It is a set of platform-as-a-service (PaaS) products that use OS-level virtualization to deliver software in packages called containers.
Docker packages an application and dependencies in a virtual container and ships it out as one package.
This enables flexibility and portability; enabling to run the application on on-premises, public cloud, or private cloud.
