Is ther any update on this?
We’re starting to roll out our initial CentOS8 machines and this is the last thing that’s missing right now 
There is work that we have to perform to update our build system to handle CentOS 8. Given this, we are planning to package client bits for the 1.25 release (and available in nightly sometime before that) which will put this available within the next 3 months.

any update on this yet?
For Foreman 2.0 there are initial EL8 client bits at https://yum.theforeman.org/client/2.0/el8/x86_64/ but katello-agent itself is not there yet due to an issue with the gofer dependency. Also note that 2.0 is currently at RC1. This is being worked on.

When can we expect release of Foreman 2.0?
In Katello 4.0 the katello-agent will no longer be supported. Due to the migration to Pulp3 it will no longer work. We’re officially deprecating the agent in Katello 3.16 so there will be time for folks to adapt. We are recommending looking at the Remote Execution plugin to continue pushing updates to content hosts.
Since we’re dropping agent support in ~2 releases, there’s no plan to provide katello-agent packages for EL8.

Jonathon. So this means that instead of using the katello agent for subscription management, we will need to use the remote execution and write some scripts to manage the client yum repos setup?
I expect that this would be handled via a job template.
I’m using satellite (RedHat rebadge katello etc) and RedHat have a repo that allows some form of katello-agent for RHEL8 (satellite-tools-6.5-for-rhel-8-x86_64-rpms). I can’t seem to make this available to CentOS 8 machines (not sure if that’d be a good idea anyway); I’m assuming because of licensing. If anyone has a way of sorting that, I’d be so happy.
In the meantime it looks like we will be using the job templates for centos8 and katello-agent ofr centos7, rhel7, and rhel8.
This is correct. If you are missing functionality, it would be great to hear.
This will likely work if you take the SRPMs and rebuild them, though I recall that there was Python 2 involved and that made things significantly harder. For what it’s worth, Satellite will follow upstream and deprecate katello-agent as well (which shouldn’t surprise anyone).
I wonder if this means that Redhat will also soon be dropping the whole subscription agent idea for Satellite for remote subscription management on RHEL as well. If not, then there should be source code for their stuff.
Edit: Oh, that is what ekohl just said above.
Yeah, manual attempts to install packages and hunt down dependencies end up at this point:
- nothing provides /usr/bin/python needed by katello-host-tools-3.3.5-4.el7.noarch
Trying to install an older version of katello-agent as a work around failed because it would need python reverted to an older version which is not a possibility.
I’m trying to hunt down how job updates might work. It might almost be easier to tell the clients to run updates themselves e.g. through a cron job.
FWIW, I think installing anything from the satellite-tools repository on a non-RHEL machine will be in breach with your RH contact, please read it to be sure. 
That said the 2.0 client repository contains EL8 bits (as already mentioned), including katello-host-tools but without katello-agent, as that won’t be supported on EL8 on Katello (as Jonathon wrote).
The 2.0 client bits should work for Foreman 1.22 (Katello 3.12) and later.
The only missing feature you should see is the “push” of package installs/updates from Katello to the clients using the agent. Subscription, reporting etc all work just fine without the agent. For package install/update, we recommend to use Remote Execution which Katello already provides job templates for.
There’s a lot of confusion in this thread.
Subscription-manager is for management of assigned subscrpitions
Katello-agent for remote installation/updating of packages and errata triggered from a katello server
katello-agent is deprecated and being removed in an upcoming release. Subscription-manager is not.

So, I I’m on Katello 3.7.1.1 (Foreman 1.18.2).
I don’t understand what should I do to manage RHEL8/CENTOS8 servers.
Can someone kindly explain it to me?
I imagine I have to update my Katello server, and it’s not a problem, and then ?
Thanks
Katello 3.10 added support for EL8 so that’s the minimum version you want to be on. I’d strongly recommend the latest supported version.
Thank you for your answer.
So, is there a katello-agent for RHEL8 or have I to make something on my own to replace it?
Bye
Our client tools only started to support EL8 with 2.0 which just went GA yesterday.
There will not be a katello-agent for EL8. With dropping Pulp 2, and Pulp 3 no longer supporting this model the project is dropping this functionality and encouraging users to use (Remote Execution)[Foreman :: Plugin Manuals] which features an SSH based ability to execute operations on your hosts. There is also an Ansible plugin for using Ansible based remote execution.
