This is unreleased documentation for SUSE® Rancher Manager v2.11 (Unreleased).

Setting up the Google Compute Engine Cloud Provider

In this section, you’ll learn how to enable the Google Compute Engine (GCE) cloud provider for custom clusters in Rancher. A custom cluster is one in which Rancher installs Kubernetes on existing nodes.

The official Kubernetes documentation for the GCE cloud provider is here.

Prerequisites:

The service account of Identity and API access on GCE needs the Computer Admin permission.

If you are using Calico,

  1. Click ☰ > Cluster Management.

  2. On the Clusters page, go to the custom cluster and click *⋮ > Edit YAML. Enter the following configuration:

     rancher_kubernetes_engine_config:
   cloud_provider:
     name: gce
     customCloudProvider: |-
       [Global]
       project-id=<your project ID, optional>
       network-name=<your network, optional if using default network>
       subnetwork-name=<your subnetwork of the above network, optional if using default network>
       node-instance-prefix=<your instance group name/your instance name specific prefix, required>
       node-tags=<your network tags, must patch one or some tags, required>
   network:
     options:
       calico_cloud_provider: "gce"
     plugin: "calico"

If you are using Canal or Flannel,

  1. Click ☰ > Cluster Management.

  2. On the Clusters page, go to the custom cluster and click *⋮ > Edit YAML. Enter the following configuration:

     rancher_kubernetes_engine_config:
   cloud_provider:
     name: gce
     customCloudProvider: |-
       [Global]
       project-id=<your project ID, optional>
       network-name=<your network, optional if using default network>
       subnetwork-name=<your subnetwork of the above network, optional if using default network>
       node-instance-prefix=<your instance group name/your instance name specific prefix, required>
       node-tags=<your network tags, must patch one or some tags, required>
