如何在基于mysql版本8的docker镜像中安装vim ?

Question

我一直在使用mysql 5.7版本，这是工作

Dockerfile(工作)

FROM mysql:5.7
...
RUN yum update -y; yum install -y vim

然后我升级到mysql 8，现在我得到这个错误。

$ gnt build
...
#5 [ 2/12] RUN yum update -y; yum install -y vim
#5 sha256:a564337cc7df72796c4c967652d420ef76ec98034de106834a473bceb4889532

Dockerfile(不工作)

FROM mysql:8
...
RUN yum update -y; yum install -y vim

如果你看一下8.0的标签，你会发现基础使用的是不同版本的Oracle linux (8 vs 7)。取而代之的是一个最小的安装程序(microdnf)。所以这个替换应该对你有用:

microdnf install -y vim
