ingress-nginx

• 部署ingress-nginx 控制器

  kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.4/deploy/static/provider/cloud/deploy.yaml
  

• 測試tls

  openssl genrsa -out tls.key 2048
  openssl req -x509 -new -key tls.key -out tls.crt -subj /CN="*" -days 3650
  kubectl create secret tls https-test --cert=./tls.crt --key=./tls.key

• 在k8s 叢集外使用代理訪問

  upstream test {
  	 	server 10.4.7.50:31196;  # 10.4.7.50:31196  ingress controller的地址和埠
  		}
  
  	server {
          listen       80;
          location / {
          rewrite ^.*(.*) https://test.com:31196/$1 permanent;
          }
