 First you should create a Kubernetes cluster in your GKE, then make sure your KUBECONFIG is ready in `~/.kube/config`, if not, you can run following commands,
 ``` shell
 $ gcloud auth login
 $ gcloud container clusters get-credentials <your cluster> --zone <zone> --project <project>
 ```
 Then make sure you current context is GKE cluster, you can check it with command,
 ``` shell
 $ kubectl config current-context

 Then you can deploy your function onto GKE cluster with,
 ```shell
 $ KUBECONFIG=~/.kube/config fx up examples/functions/JavaScript/func.js --name hellojs

  my $a = $ctx->req->json->{"a"};
  my $b = $ctx->req->json->{"b"};
  return int($a) + int($b)
 }
 1;
 ```
 ```shell
 fx up --name add --port 40002 --force add.pl
