My organization is putting together a beaker cluster for testing on ever advancing hardware. We are concerned about launching the cluster on RHEL/CentOS 7 because they are no longer supported, which may result in challenges in testing new hardware. I am evaluating building the cluster on CentOS8, but, beaker-server fails with the following during installation:

Error:
Problem: cannot install the best candidate for the job
  - nothing provides python-netaddr needed by beaker-server-27.4-1.el7bkr.noarch
  - nothing provides python-lxml needed by beaker-server-27.4-1.el7bkr.noarch

  - nothing provides python-requests >= 1.0 needed by beaker-server-27.4-1.el7bkr.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I suspect it's because beaker uses OS ver 7 with python2 and RHEL/CentOS8 installs python3. I installed python2 and tried adding the missing python packages, running update, flushing cache, etc, and it still fails with the same. 

I can easily build the server on CentOS7. It's flawless to get the daemon running. But, we are concerned about the maintenance OS and emerging hardware. Is there a way to get server to run on OS 8, and will it be ported to 8 and python3 in the near future?
