Creating instance groups

Create two unmanaged instance groups in ZONE_1 and ZONE_2. Each group will contain the FortiGate instance from the respective zone.

To create instance groups:

1. Create an unmanaged instance group: gcloud compute instance-groups unmanaged create fgt-umig1--zone=$ZONE1
2. Add a VM instance to the instance group:

   gcloud compute instance-groups unmanaged add-instances fgt-umig1 \
     --instances=example-vm-fgt1 \
     --zone=ZONE_1
   

3. Repeat steps 1 and 2 for the second zone.
