings. This allows for separate environments such as development and staging.

For WordPress developers, Docker allows you to quickly spin up a development environment for theme design, custom coding, and testing while maintaining a staging environment independent of the development environment for client review before production.
