### Start a container
A container is an instance created from an image, that can be run and that keeps running until its main process exits. Or until the user stops the container.
The simplest way to start a container from image is ``docker run``. It also pulls the image for you if it is not locally available. For more advanced use, refer to ``docker create``.
