如何在基于mysql版本8的码头映像中安装vim？

Question

我一直在使用MySQLVersion5.7，这是可行的。

Dockerfile (工作)

FROM mysql:5.7

...

RUN yum update -y; yum install -y vim

然后我升级到mysql 8，现在我得到了这个错误。

$ gnt build

...

#5 [ 2/12] RUN yum update -y; yum install -y vim

Dockerfile (不工作)

如果您看一下8.0的标记，就会发现这个库使用了不同版本的Oracle linux (8比7)。Yum不是安装在8，而是有一个最小的安装程序(microdnf)。所以这个替代应该适用于你：

microdnf install -y vim
