【问题描述】：
我有使用 Dockerfile 设置的 Rail-Api 服务器，我试图从主机访问它，但在启动 rails 服务器并卷曲 Docker 容器后连接被拒绝。
卷曲
curl 192.168.99.100:32776
Docker 容器：端口
iptables -L on 'docker-machine ssh default'

【问题讨论】：
-
你是如何启动你的容器的？另外，您如何从主机配置
entry端口？ -
我尝试过使用命令行`docker run -it -p ....`以及仅使用kitematic 来配置和运行容器。 @Rico
-
你在 Mac 上运行 curl？
-
@Rico 是的，我在虚拟机内部也试过了
-
你用什么完整的 docker 命令来启动应用程序？或者您使用什么命令来启动 Rails 服务器？另外，你可以 ssh 到容器吗？
