Ingress HTTPS 代理訪問

創建證書，以及 cert 存儲方式

<code>openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=nginxsvc/O=nginxsvc"
kubectl create secret tls tls-secret --key tls.key --cert tls.crt

kubectl create secret generic basic-auth --from-file=auth

Nginx 進行重寫

名稱描述值nginx.ingress.kubernetes.io/rewrite-target必須重定向流量的目標URI串nginx.ingress.kubernetes.io/ssl-redirect指示位置部分是否僅可訪問SSL（當Ingress包含證書時默認為True）布爾nginx.ingress.kubernetes.io/force-ssl-redirect即使Ingress未啟用TLS，也強制重定向到HTTPS布爾nginx.ingress.kubernetes.io/app-root定義Controller必須重定向的應用程序根，如果它在'/'上下文中串nginx.ingress.kubernetes.io/use-regex指示Ingress上定義的路徑是否使用正則表達式布爾

<code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-test
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: http://foo.bar.com:31795/hostname.html
