GCP Load Balancers for type=LoadBalacer of Kubernetes Services

Google Cloud Platform can be used for creation of Kubernetes Service Load Balancer.

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

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

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.
