REX-Ray provides a vendor agnostic storage orchestration engine. The primary
design goal is to provide persistent storage for Docker containers as well as
Mesos frameworks and tasks.
It is additionally available as a Go package, CLI tool, and Linux service which enables it to be used for additional use cases.
You will find complete documentation for REX-Ray at rexray.readthedocs.org, including
licensing and
support information.
Documentation provided at RTD is based on the latest stable build. The /.docs
directory in this repo will refer to the latest or specific commit.
REX-Ray is available as a standalone process today and in the future (0.4)
additionally as a distributed model of client-server. The client performs a
level abstraction of local host processes (request for volume attachment,
discovery, format, and mounting of devices) while the server provides the
necessary abstraction of the control plane for multiple storage platforms/
