k8s nginx-ingrss-controller無法解析https請求

問題：HTTPS轉發報錯failed to convert certificate chain from PEM to DER: PEM_read_bio_X509_AUX() failed
分析：谷歌搜索https://github.com/kubernetes/ingress-nginx/issues/4106分析是Nginx Ingress Controller版本問題，

	It can be fixed by upgrading the Nginx Ingress Controller to version 0.25.0 or higher. Alternatively, you can downgrade to version 0.23.0.

解決：無論升級還是降級都沒有解決問題，反而Nginx Ingress Controller無法啓動了。
但是在升級到version 0.25.0的過程中看到了日誌設置了個參數–enable-ssl-chain-completion=false，這個參數跟以上問題看着有點關係，所以決定改回v0.24.0版本，並添加以上參數。

"spec": {
        "containers": [
          {
            "name": "nginx-ingress-controller",
            "image": "quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.0",
            "args": [
              "/nginx-ingress-controller",
              "--enable-ssl-chain-completion=false",
              "--default-backend-service=kube-system/ningx-ingress-nginx-ingress-default-backend",
              "--election-id=ingress-controller-leader",
              "--ingress-class=nginx",
              "--configmap=kube-system/ningx-ingress-nginx-ingress-controller"
            ],

添加以上參數後問題結局。此問題解決可謂是一波三折，百度，谷歌都沒有解決，無意中發現這個參數，竟然解決了。
