1.配了一个证书，发现报错：

kubectl logs ingress-nginx-controller-96fnv -n ingress-nginx

unexpected error validating SSL certificate gscommon/https-secret for host oa2https01.mz.abc.com. Reason: x509: certificate is valid for *.idcsec.com, not oa2https01.mz.abc.com

基本可以确定是证书有问题

2.参考思路：

2.1生成证书文件：

openssl req -x509 -nodes -days 2920 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=*.idcsec.com/O=nginxsvc"

2.2 导入证书文件到k8s secret

kubectl create secret tls https-secret --key tls.key --cert tls.crt

我的配置：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
ingress.kubernetes.io/ssl-redirect: "True"
kubectl.kubernetes.io/last-applied-configuration: |
