如何使用 Amazon EKS 上的 kubernetes 入口控制器将 http 重定向到 https

Question

我已经为我的应用程序配置了亚马逊证书管理器、ALB 入口控制器和域名。我可以通过端口 80 和端口 443 访问我的应用程序（所有证书都可以正常工作）。但是，我想将所有来自 HTTP 的流量自动重定向到 HTTPS，以便将自己输入域名的人重定向到 HTTPS。我按照这个网页和这一个，但我不能使它工作

这是我的 ingress.yaml 文件：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: metabase
  namespace: bigdata
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-east-2:***:certificate/***
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
    alb.ingress.kubernetes.io/scheme: internet-facing

  labels:
    app: metabase
spec:
  rules:
    - http:
        paths:
          - path: /*
            backend:
              serviceName: ssl-redirect
              servicePort: use-annotation
          - path: /*
            backend:
              serviceName: metabase
              servicePort: 3000

这是我的服务：

apiVersion: v1
kind: Service
metadata:
  name: metabase
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:us-east-2:****:certificate/****
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: http
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "443"
  namespace: bigdata
  labels:
    app: metabase
spec:
  ports:
    - name: https
      protocol: TCP
      port: 443
      targetPort: http-server
    - name: http
      protocol: TCP
      port: 80
      targetPort: http-server
  selector:
    app: metabase
  type: LoadBalancer

广告这是我的部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: metabase-deployment
  namespace: bigdata
  labels:
    app: metabase
spec:
  replicas: 2
  selector:
    matchLabels:
      app: metabase
  template:
    metadata:
      labels:
        app: metabase
    spec:
      containers:
        - name: metabase
          image: metabase/metabase
          ports:
            - containerPort: 3000
              name: http-server
          resources:
            limits:
              cpu: "1"
              memory: "2Gi"

谢谢您的支持！:-)

以防万一您正在寻找正确的新语法（其余部分相同）

      - path: /
        pathType: Prefix
        backend:
          service:
            name: ssl-redirect
            port:
              name: use-annotation

Answer 2

您需要使用nginx.ingress.kubernetes.io/force-ssl-redirect: "true"注释：

在集群外使用 SSL 卸载（例如 AWS ELB）时，即使没有可用的 TLS 证书，强制重定向到 HTTPS 也可能很有用。这可以通过使用nginx.ingress.kubernetes.io/force-ssl-redirect: "true"特定资源中的注释来实现 。

我能够让它工作！基本上我修改了 ingress.yaml 和 service.yaml 文件

ingress.yaml 看起来像这样：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: metabase
  namespace: bigdata
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-east-2:***:certificate/****
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/group: metabase # name of my app

  labels:
    app: metabase

spec:
  rules:
    - http:
        paths:
          - path: /*
            backend:
              serviceName: ssl-redirect
              servicePort: use-annotation
          - path: /*
            backend:
              serviceName: metabase
              servicePort: 443

我的服务如下所示：

apiVersion: v1
kind: Service
metadata:
  name: metabase
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:us-east-2:***:certificate/***
  namespace: bigdata
  labels:
    app: metabase
spec:
  ports:
    - name: https
      protocol: TCP
      port: 443
      targetPort: http-server
    - name: http
      protocol: TCP
      port: 80
      targetPort: http-server
  selector:
    app: metabase
  type: LoadBalancer
