Question

我有一个基于Python-Flask的应用程序。我希望在客户端访问我的入口端点时获得客户端公共IP。

我已经尝试将externalTrafficPolicy更改为Local和Cluster。

我的Pod YAML文件

apiVersion: v1
kind: Pod
metadata:
  labels:
    run: webplatform
  name: webplatform-deployment-6d68c99fc7-xlb8j
  namespace: prod
spec:
  containers:
  - command:
    - python
    - /app/app.py
    envFrom:
    - secretRef:
        name: webplatform-secret
        optional: false
    image: docker.fuchicorp.com/webplatform-prod:0.5
    imagePullPolicy: Always
    name: webplatform-container
  imagePullSecrets:
  - name: nexus-creds
  serviceAccount: webplatform-service-account
  serviceAccountName: webplatform-service-account

我的服务YAML文件

apiVersion: v1
kind: Service
metadata:
  name: webplatform-service
  namespace: prod
spec:
  externalTrafficPolicy: Cluster
  ports:
  - nodePort: 32744
    port: 7101
    protocol: TCP
    targetPort: 5000
  selector:
    run: webplatform
  sessionAffinity: None
  type: NodePort

我的Ingress资源YAML文件

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    certmanager.k8s.io/cluster-issuer: letsencrypt-fuchicorp-prod
    kubernetes.io/ingress.class: nginx
  generation: 2
  name: ingress-webplaform
  namespace: prod
spec:
  rules:
  - host: academy.fuchicorp.com
    http:
      paths:
      - backend:
          serviceName: webplatform-service
          servicePort: 7101
  tls:
  - hosts:
    - academy.fuchicorp.com
    secretName: letsencrypt-sec-webplatform-prod

当我看到日志时，我看到日志中的Ingress-Controllers IP

INFO: 10.16.0.16 - - [28/Sep/2019 20:06:12] "GET / HTTP/1.1" 200 -

TL; DR

客户端IP应该通过X-Forwarded-For HTTP标头提供

应由负载平衡器（入口控制器）提供。假设您的群集正在云（aws，gcp等）上运行，则可以通过X-Forwarded-For HTTP标头获得客户端IP。

如果它是本地k8s集群（您在自己的私有云/本地计算机上运行），请配置负载均衡器以执行以下操作- http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_next_upstream

如何使客户在Pod上获得公共IP？
