如何使用 Traefik 和 Kubernetes 創建到正在偵聽 Https 的服務的 HTTPS 路由

Question

我是 kubernetes 和 Traefik 的新手。

我跟進該教程： https://docs.traefik.io/user-guides/crd-acme/

我將其更改為在 Scala 中使用我的服務，它位於 https 和 9463 端口下。 我正在嘗試使用 kubernetes 和 traefik 部署我的 Scala 服務。

當我直接轉發到服務時：

kubectl port-forward service/core-service 8001:9463

我執行curl -k 'https://localhost:8001/health' ：

我收到"{Message:Ok}"

但是當我執行端口轉發到 traefik

kubectl port-forward service/traefik 9463:9463 -n default

並執行curl -k 'https://ejemplo.com:9463/tls/health'我得到一個"Internal server error"

我想問題是我的“核心服務”正在監聽 HTTPS 協議，這就是我添加的scheme:https 。 我試圖通過文檔找到解決方案，但它令人困惑。

這些是我的 yml 文件：

服務.yaml

apiVersion: v1  
kind: Service  
metadata:  
  name: traefik

spec:  
  ports:
    - protocol: TCP

    - protocol: TCP
      name: websecure
      port: 9463
  selector:
    app: traefik

從文檔

默認情況下，TLS 路由器將終止 TLS 連接。 但是，可以指定 passthrough 選項來設置請求是否應“按原樣”轉發，保持所有數據加密。

在您的情況下，需要啟用 SSL 直通，因為 pod 需要 HTTPS 流量。

apiVersion: traefik.containo.us/v1alpha1  
kind: IngressRoute  
metadata:  
  name: ingressroutetls
  namespace: default
spec:  
  entryPoints:
    - websecure
  routes:
  - match: Host(`ejemplo.com`) && PathPrefix(`/tls`)
    kind: Rule
    services:
    - name: core-service
      port: 9463
      scheme: https
  tls:
    certResolver: default
    passthrough: true
