The long-term goal of the REX-Ray project is to enable collaboration between organizations focused on creating enterprise-grade storage plugins for the Container Storage Interface (CSI). As a rapidly changing specification, CSI support within REX-Ray will be planned when CSI reaches version 1.0, currently projected for a late 2018 release. In the interim, there remains active engagement with the project to support the community.
REX-Ray provides a vendor agnostic storage orchestration engine. The primary
design goal is to provide persistent storage for
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
Documentation provided at RTD is based on the latest stable build. The
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/

The following command will install the REX-Ray client-server tool. If using
Ubuntu the necessary service manager is used
to bootstrap the process on startup
curl -sSL https://rexray.io/install | sh -
Runtime - CLI
REX-Ray can be run as an interactive CLI to perform volume management capabilities.
$ export REXRAY_SERVICE=ebs $ export EBS_ACCESSKEY=access_key $ export EBS_SECRETKEY=secret_key $ rexray volume ls ID Name Status Size vol-6ac6c7d6 attached 8
Runtime - Service (Docker)
Additionally, it can be run as a service to support
Mesos, and other
platforms that can communicate through
$ export REXRAY_SERVICE=ebs $ export EBS_ACCESSKEY=access_key $ export EBS_SECRETKEY=secret_key $ rexray service start Starting REX-Ray...SUCCESS! The REX-Ray daemon is now running at PID XX. To shutdown the daemon execute the following command: sudo /usr/bin/rexray stop $ docker run -ti --volume-driver=rexray -v test:/test busybox $ df -h /test
Runtime - Docker Plugin
Starting with Docker 1.13, Docker now supports a new plugin architecture in which plugins can be installed as containers.
$ docker plugin install rexray/ebs EBS_ACCESSKEY=access_key EBS_SECRETKEY=secret_key Plugin "rexray/ebs:latest" is requesting the following privileges: - network: [host] - mount: [/dev] - allow-all-devices: [true] - capabilities: [CAP_SYS_ADMIN] Do you grant the above permissions?
