linux - dockerfile中的yum-没有启用的存储库

Question

我在dockerfile中使用yum安装python3时遇到问题。我确实在互联网上看过，但是我尝试了一些尝试，但是没有用。它只是一件小事，但无法弄清楚。当我尝试在docker文件下构建时，出现错误。我在行上遇到错误-

运行yum install -y oracle-epel-release-el7

There are no enabled repos.
 Run "yum repolist all" to see the repos you have.
 You can enable repos with yum-config-manager --enable <repo>

docker文件在下面。

为什么要混合apt和yum？您已经在使用apt-get，也可以使用它来安装python:

apt-get install python3.6
