The next step is create the pod routing rules to allow pods to communicate with one another.

These rules are set up on the Google Compute Engine - and use values from the environment variables specified at the start.

This should be very straightforward, and a summary of the rules created should be printed when the script finishes, which should look similar to:

NAME                            NETWORK     DEST_RANGE     NEXT_HOP                  PRIORITY
