Documentation

Overview

This version of Photon cloud provider supports the disk interface for Photon persistent disk volume plugin. LoadBalancer, Routes, and Zones are currently not supported. The use of Photon cloud provider requires to start kubelet, kube-apiserver, and kube-controller-manager with config flag: '--cloud-provider=photon --cloud-config=[path_to_config_file]'. When running multi-node kubernetes using docker, the config file should be located inside /etc/kubernetes.
