Create the external load balancer network resources step drops these errors.

Seems like you already have the 'kubernetes-target-pool' created, so you could try deleting the same via commandline, or go to the GCP dashboard, search for it and delete.

I have a similar problem here.

Here is my output:

johns-mbp:~ jstoveld$ gcloud compute addresses create kubernetes-the-hard-way   --region $(gcloud config get-value compute/region)

@organicnz looks like you are trying to create LB resource from controller instance instead of local machine:

organic@controller-0:~$ {

Note that:

The compute instances created in this tutorial will not have permission to complete this section. Run the following commands from the same machine used to create the compute instances.
