Docker

Docker is a revolutionary software platform that allows developers to build, test, and deploy applications quickly using containers. Containers package an application with all of its dependencies, ensuring that it runs reliably across different computing environments.

Originally starting as an internal project at dotCloud, a platform-as-a-service company, Docker was released as an open-source project in 2013. The company later rebranded itself as Docker, Inc. to focus entirely on the container technology. Today, it is headquartered in Palo Alto, California, and remains a privately held company that leads the industry in containerization standards and developer tools.
