This plugin uses GlusterFS as distributed data storage for containers.
Using go (until we get proper binaries):
$ go get github.com/amarkwalder/docker-volume-glusterfs
This plugin doesn't create volumes in your GlusterFS cluster yet, so you'll have to create them yourself first.
1 - Start the plugin using this command:
$ sudo docker-volume-glusterfs -servers gfs-1:gfs-2:gfs-3
We use the flag -servers to specify where to find the GlusterFS servers. The server names are separated by colon.
2 - Start your docker containers with the option --volume-driver=glusterfs and use the first part of --volume to specify the remote volume that you want to connect to:
$ sudo docker run --volume-driver glusterfs --volume datastore:/data alpine touch /data/helo
See this video for a slightly longer usage explanation:
This extension can create volumes on the remote cluster if you install https://github.com/dangzhiqiang/glusterfs-rest in one of the nodes of the cluster.
You need to set two extra flags when you start the extension if you want to let containers to create their volumes on demand:
- rest: is the URL address to the remote api.
- gfs-base: is the base path where the volumes will be created.
This is an example of the command line to start the plugin:
$ docker-volume-glusterfs -servers gfs-1:gfs2 \
-rest http://gfs-1:9000 -gfs-base /var/lib/gluster/volumes
These volumes are replicated among all the peers in the cluster that you specify in the -servers flag.
For Systemd based distros, use the files in contrib/systemd.
mv docker-volume-glusterfs /usr/local/bin/
mv contrib/systemd/etc/systemd/system/docker-volume-glusterfs.service /etc/systemd/system/
mv contrib/systemd/etc/sysconfig/docker-volume-glusterfs.conf /etc/sysconfig/
systemctl daemon-reload
Edit the file /etc/sysconfig/docker-volume-glusterfs.conf` with your config
systemctl start docker-volume-glusterfs && systemctl enable docker-volume-glusterfs
