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，我想自动将所有来自 HTTP 的流量重定向到 HTTPS，以便将自己键入域名的人重定向到 HTTPS。我已关注 this page and this one，但我无法使其正常运行

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"

感谢您的支持！ :-)

Answer 1

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

When using SSL offloading outside of cluster (e.g. AWS ELB) it may be useful to enforce a redirect to HTTPS even when there is no TLS certificate is available. This can be achieved by using the nginx.ingress.kubernetes.io/force-ssl-redirect: "true" annotation in the particular resource.

Answer 2

我成功了！！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

我的服务是这样的：

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

我花了很多时间尝试完成这项工作，终于成功了。可能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。

检查您的 ALB 控制器是否启动并且运行ning:

kubectl get deployment -n kube-system aws-load-balancer-controller

打印输出应类似于以下：

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

如果您的控制器不工作，则不会创建负载均衡器。

检查你的yaml文件是否完好。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) 请使用您的图片（我使用的是 YYYYYYYYYY）。我的容器镜像存储在 ECR（Elastic Container Registry）中。
c) 请注意一个奇怪的服务标记为 ssl-redirect with servicePort:
use-annotations 是根据注解规范创建的。
https://kubernetes-sigs.github.io/aws-load-balancer-controller/guide/ingress/annotations/
一旦你运行： kubectl apply -f service.yaml 请检查两件事：
一）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新的 ALB 和两个侦听器。不要注意HTTP侦听器似乎没有正确的重定向配置。

以防万一您正在寻找合适的新语法（其余相同）
