In this lab you will bootstrap 3 Kubernetes worker nodes. The following virtual machines will be used:
```
NAME ZONE MACHINE_TYPE INTERNAL_IP STATUS
worker0 us-central1-f n1-standard-1 10.240.0.30 RUNNING
worker1 us-central1-f n1-standard-1 10.240.0.31 RUNNING
worker2 us-central1-f n1-standard-1 10.240.0.32 RUNNING
gcloud compute instances list
```
