README

docker-volume-beegfs

Docker Volume plugin to create persistent volumes in a BeeGFS cluster.

Preconditions

• BeeGFS cluster has to be setup and running
• beegfs-client service needs to be running on the Docker host

Installation

A pre-built binary as well as rpm and deb packages are available from the releases page.

RedHat/CentOS 7

An rpm can be built with:

make rpm

Then install and start the service:

yum localinstall docker-volume-beegfs-$VERSION.rpm
systemctl start docker-volume-beegfs

Debian 8

Debian packages are currently built on a RedHat system, but the Makefile describes which packages to install on Debian when building from scratch. Building the actual package can be done on a Debian system without Makefile modifications:

make deb

Now you can install and start the service:

dpkg -i docker-volume-beegfs_$VERSION.deb
systemctl start docker-volume-beegfs

From source code

The plugin uses govendor to manage dependencies.

go get -u github.com/kardianos/govendor

Restore dependencies:

govendor sync

Build the plugin:

go build

Usage

First create a volume:

docker volume create -d beegfs --name postgres-portroach

Then use the volume by passing the name (postgres-1):

docker run -ti -v postgres-portroach:/var/lib/postgresql/data --volume-driver=beegfs -p 5432:5432 -e POSTGRES_PASSWORD=postgres postgres

Inspect the volume:

docker volume inspect postgres-portroach

Remove the volume (note that this will not remove the actual data):

docker volume rm postgres-portroach

Non-default mount points

By default BeeGFS uses /mnt/beegfs as the mount point (as configured in beegfs-mounts.conf), and this plugin does too. For non-standard mount points you can specify an alternate root when creating a new volume:

docker volume create -d beegfs --name b3 -o root=/stor/b3

Other options are currently silently ignored.
