Google Kubernetes Engine

The configuration yaml will be slight different for Google Kubernetes Engine (GKE):

1. GKE requires user to manually claim himself as cluster admin to enable RBAC. User need to execute following command before create the Longhorn system using yaml files.

kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=<name@example.com>

In which name@example.com is the user's account name in GCE, and it's case sensitive. See here for details.

2. The default Flexvolume plugin directory is different with GKE 1.8+, which is at /home/kubernetes/flexvolume. User need to use following command instead:

FLEXVOLUME_DIR="/home/kubernetes/flexvolume/"
curl -s https://raw.githubusercontent.com/rancher/longhorn/v0.3-rc/deploy/longhorn.yaml|sed "s#^\( *\)value: \"/var/lib/kubelet/volumeplugins\"#\1value: \"${FLEXVOLUME_DIR}\"#g" > longhorn.yaml
kubectl create -f longhorn.yaml

See Troubleshooting for details.
