Deployment

Integration test

See longhorn-tests repo

Notes:
Google Kubernetes Engine

You will need to create cluster-admin role binding for yourselves before creating the deployment, see here for details.

ctl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=<name@example.com>
Flexvolume Plugin Directory

By default we're using the default Flexvolume Plugin directory, which is /usr/libexec/kubernetes/kubelet-plugins/volume/exec/.

For GKE 1.8+, it should be at: /home/kubernetes/flexvolume.

You may need to change deploy/deploy.yaml volume flexvolume-longhorn-mount location according to your own environment.
