Install does not work on CentOS 7

I deployed a centOS7 VM this weekend and followed the install instructions. Running the install script failed. The only Docker it started was the homeassistant/amd64-hassio-supervisor and it was not connected to the servers ports.

I fiddled with it for a few hours and never did get it working.

I did deploy an ubuntu server and get it working however I would have prefered to have a CentOS system as ubuntu is a one off in my network.
