[SOLVED] docker-ce not showing up in `yum list available` with repo installed

Issue

Edit: I'd still like an answer to this question if possible, but I have managed to work around it by directly installing the individual rpms rather than relying on yum to do it for me.

I'm struggling with installing docker-ce on a CentOS 7 box. I have it installed on three other boxes, but the fourth is giving me problems. I am following the instructions here. Installing the repo appears to work, but docker-ce doesn't appear to be available no matter what I try.

Error: Nothing to do

The repo is obviously enabled. I am able to install containerd.io from the repo. It just appears that nothing else is available in the repo. Even when I copy the repo from another CentOS7 box where it works, I still don't see the docker-ce package. This repo worked fine on three other boxes tonight.

Any help would be appreciated. Thanks in advance!

Edit:

Running yum clean all and yum update have not helped.

Solution

There are many ways of enforcing yum to exclude a repo. One of them is by setting the exclude directive on /etc/yum.conf. This config has priority over the --disablerepo and --enablerepo flags.

You must check your /etc/yum.conf, removing the exclude or forcing yum to ignore it using the --disableexcludes=all flag.

--disableexcludes=[all|main|repoid]
Disable  the excludes defined in your config files. Takes one of three options:

all == disable all excludes
main == disable excludes defined in [main] in yum.conf
repoid == disable excludes defined for that repo

e.g:

yum --disablerepo="*" --enablerepo="docker-ce-stable" --disableexcludes=all list available
