How to install vim in a docker image based on mysql version 8?-CodePudding

I had been using mysql version 5.7 and this was working.

Dockerfile (working)

FROM mysql:5.7

...

RUN yum update -y; yum install -y vim

Then I upgraded to mysql 8 and now I'm getting this error.

$ gnt build

...

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

CodePudding user response：

If you take a look at the Tag for 8.0 you can see that the base uses a different version of Oracle linux (8 vs 7). Yum is not installed in 8. Instead, there's a minimal installer (microdnf). So this substitution should work for you:

microdnf install -y vim
