Google Healthcare API on GKE with PubSub - INVALID_ARGUMENT

Question

我们一直在测试Google Healthcare API，特别是在HL7上，当我浏览教程的时候，我遇到了一个障碍。值得一提的是，我对Kubernetes和AWS有相当多的经验，但没有太多的Google Cloud。

下面这一步给我带来了麻烦：

https://cloud.google.com/healthcare/docs/how-tos/mllp-adapter#creating_a_compute_engine_vm_and_sending_messages

当我尝试从VM发送消息时，我没有看到响应，pod中的日志显示以下错误：

I0411 17:27:33.756432       1 healthapiclient.go:163] Dialing connection to https://healthcare.googleapis.com:443/v1beta1

{
  "error": {
    "code": 400,
    "message": "location ID invalid, expected us-central1",
    "status": "INVALID_ARGUMENT"
  }
}
I0411 17:27:58.880691       1 mllpreceiver.go:119] Closed connection from 10.128.0.5:58698

此错误令人费解，因为GKE集群和VM位于同一区域/区域。有没有人遇到过MLLP适配器和GKE的类似问题？

Answer 1

HL7v2存储的路径(在yaml，hl7_v2_location_id中)中的location id参数可能丢失或不正确；错误看起来像是从MLLP适配器对Cloud Healthcare API的请求引发的，而不是任何特定于GKE的请求。

Answer 2

问题是我指定位置/区域的方式：

最初我的模板是这样的：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: mllp-adapter-deployment
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: mllp-adapter
    spec:
      containers:
        - name: mllp-adapter
          imagePullPolicy: Always
          image: gcr.io/cloud-healthcare-containers/mllp-adapter
          ports:
            - containerPort: 2575
              protocol: TCP
              name: "port"
          command:
            - "/usr/mllp_adapter/mllp_adapter"
            - "--port=2575"
            - "--hl7_v2_project_id=XXXXXXXXXXXXX"
            - "--hl7_v2_location_id=us-central1-b"
            - "--hl7_v2_dataset_id=XXX-test-set"
            - "--hl7_v2_store_id=hlstore"
            - "--api_addr_prefix=https://healthcare.googleapis.com:443/v1beta1"
            - "--logtostderr"
            - "--receiver_ip=0.0.0.0"
            - "--pubsub_project_id=XXXXXXXX-api-dev"
            - "--pubsub_subscription=XX-incomingsub"

并且location_id需要这样指定：

- "--hl7_v2_location_id=us-central1"

谢谢。
