Honestly, I’m not sure about docker, but my plan is just to install it and
see how it goes. Seems like Amazon Linux is closest to CentOS 7, so I’m
going to try that install process and see how it goes. Unless people here
think the RHEL install walkthrough might be better, but IIRC the two are
almost identical.
Either way I’m doing foreman and katello, so AFAIK this
https://theforeman.org/plugins/katello/3.5/installation/index.html is my
process (that is: install katello and then use foreman as a scenario) .
