问候，

我跟着搬运工撰写快速入门例如在https://docs.docker.com/compose/django/，使用CentOS的VM和Ubuntu VM我的搬运工环境。该示例在CentOS中运行，但不在Ubuntu中运行。故障发生在

错误是

你能帮我故障排除这一点，明白为什么这种情况发生在Ubuntu的，但不是在CentOS的？

谢谢...

Answer 1

运行点匹配搜索，并确保你在找什么。看起来像是它实际上找不到的错误。

Docker文档倾向于在主站点上过期。

原来，我的/etc/resolv.conf指向了一个错误的名称服务器。我仍然需要调查为什么发生。如果手动将正确的DNS，码头集装箱有网络。
