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

问题描述 投票：0回答：7

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，我想自动将所有来自 HTTP 的流量重定向到 HTTPS，以便自行输入域名的人被重定向到 HTTPS。我已关注此页面和此页面但我无法使其工作

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

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"

我能够让它发挥作用！ 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

我的服务看起来像这样：

apiVersion: v1
kind: Service
metadata:
  name: metabase
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:us-east-2:***:certificate/***

      protocol: TCP
      port: 443
      targetPort: http-server
    - name: http
      protocol: TCP
      port: 80
      targetPort: http-server
  selector:
    app: metabase
  type: LoadBalancer

您需要使用

nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
注释：

在集群外部使用 SSL 卸载（例如 AWS ELB）时，可能会出现以下情况： 即使没有 TLS，对于强制重定向到 HTTPS 很有用 证书可用。这可以通过使用来实现 

nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
中的注释 特定资源。

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

我花了相当长的时间尝试完成这项工作，终于成功了。也许有人会发现它很有用。我将尝试逐步描述使用 HTTP 到 HTTPs 重定向设置 ALB 的方法。

  1. 检查您的 ALB 控制器是否已启动并正在运行：
kubectl get deployment -n kube-system aws-load-balancer-controller

打印输出应类似于以下内容：

NAME                           READY   UP-TO-DATE   AVAILABLE   AGE
aws-load-balancer-controller   1/1     1            1           18h

如果您的控制器不起作用，则不会创建负载均衡器。

  1. 检查您的 yaml 文件是否正确。下面我提供了一个适用于我的案例的简单 Yaml 文件。 关于此文件的一些评论：
    a) 请使用您的 SSL/TLS 证书 ARN（我使用 XXXXXXX）。
    b) 请使用您的图像（我使用 YYYYYYYYYY）。我的容器镜像存储在ECR（弹性容器注册表）中。
    c) 请注意，一个奇怪的服务用 servicePort 标记了 ssl-redirect:
    use-annotations 是根据注释规范创建的。
    https://kubernetes-sigs.github.io/aws-load-balancer-controller/guide/ingress/annotations/

  2. 一旦你运行： 

    kubectl apply -f service.yaml
    请检查两件事：
    a) 
    kubectl -n default describe ingress

    此命令应显示协调成功：打印输出的末尾应显示：
    Normal   SuccessfullyReconciled  11s (x3 over 18m)  ingress  Successfully reconciled

    在同一个打印输出中（打印输出的顶部）不要注意日志条目：
    /*   ssl-redirect:use-annotation (<error: endpoints "ssl-redirect" not found>)

    b) 
    aws elbv2 describe-load-balancers --query "LoadBalancers[?contains(LoadBalancerArn,'default-nginx')].{Arn: LoadBalancerArn}" --output text | xargs -I {} aws elbv2 describe-listeners --load-balancer-arn {}

    此命令应向您显示已创建一个新的 ALB 并创建了两个侦听器。不要注意 HTTP 侦听器的作用 似乎没有正确的重定向配置。

以下解决方案对我们有用。

nginx.ingress.kubernetes.io/force-ssl-redirect：“true”
