A (Docker Container) is a virtualized runtime environment used in application development. It is used to create, run and deploy applications that are isolated from the underlying hardware. A Docker container can use one machine, share its kernel and virtualize the OS to run more isolated processes.
Think of a container as a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
