Docker w/GlusterFS volume driver on Scaleway C1 servers

instructions.sh

# 0. For the server, use the "Docker" base image from the ImageHub (https://www.scaleway.com/de/imagehub/docker/)

# 1. Install https://github.com/calavera/docker-volume-glusterfs
# Alternatively, just download the prebuilt executable from https://gobuilder.me/get/github.com/calavera/docker-volume-glusterfs/docker-volume-glusterfs_master_linux-arm.zip 
apt-get -y install golang
export GOPATH=~/go
go get github.com/calavera/docker-volume-glusterfs
mv go/bin/docker-volume-glusterfs /usr/local/bin/

# 2. Install GlusterFS
apt-get install -y glusterfs-server

# 3. Now, start the docker-volume-glusterfs plugin
modprobe fuse
docker-volume-glusterfs -servers 127.0.0.1

# Repeat steps 1-3 on as many servers as you like.

# 4. Create Gluster volume 
LOCAL_IP=$(ip a show dev eth0 scope global | grep inet | awk -F '[ /]*' '{print $3}')
gluster volume create datastore ${LOCAL_IP}:/datastore force
gluster volume set datastore nfs.disable true
gluster volume set datastore auth.allow 127.0.0.1

# 5. Adding a second GlusterFS server
# From the first server:
glustr peer probe <INTERNAL IP OF 2ND SERVER>
gluster volume add-brick datastore replica 2 <INTERNAL IP OF 2ND SERVER>:/datastore force

# 6. Done! Try out the volume on each server:
@server1 $ docker run --volume-driver glusterfs --volume datastore:/data armhfbuild/alpine:3.1 echo hello >/data/test
@server2 $ docker run --volume-driver glusterfs --volume datastore:/data armhfbuild/alpine:3.1 cat /data/test

# To come: SSL for GlusterFS
