问题:
ubuntu服务器A上，docker容器内 curl https://www.ygdy8.com问题
问题：
root@qyi-58abe6739f7ae:~# curl https://www.ygdy8.com //1.宿主机下正常访问
<meta http-equiv="refresh" content="1;URL=index.html">
root@qyi-58abe6739f7ae:~# docker exec -it 1e398e2637b5 bash
root@1e398e2637b5:/app# curl https://www.ygdy8.com //2.容器内报证书签名问题
curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

root@1e398e2637b5:/app# curl https://www.baidu.com //3.容器内访问其它https站点正常
<!DOCTYPE html><!--STATUS OK--><html>...</html>

期望：
期望容器内 curl https://www.ygdy8.com得到跟宿主机相同的结果
自己尝试过的问题排查：
1，下载证书并指定证书访问，结果提示证书过期。
root@1e398e2637b5:/etc/ssl/certs# openssl s_client -showcerts -servername server -connect www.ygdy8.com:443 > ygdy8.pem depth=0 C = US, ST = California, O = Super Micro Computer, OU = Software, CN = IPMI verify error:num=18:self signed certificate verify return:1 depth=0 C = US, ST = California, O = Super Micro Computer, OU = Software, CN = IPMI verify error:num=10:certificate has expired notAfter=Dec 19 00:00:00 2016 GMT verify return:1 depth=0 C = US, ST = California, O = Super Micro Computer, OU = Software, CN = IPMI notAfter=Dec 19 00:00:00 2016 GMT verify return:1 quit root@1e398e2637b5:/etc/ssl/certs# curl --cacert ygdy8.pem https://www.ygdy8.com curl: (60) SSL certificate problem: certificate has expired More details here: https://curl.haxx.se/docs/sslcerts.html
2，通信过程，发现宿主机和容器内解析的IP不一致，然后我修改了容器内host，把该域名解析IP指定成了宿主机解析的IP，得到的结果跟上面一样certificate has expired

3，我在另一台ubuntu服务器B下，pull了同样的镜像，然后启动容器，进入容器内curl却没有任何问题，我怀疑是服务器A的问题，或者说是服务器A的docker网络配置问题。两台机器docker是同样的安装方式，并没有设置过网络相关配置。
回答1:
可能是因为 openssl 版本或者配置问题
容器内
* TLSv1.2 (OUT), TLS header, Certificate Status (22):宿主机内
* TLSv1.3 (OUT), TLS handshake, Client hello (1):回答2:
对比一下你的服务器A和服务器B上的镜像的签名是否一致，是不是用了latest镜像？两个地方的不一致
