What-is-DockerIn layman terms, Docker means a person employed in a port to load and unload ships.

Technically, it is a software platform that builds, test, and deploy applications quickly.

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.
