Question

我在新的专用服务器上安装了docker（在通用的ubuntu 14.0 - linux内核3.13.0-71上）。我安装了一个ubuntu docker镜像来测试环境。（docker run -it ubuntu bash）我用openssl支持安装了curl。

当我尝试获取HTTP页面的内容时，我没有问题。当我尝试加载HTTPS页面时，我的连接被拒绝：

root@835f01fef568:/# curl https://www.google.com
curl: (7) Failed to connect to www.google.com port 443: Connection refused

在详细模式中我有：

root@835f01fef568:/# curl -V https://www.google.com
curl 7.35.0 (x86_64-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smtp smtps telnet tftp 
Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP

如果我尝试在文件中记录跟踪，我有：

== Info: Rebuilt URL to: https://www.google.com/
== Info: Hostname was NOT found in DNS cache
== Info:   Trying 173.194.123.81...

我对自己可以做的事情有点失落:( 这不是DNS问题，因为我可以ping端口80上的服务器或CURL http内容。它只与SSL连接有关。这里有人对这个问题有任何想法吗？

由于

Answer 1

我找到了问题的根源。这与主要主机的iptables问题有关

使用命令iptables -L -t nat我发现在重定向到端口9092的所有https流量上都激活了预路由，由另一个服务使用。

Answer 2

我有同样的问题。我发现将iptables规则的界面设置为“ eth0”而不是“ any”可以解决问题。

以下是为我在主机上工作的示例：

iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 443 -j DNAT --to-destination 172.17.0.3:8443

接口更改为“ eth0”后， wget https：// ... 从docker内部重新工作。

希望这会有所帮助。

Answer 3

echo ipv4 >> ~/.curlrc

在终端上运行此命令。它对我有用

无法从docker镜像连接到HTTPS（443）
