running multiple k8s clusters it is important to proivde different values for each cluster
to avoid overlapping addresses.

For example, to create two clusters, run the script two times with the following
parameters:

```bash
  ./setupkind.sh --cluster-name cluster1 --ip-space 255 -i dual
  ./setupkind.sh --cluster-name cluster2 --ip-space 245 -i dual
```

points to the public IP address where each cluster might be accessible, this is unique for each cluster.

NOTE: `mybucket` only exists on one cluster either `cluster1` or `cluster2` this is random and
is decided by how `domain.com` gets resolved, if there is a round-robin DNS on `domain.com` then
it is randomized which cluster might provision the bucket.
