ocker is an open source software which is based on virtualization technology at OS-level to run software in isolated packages called containers. Docker is built on a large and active community that makes access to new features and a large range of images very easy.

A Docker image is a read-only (immutable or unchangeable) file that contains a set of instructions representing multiple layers and that is used to execute code in a Docker container.

You can see the Docker image as a snapshot of a ready to use application or environment and the Docker Container as a running version of that image.

Once the container is created, you can start it by using the docker start command or docker container start one.
