google 在 gke 上找不到云端点 api_method

Question

404 响应 Method: 1.api_endpoints_gcp_project_cloud_goog.Postoperation failed: NOT_FOUND google 云端点 esp

我正在尝试通过 GKE 将我的 API 与 google 云端点部署在一起。我在 Produced API 日志中收到此错误，其中显示：

Method: 1.api_endpoints_gcp_project_cloud_goog.Postoperation failed: NOT_FOUND

我从端点收到 404 响应。

后端容器正确回答，但是当我尝试 post http://[service-ip]/v1/postoperation 时出现 404 错误。我猜它与 api_method 名称有关，但我已经更改，所以它在 openapi.yaml、gke 部署和 app.py.

中是相同的

我使用 openapi.yaml:

成功部署了 API 服务

swagger: "2.0"

      produces:

      responses:
        200:

          schema:
            $ref: "#/definitions/Model"
        400:
          description: "Error"
      parameters:
      - description: "Description"
        in: body
        name: payload
        required: true
        schema:
          $ref: "#/definitions/Resource"

definitions:
  Resource:
    type: "object"
    required:
    - "text"
    properties:
      tipodni:
        type: "string"
      dni:
        type: "string"
      text:
        type: "string"

  Model:
    type: "object"
    properties:
      tipodni:
        type: "string"
      dni:
        type: "string"
      text:
        type: "string"
      mundo:
        type: "string"
      cluster:
        type: "string"
      equipo:
        type: "string"
      complejidad:
        type: "string"

然后我尝试用这个 deploy.yaml 和 lb-deploy.yaml

配置后端和 esp

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
  name: api-deployment
  namespace: development
spec:
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: api1
  replicas: 2 # tells deployment to run 2 pods matching the template
  template:
    metadata:
      labels:
        app: api1
    spec:
      volumes:
        - name: google-cloud-key
          secret:
            secretName: secret-key

      containers:
      - name: api-container
        image: gcr.io/gcp-project/docker-pqr:IMAGE_TAG_PLACEHOLDER
        volumeMounts:
        - name: google-cloud-key
          mountPath: /var/secrets/google
        ports:
        - containerPort: 5000

      - name: esp
        image: gcr.io/endpoints-release/endpoints-runtime:1
        args: [
          "--http_port=8081",
          "--backend=127.0.0.1:5000",
          "--service=api.endpoints.gcp-project.cloud.goog",
          "--rollout_strategy=managed"
        ]
        ports:
        - containerPort: 8081

kind: Service
metadata:
  name: "api1-lb"
  namespace: development
  annotations:
    cloud.google.com/load-balancer-type: "Internal"
spec:

  #  loadBalancerIP: "172.30.33.221"
  selector:
    app: api1
  ports:
  - protocol: TCP
    port: 80
    targetPort: 8081

我为 api 服务的 Flask 应用程序是这个 app.py

app = Flask(__name__)

categorizador = Categorizador(model_properties.paths)

@app.route('/postoperation', methods=['POST'])
def postoperation():

    text = request.get_json().get('text', '')
    dni = request.get_json().get('dni', '')
    tipo_dni = request.get_json().get('tipo_dni', '')

    categoria,subcategoria = categorizador.categorizar(text)

    content = {
        'tipodni': tipo_dni,
        'dni': dni,
        'text': text,
        'mundo': str(categoria),
        'cluster': str(subcategoria),
        'equipo': '',
        'complejidad': ''
    }

    return jsonify(content)

Answer 1

来自kubectl expose -h

的一些位

--port='' - 服务应该服务的端口。从公开的资源中复制，如果未指定
--target-port='' - 服务应将流量定向到的容器上端口的名称或编号。可选。

当代理将您的流量定向到 --backend=127.0.0.1:5000 时，请使用容器名称 isstead --backend=api-container:5000。

Answer 2

看来您需要在 Flask 应用中配置路由。试试这个：

@app.route('/v1/postoperation', methods=['POST'])
