This example starts up 2 rgws on the host that will pull the realm from the rgws on rgw-001 above. `rgw3` is pulling from the rgw endpoint in realm usa in the master zone example above (instance name rgw1). `rgw4` is pulling from the rgw endpoint in realm france in the master zone example above (instance name rgw2).
