 This feature is able to deliver by adding parameters to kube-controller-manager and kubelet. You need specify:
 
-	--cloud-provider=gce
-	--cloud-config=/etc/kubernetes/cloud-config
+    --cloud-provider=gce
+    --cloud-config=/etc/kubernetes/cloud-config
 
 To get working it in kubespray, you need to add tag to GCE instances and specify it in kubespray group vars and also set cloud_provider to gce. So for example, in file group_vars/all/gcp.yml:
 
-	cloud_provider: gce
-	gce_node_tags: k8s-lb
+    cloud_provider: gce
+    gce_node_tags: k8s-lb
 
 When you will setup it and create SVC in Kubernetes with type=LoadBalancer, cloud provider will create public IP and will set firewall.
 Note: Cloud provider run under VM service account, so this account needs to have correct permissions to be able to create all GCP resources.
