docker-glusterfs

This docker is used to create a glusterfs cluster. This creates a node (brick) for gluster fs.

Status : unstable, early alpha.

Quick start

image you have a plateform with 3 servers named data1, data2 and data3.

In your /etc/hosts of each server, you have the definition of the servers

10.0.0.101 data1
10.0.0.102 data2
10.0.0.103 data3

1. run the gluster daemon on each node

data1 has to be replaced by data2 or data3 for the GLUSTER_BRICK env var.

for server in data1 data2 data3; do
    ssh root@${server} "
        docker rm glusterfs ; \
        docker run -d --name=glusterfs --privileged=true \
            --net=host \
            --env GLUSTER_PEER=${server} \
            --env GLUSTER_VOLUME=my_volume \
            --env GLUSTER_PEER_LIST='data1|data2|data3' \
            --volume /etc/hosts:/etc/hosts:ro \
            --volume /var/gluster/data:/gluster_data \
            kitpages/docker-glusterfs /usr/local/bin/run_daemon.sh \
    "
done

2. probe all daemons.

on each nodes

for server in data1 data2 data3; do
    ssh root@${server} "
        docker exec -i glusterfs /usr/local/bin/probe_other_peers.sh
    "
done

3. start the volume

On anyone of the nodes

docker exec -i glusterfs /usr/local/bin/start_volume.sh

4. connect the client to the cluster
