Question

我正在尝试使用Docker运行一些NightWatch测试，但似乎在CentOS上给我一个错误。当我在MacOS上尝试时，它会起作用。

我尝试更改端口，但这似乎不是问题。

终端错误

POST http://172.17.0.1:4445 /wd/hub/session - EHOSTUNREACH
Error: connect EHOSTUNREACH 172.17.0.1:4445
   An error occurred while retrieving a new session: "connect EHOSTUNREACH 172.17.0.1:4445"

Docker网络检查桥（在CentOS和MacOS中同样显示）

Docker容器

0.0.0.0:4445->4444/tcp   selenium-firefox

我希望它可以连接到selenium-firefox容器并运行测试。

如何修复Docker中的'EHOSTUNREACH'错误？
