## Prerequisites ## Prerequisites
The commands in this lab must be run on each controller instance: `controller-0`, `controller-1`, and `controller-2`. Login to each controller instance using the `gcloud` command. Example: First, we need to add an extra firewall rule to allow the `etcd` nodes on the controller instances to talk to each other:

``` ```
gcloud compute ssh controller-0 gcloud compute ssh controller-0
