Docker challenges virtualization market with containers

The Docker release focuses on improving the stability and overall quality of the application container

Originally designed to run on Linux, the software is being reconfigured as a plug-in architecture that could allow it to work on other platforms as well, such as Microsoft Windows, through the use of a hypervisor.

The software also supports, for the first time, the experimental BTRFS (B-Tree File System).

Going forward, Docker will be updated once a month, with the next release, 0.9, issued in early March. New editions may or may not have major new features.

"If a feature is merged before the release date, it gets released. Otherwise, the next merge window is only a month away," Hykes wrote.

Version numbering will follow the lead of Linux, in which a change in the first digit represents a major upgrade. An advance in the second digit after the period designates a routine update and the third digit will be for emergency bug fixes and other issues.

Docker is planning for a full production-ready "version 1" release of the software in April.

The company is also investigating various strategies to commercialize the open source technology, which is under an Apache License. Docker plans to develop the services for indexing and signing images as well as for creating private registries for Docker images. It will also offer commercial support for Docker and is considering releasing an enterprise edition of the software as well.
