REX-Ray provides a vendor agnostic storage orchestration engine. The primary
design goal is to provide persistent storage for Docker, Kubernetes, and Mesos.
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 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/
