Docker Machine is a technology that enables the Docker Engine—the application virtualization piece of Docker—to be quickly deployed on any server. Docker Swarm provides Docker container clustering capabilities, and Docker Compose enables multiple containers to be pulled together to run a single logical application.
“These are the first versions that a broad set of users could get their hands on to download to use in their environments,” David Messina, vice president of enterprise marketing at Docker Inc., told eWEEK.
The Machine and Swarm releases are Beta milestones, while Compose is a 1.1 release. Compose is based on the Fig project that Docker Inc. gained through the acquisition of Orchard in October 2014, according to Messina.
