但是服务器正在容器内运行
docker exec 697bf01cf064 curl http://0.0.0.0:4200/
<!doctype html>
...
此命令
docker-machine ip default
返回
192.168.99.100
http://192.168.99.100:4200也不起作用
docker ps

答案 0 :(得分：2)
调试：
您无法在${host_ip}:4200浏览应用程序，这意味着该端口可能无法正常显示。
但docker ps部分下PORTS的输出有......
0.0.0.0:4200->4200/tcp
...这意味着端口已正确曝光。
让我们检查容器的IP上的端口是否可以访问（以消除对防火墙的任何怀疑）
docker inspect ${container_id}的输出显示您的容器IP为172.19.0.2（并且还证明端口绑定正确）。但http://172.19.0.2:4200也无法访问。
但是您已经提到机器内的curl 0.0.0.0工作，但在此上下文中，0.0.0.0表示“本地计算机上的所有IP地址”（实际上可能是“本地计算机上的所有IPv4地址”） ），其中还包括127.0.0.1又名localhost，但不能证明您的应用正在监听所有界面。
现在你说你用--host=0.0.0.0启动了应用程序，但我认为你仍然可以在应用程序代码中覆盖它。
因此，最好的情况是检查应用服务器的启动方式。
