...dó cũng bao gồm `uvicorn`, bạn có thể sử dụng như một server để chạy code của bạn.

!!! note
    Bạn cũng có thể cài đặt nó từng phần.

    Đây là những gì bạn có thể sẽ làm một lần duy nhất bạn muốn triển khai ứng dụng của bạn lên production:

    ```
    pip install fastapi
    ```

    Cũng cài đặt `uvicorn` để làm việc như một server:

    ```

```bash
kubectl wait --for=condition=ready gtw helloworld-gateway
export INGRESS_HOST=$(kubectl get gtw helloworld-gateway -o jsonpath='{.status.addresses[*].value}')
```

Confirm the sample is running using curl:

```bash
for run in {1..10}; do curl http://$INGRESS_HOST/hello; done
```

Since no version routing has been configured, you should see an equal split of traffic, about half handled by helloworld-v1 and the other half handled by helloworld-v2.

  successThreshold: 1
  failureThreshold: 3
```

## Cluster probe

### Cluster-writeable probe

The reply is '200 OK' if cluster has write quorum if not it returns '503 Service Unavailable'.

```
curl http://minio1:9001/minio/health/cluster
HTTP/1.1 503 Service Unavailable
Accept-Ranges: bytes
Content-Length: 0
Server: MinIO
Vary: Origin
X-Amz-Bucket-Region: us-east-1
X-Minio-Write-Quorum: 3

            return false;
        }
        int idx = 0;
        Trie cur = this;
        while (idx < seq.length()) {
            char c = seq.charAt(idx);
            boolean found = false;
            for (Trie transition : cur.transitions) {
                if (transition.c == c) {
                    cur = transition;
                    idx++;
                    found = true;

}
```

Note the expiration date (`exp`) is very long in the future, so it can be tested as is without any modification. For example:

```bash
TOKEN=$(curl https://raw.githubusercontent.com/istio/istio/master/security/tools/jwt/samples/demo.jwt -s)
curl --header "Authorization: Bearer $TOKEN" $INGRESS_HOST/headers -s -o /dev/null -w "%{http_code}\n"
```

Alternatively, you can use the `gen-jwt.py` script to create new test token:

    dictionaries.
  """
  real_parameters = []
  for parameters in test_parameters:
    keys = parameters.keys()
    for curr in itertools.product(*parameters.values()):
      real_parameters.append(dict(zip(keys, curr)))
  return real_parameters

		exit 1
