A host is any virtual or physical Linux client that Red Hat Satellite manages. You have different ways to register a content host in Red Hat Satellite; either using the activation keys or using the interactive method by selecting the library.
You need to create an activation key which will be used later to register the content host. Remember to select the Library and Content View.
Goto Content -> Activation Keys -> New
Once the Activation Key is created, you will see the details including the command to register a client or Content Host.
On the RHEL8 host, check subscription status.
[[email protected] ~]# subscription-manager status

Make sure RHEL8 host is able to reach the Satellite server using FQDN (Fully Qualified Domain Name). If you do not have DNS in the environment, make sure you added the Satellite host entry in /etc/hosts
file.
[[email protected] ~]# ping -c3 satvm.lab.local
Now you need to install the katello-ca-consumer-latest.noarch.rpm
on Content Host (download from Satellite server)
[email protected] ~]# rpm -Uvh http://satvm.lab.local/pub/katello-ca-consumer-latest.noarch.rpm

Now you can register the Content Host using the activation key as below.
[[email protected] ~]# subscription-manager register --org="DEMO-ORG" --activationkey="RHEL8-Key"
The system has been registered with ID: cfe827c5-5839-425d-a2be-cbe7b1f61db5
The registered system name is: rhel8.localdomain
If you do not wish to use Activation keys, then you can directly register content host using username and password. But remember to select the Content view and Libraries manually.
[[email protected] ~]# subscription-manager register
