Chapter 16. Configuring for GCE

16.1. Overview

OpenShift Enterprise can be configured to access an GCE infrastructure, including using GCE volumes as persistent storage for application data. After GCE is configured properly, some additional configurations will need to be completed on the OpenShift Enterprise hosts.

16.2. Configuring Masters

Edit or create the master configuration file on all masters (/etc/origin/master/master-config.yaml by default) and update the contents of the apiServerArguments and controllerArguments sections: 

kubernetesMasterConfig:
  ...
  apiServerArguments:
    cloud-provider:
      - "gce"
  controllerArguments:
    cloud-provider:
      - "gce"
Important

When triggering a containerized installation, only the directories of /etc/origin and /var/lib/origin are mounted to the master and node container. Therefore, master-config.yaml should be in /etc/origin/master instead of /etc/.

16.3. Configuring Nodes

Edit or create the node configuration file on all nodes (/etc/origin/node/node-config.yaml by default) and update the contents of the kubeletArguments section: 

kubeletArguments:
  cloud-provider:
    - "gce"
Important

When triggering a containerized installation, only the directories of /etc/origin and /var/lib/origin are mounted to the master and node container. Therefore, node-config.yaml should be in /etc/origin/node instead of /etc/.

Then, start or restart the OpenShift Enterprise services on the master and all nodes.
