Docker Community Edition (CE) is a free and open source containerization platform. It is a rebranded version of the Docker open source solution that has been freely available since the launch of Docker in 2013.
CE can run on Windows and Mac, on Azure and AWS, as well as CentOS, Debian, Fedora, and Ubuntu. CE can be downloaded directly from the Docker Store.
Docker CE is free to use and download, official vendor support isn’t available. The overall experience of CE can be enhanced through a range of free and paid add-ons from Docker Cloud at your own discretion.
