未将版本指定为image: mysql时，它将使用最新版本。此时，提出的问题是8.0.16，请参阅this。

当您将版本指定为image: mysql:8.0.0时，您仅使用旧版本的mysql。

不幸的是，此版本与下一个新的docker不兼容：

服务器将mbind用于NUMA（非统一内存访问）操作，但是Docker默认情况下会阻止此访问。可以提供一个允许它的自定义配置文件，但是配置文件的语法在Docker版本之间有所变化，因此有点混乱。

这意味着，该映像在较早的时候可以工作，但是现在docker升级了，mysql映像应该进行相应的更改。而且，8.0.16（当前是最新的）已经进行了此修复，因此可以。详细信息请参见下一个讨论：
