About Docker

First appeared in 2013, 7 years ago

Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and therefore use fewer resources than virtual machines. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. It was first started in 2013 and is developed by Docker, Inc.

Docker Inc. was founded by Solomon Hykes and Sebastien Pahl during the Y Combinator Summer 2010 startup incubator group and launched in 2011.[10] Hykes started the Docker project in France as an internal project within dotCloud, a platform-as-a-service company.Docker debuted to the public in Santa Clara at PyCon in 2013.[12] It was released as open-source in March 2013.[13] At the time, it used LXC as its default execution environment. One year later, with the release of version 0.9, Docker replaced LXC with its own component, which was written in the Go programming language. In 2017, Docker created the Moby project for open research and development.
