I'm trying to set up a Kubernetes cluster on GCE using CoreOS as the base OS. But I'm having the following issue when trying to make the cluster a multizone cluster by setting the --cloud-provider and --cloud-config flags.

The below is the output from the API Server on the master node:

Jun 15 09:22:09 cos-000-pub-pvt-master.c.project-id.internal kubelet-wrapper[1098]: E0615 09:22:09.790068    1098 gce.go:2380] Failed to retrieve instance: "10.0.0.2"

Jun 15 09:22:09 cos-000-pub-pvt-master.c.project-id.internal kubelet-wrapper[1098]: E0615 09:22:09.790151    1098 kubelet.go:1131] Unable to construct api.Node object for kubelet: failed to get external ID from cloud provider: instance not found

When running kubectl get nodes there is no output, but when running kubectl --namespace kube-system get pods I see the API Server, Controller Manager, Scheduler and each of the Proxies for each of the nodes. Although I can see them they are restarted every 45-60 seconds.

The GCE config file is as follows:

[GLOBAL]
multizone=true

If I've left something out that can help let me know.
