Istio Ingress Controller不保留客户端原始IP

我们正在使用Istio 0.7和istio ingress控制器来处理外界的要求 . 我们使用“ClusterIP”类型服务的“externalIPs”属性来暴露kubernetes之外的入口控制器 .

Istio Ingress Controller Yaml:

apiVersion: v1
kind: Service
metadata:
  name: istio-ingress-3
  namespace: istio-system
  labels:
    istio: ingress
spec:
  ports:
  - port: 80
    name: http
  - port: 443
    name: https
  externalIPs:
  - 192.168.X.X
  selector:
    istio: ingress-3
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: istio-ingress-3
  namespace: istio-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        istio: ingress-3
      annotations:
        sidecar.istio.io/inject: "false"
    spec:
      nodeSelector:
        kubernetes.io/hostname: node3.example.com
      serviceAccountName: istio-ingress-service-account
      containers:
      - name: istio-ingress
        image: docker.io/istio/proxy:0.7.1
        args:
        - proxy
        - ingress
        - --discoveryAddress
        - istio-pilot:8080 #--controlPlaneAuthPolicy
        - --discoveryRefreshDelay
        - '1s' #discoveryRefreshDelay
        - --drainDuration
        - '45s' #drainDuration
        - --parentShutdownDuration
        - '1m0s' #parentShutdownDuration
        - --connectTimeout
        - '10s' #connectTimeout
        - --serviceCluster
        - istio-ingress
        - --zipkinAddress
        - zipkin:9411
        - --statsdUdpAddress
        - istio-mixer:9125
        - --proxyAdminPort
        - "15000"
        - --controlPlaneAuthPolicy
        - NONE #--controlPlaneAuthPolicy
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80
        - containerPort: 443
        env:
        - name: POD_NAME
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.name
        - name: POD_NAMESPACE
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.namespace
        volumeMounts:
        - name: istio-certs
          mountPath: /etc/certs
          readOnly: true
        - name: ingress-certs
          mountPath: /etc/istio/ingress-certs
          readOnly: true
      volumes:
      - name: istio-certs
        secret:
          secretName: istio.istio-ingress-service-account
          optional: true
      - name: ingress-certs
        secret:
          secretName: istio-ingress-certs
          optional: true

问题是每当我们在触发请求后检查入口控制器的日志时它会给出我们在外部ip（主机ip）中给出的相同的ip . 但我们希望客户原始信息如客户原始IP

What you expected to happen:

我们想要原始客户端IP而不是外部IP中给出的IP即（192.168.X.X） .

Additional Information

我已在互联网上查看并发现使用“externalTrafficPolicy：Local”标志我们可以保留客户端IP，但此标志仅在NodePort类型服务中有效 . 我们不想使用NodePort服务，因为如果我们使用它，它将打开我们的入口控制器，用于私有和公共主机的所有接口 .

Kubernetes version

客户端版本：version.Info {Major：“1”，Minor：“10”，GitVersion：“v1.10.1”，GitCommit：“d4ab47518836c750f9949b9e0d387f20fb92260b”，GitTreeState：“clean”，BuildDate：“2018-04-12T14：26 ：04Z“，GoVersion：”go1.9.3“，编译器：”gc“，平台：”linux / amd64“}服务器版本：version.Info {Major：”1“，Minor：”10“，GitVersion：”v1 . 10.3 coreos.0“，GitCommit：”f1b890dbbf11abe58280b3ffe17d67749f5ae70e“，GitTreeState：”clean“，BuildDate：”2018-05-21T17：27：17Z“，GoVersion：”go1.9.3“，编译：”gc“，平台：”linux / AMD64" }

OS (e.g. from /etc/os-release)

NAME =“CoreOS的容器Linux”ID = coreos VERSION = 1745.5.0 VERSION_ID = 1745.5.0 BUILD_ID = 2018-05-31-0701 PRETTY_NAME =“CoreOS 1745.5.0（流纹岩）的容器Linux”ANSI_COLOR =“38; 5; 75“HOME_URL =”https://coreos.com/“BUG_REPORT_URL =”https://issues.coreos.com“COREOS_BOARD =”amd64-usr“

Kernel (e.g. uname -a)

Linux node1.example.com 4.14.44-coreos-r1＃1 SMP Thu May 31 06:04:02 UTC 2018 x86_64 Intel（R）Xeon（R）CPU L5640 @ 2.27GHz GenuineIntel GNU / Linux

有人可以帮助我们吗？
