Docker Questions

What is Docker?

Docker provides an integrated technology suite that enables development and IT operations teams to build, ship, and run distributed applications anywhere. Docker allows you to package an application with all of its dependencies into a standardized unit for software development. Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries, anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.
