无法从运行在Istio中的节点容器访问Mongo

Question

我试图在Kubernetes内运行一个有状态的Mongo，它可以在Istio之外使用这些配置。

mongodb: { 
    uri: "mongodb://mongo-0.mongo,mongo-1.mongo,mongo-2.mongo", 
    dbName: "app" 
    } 

但是当我在Istio中运行节点应用程序时，它失去了连接到mongo的能力。有什么我错过了，或者是我不能在Istio中使用有状态集？

stateful mongo config below。那我收到

apiVersion: v1 
kind: Service 
metadata: 
    labels: 
    service: mongo 
    name: mongo 
spec: 
    ports: 
    - name: tcp 
    port: 27017 
    targetPort: 27017 
    clusterIP: None 
    selector: 
    service: mongo 
    role: mongo 
*********** 
apiVersion: apps/v1beta1 
kind: StatefulSet 
metadata: 
    name: mongo 
spec: 
    serviceName: "mongo" 
    replicas: 3 
    template: 
    metadata: 
     labels: 
     role: mongo 
     environment: test 
     service: mongo 
    spec:

     containers: 
     - name: mongo 
      image: mongo:3.4.6 
      resources: 
      requests: 
       cpu: "10m" 
      command: 
      - mongod 
      - "--replSet" 
      - rs0 
      - "--smallfiles" 
      - "--noprealloc" 
      ports: 
      - containerPort: 27017 
      volumeMounts: 
      - name: mongo-persistent-storage 
       mountPath: /data/db 
     - name: mongo-sidecar 
      image: cvallance/mongo-k8s-sidecar 
      resources: 
      requests: 
       cpu: "10m" 
      env: 
      - name: MONGO_SIDECAR_POD_LABELS 
       value: "role=mongo,environment=test" 

错误是

[2017-07-25 12:01:11] ERROR Mongoose MonboDB connection error: { 
    "message": "write EPIPE", 
    "name": "MongoError", 
    "stack": "Error: write EPIPE\n at exports._errnoException (util.js:1024:11)\n at WriteWrap.afterWrite [as oncomplete] (net.js:851:14)"

StatefulSet支持是刚加入的，但它不是一个版本呢。
