kubernetes 入口控制器`400 錯誤請求 - 普通 HTTP 請求發送到 HTTPS 端口`

Question

我有一個 AWS NLB 入口控制器和一個入口規則，用於在 API 和 SPA 之間路由流量。 The ingress-controller works perfectly on HTTP, but on HTTPS I'm getting a 400 Bad request - plain HTTP request sent to HTTPS port

如果我理解正確，在 TLS 終止后，請求將通過 Https 端口而不是 HTTP 重定向，但我很難找到：

我確實在這些背后進行了部署，但是由於服務本身可以獨立運行並在 http 上協同工作，因此我已將它們排除在此問題之外。

任何意見是極大的贊賞！

Answer 1

我只是浪費了一整天的時間來解決這個問題，結果證明是 Helm 創建的服務中的端口配置。 https 配置中的 targetPort 需要為 80 而不是參考“https”。

前：

  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: http
    - name: https
      port: 443
      protocol: TCP
      targetPort: https

后：

  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: http
    - name: https
      port: 443
      protocol: TCP
      targetPort: 80

這是您的服務的外觀：

apiVersion: v1
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: http
    service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: '60'
    service.beta.kubernetes.io/aws-load-balancer-cross-zone-load-balancing-enabled: 'true'
    service.beta.kubernetes.io/aws-load-balancer-type: nlb
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "https"
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:us-east-2:XXX:certificate/XXXXX
