Run the following command to deploy the east-west gateway to a primary cluster:

```bash
export MESH=mesh1
export CLUSTER=cluster1
export NETWORK=network1
./samples/multicluster/gen-eastwest-gateway.sh | \
    istioctl manifest generate -f - | \
    kubectl apply -f -
```

The `CLUSTER` and `NETWORK` environment variables should match the values used to deploy the control plane
in that cluster.
