Can I create GKE cluster nodes without external IP addresses?

I noticed that all nodes created by GKE have ephemeral external IP addresses.

Is it necessary and can be disabled? I would prefer not to publish all sites publicly.

Yes. GCE VM requires an external IP address to send outgoing requests to the Internet, which includes the GCE API. Without external IP addresses, virtual machines will not be able to connect to the cluster management plane (Cuban-Cuban), docker hub, gcr.io, etc.

Can I turn it off?

Not at present.

Just a quick comment for a future traveler. This is not yet possible, but they are working on it.

Does anyone know if this can be resolved using NAT Gateway, as in this example ?
