ssl - Kubernetes 入口 : SSL (HTTP -> HTTPS) redirect not working (Nginx Docker)

Question

我在 Google Cloud Kubernetes Engine 中使用 Kubernetes 并设置了以下内容:- Nginx docker 镜像 (nginx:latest)，它托管了一个网络应用程序- Kubernetes 部署(yaml 文件)- Kubernetes 服务(yaml 文件)- 具有现有 key 和证书的 Kubernetes Secret(通配符 PositiveSSL)- Kubernetes 入口

目前我同时使用 HTTP 和 HTTPS。但是，我想自动将所有 HTTP 调用重定向到 HTTPS，但似乎无法正常工作。

我已经尝试了下面的 conf 和脚本文件的许多变体，但它似乎无法将 HTTP 重定向到 HTTPS。

知道我在这里做错了什么吗？

请参阅下面的 conf、yaml 和 docker 文件。

Nginx session :

server {
  listen 80;
  charset utf-8;
  root /usr/share/nginx/html;

  location / {
    proxy_set_header        Host $host:$server_port;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;
    proxy_redirect  http:// https://;
    proxy_pass              http://portal.domain.com;
    proxy_http_version 1.1;
    proxy_request_buffering off;
  }
}

server {
  listen 443 ssl;

  charset utf-8;
  root /usr/share/nginx/html;

  ssl_certificate       /etc/nginx/ssl/domain_com_full.crt;
  ssl_certificate_key   /etc/nginx/ssl/domain_com.key;

  location / {
    proxy_set_header        Host $host:$server_port;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;
    proxy_redirect  http:// https://;
    proxy_pass              http://portal.domain.com;
    proxy_http_version 1.1;
    proxy_request_buffering off;
  }
}

Docker 文件:

FROM nginx:latest
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY domain_com_full.crt /etc/nginx/ssl/domain_com_full.crt
COPY domain_com.key /etc/nginx/ssl/domain_com.key
COPY dist /usr/share/nginx/html
EXPOSE 443 80

部署YAML(我用脚本填写镜像的修改部分):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: domain-frontend-prd
spec:
  replicas: 2
  strategy:
    type: RollingUpdate
    rollingUpdate:
        maxSurge: 1
        maxUnavailable: 0
  selector:
    matchLabels:
      run: domain-frontend-prd
  template:
    metadata:
      labels:
        run: domain-frontend-prd
    spec:
      containers:
      - name: domain-frontend-image
        image: eu.gcr.io/domain-service/domain-frontend-image:{{REVISION_ID}}
        ports:
        - containerPort: 80
        - containerPort: 443
        readinessProbe:
          httpGet:
            path: /
            port: 80
          initialDelaySeconds: 5
          periodSeconds: 5
          successThreshold: 1

服务 YAML:

apiVersion: v1
kind: Service
metadata:
  name: domain-frontend-service-prd
spec:
  type: NodePort
  selector:
    run: domain-frontend-prd
  ports:
  - protocol: TCP
    port: 443
    targetPort: 443
    name: https-port
  - protocol: TCP
    port: 80
    targetPort: 80
    name: http-port

Ingress YAML( secret 有效，因为 HTTPS 调用也有效 + 静态 IP 也在那里并有效):

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: domain-frontend-ingress-prd
  annotations:
    kubernetes.io/ingress.global-static-ip-name: kubernetes-ingress
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
spec:
  tls:
  - hosts:
    - portal.domain.com
    secretName: domain-tls
  backend:
    serviceName: domain-frontend-service-prd
    servicePort: 80
  rules:
  - host: portal.domain.com
    http:
      paths:
        - path: /
          backend:
            serviceName: domain-frontend-service-prd
            servicePort: 80

Answer 1

通过广泛的搜索，我发现 Google Cloud Kubernetes 引擎中的标准 Ingress Controller 显然不支持重定向到 HTTPS。

为了能够将流量重新发送到 HTTPS(从 HTTP)，您需要根据本教程/文档安装 NGINX Ingress Controller :

这解决了我的问题。
