Traefik (v2.2) Ingress on Kubernetes：HTTP 和 HTTPS 不能共存

Question

我在 Kubernetes 上使用 Traefik (v2.2)，使用通配符域证书进行 HTTPS 访问。

以下是我的Traefik部署和Ingress配置：

kind: Deployment
apiVersion: apps/v1
metadata:
  namespace: ingress-traefik
  name: traefik
  labels:
    app: traefik

spec:
  replicas: 1
  selector:
    matchLabels:
      app: traefik
  template:
    metadata:
      labels:
        app: traefik
    spec:
      serviceAccountName: traefik-ingress-controller
      containers:
        - name: traefik
          image: traefik:v2.2
          ports:
            - name: web
              containerPort: 80
            - name: websecure
              containerPort: 443
            - name: admin
              containerPort: 8080
          args:
            - --providers.kubernetesingress
            - --entrypoints.web.Address=:80
            - --entrypoints.websecure.Address=:443
            - --ping.entryPoint=web

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-ingress
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/router.entrypoints: web, websecure

    # remark the following line, HTTPS will return "404 page not found"
    # enable the following line, HTTP will return "404 page not found"
    traefik.ingress.kubernetes.io/router.tls: "true"

    cert-manager.io/cluster-issuer: letsencrypt-prod

spec:
  tls:
    - secretName: cert-stage-wildcard

  rules:
    - host: user.example.io
      http:
        paths:
        - path: /
          backend:
            serviceName: user-service
            servicePort: http

我想同时使用 HTTP 和 HTTPS，但似乎不能同时使用：

如果我注释掉 ingress 的注解 'traefik.ingress.kubernetes.io/router.tls: "true"'，HTTP 会工作，但 HTTPS 不会：

$ curl -v https://user.example.io
*   Trying 159.203.52.215:443...
* TCP_NODELAY set
* Connected to user.example.io (159.203.52.215) port 443 (#0)
* ALPN, offering http/1.1
* successfully set certificate verify locations:

*  subjectAltName: host "user.example.io" matched cert's "*.example.io"
*  issuer: C=US; O=Let's Encrypt; CN=Let's Encrypt Authority X3
*  SSL certificate verify ok.
> GET / HTTP/1.1

* TLSv1.3 (IN), TLS handshake, Newsession Ticket (4):

< Date: Wed, 28 Oct 2020 21:45:38 GMT
< Content-Length: 19
< 
404 page not found
* Connection #0 to host user.example.io left intact

如果我启用注释行，HTTP 将 return“404 页面未找到”：

$ curl -v http://user.example.io
*   Trying 159.203.52.215:80...
* TCP_NODELAY set
* Connected to user.example.io (159.203.52.215) port 80 (#0)
> GET / HTTP/1.1
> Host: user.example.io
> User-Agent: curl/7.68.0
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 404 Not Found
< Content-Type: text/plain; charset=utf-8
< X-Content-Type-Options: nosniff
< Date: Wed, 28 Oct 2020 21:49:07 GMT
< Content-Length: 19
< 
404 page not found
* Connection #0 to host user.example.io left intact

我猜应该是设置出了点小问题，谁能找出问题所在？

Answer 1

从 traefik/v2.2/routing/routers/tls 的文档中，它说“当指定 TLS 部分时，它指示 Traefik 当前路由器仅专用于 HTTPS 请求（并且路由器应忽略 HTTP（非 TLS ) 请求).".

这解释了我遇到的所有情况。

我的解决方案是创建两个入口路由器，一个用于 HTTP，另一个用于 HTTPS。

Answer 2

我必须全局激活重定向。这可以通过取消注释来完成

redirectTo: websecure

在我的 Traefik 的 values.yaml Helmchart 中。所以你需要查看你的 Traefik 配置，以便检查这个。
