我们在我们公司使用自定义 yum 存储库。有些事情导致他们无法执行yum makecache命令。
我在CentOS Linux release 7.7.1908 (Core)。
这是我们运行时得到的错误yum makecache：
One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this
回购看起来像这样，我需要同时使用它们。
埃佩尔回购：

在创建容器指令docker run时,-dns也不会更改/etc/resolv.conf中的条目
如何永久更改/etc/resolv.conf中的条目？
