ImportError: libGL.so.1 on CentOS

Question

When I try to import cv2 in python I get the following error:

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I found this thread which suggested I install libgl1-mesa-glx, but I'm wondering if that's only available on Ubuntu because I'm on CentOS and when I try to sudo yum install libgl1-mesa-glx I get No package libgl1-mesa-glx available. Also, when I added the installation to my dockerfile I got this error: The command '/bin/sh -c yum install libgl1-mesa-glx' returned a non-zero code: 1

Then I found what looked like a Fedora solution to the same problem that said to use mesa-libGL-devel. When I sudo yum install mesa-libGL-devel it appears to install correctly, but when I added that to my dockerfile I get The command '/bin/sh -c yum install mesa-libGL-devel' returned a non-zero code: 1.

What else should I try?

EDIT: Here is the Dockerfile:

Just add this command:

yum install mesa-libGL
