I am looking to find out what is the recommended way to setup a new environment, where each component of the foreman stack is responsible for a particular task. Right now, I have foreman and Puppet master in the same server. I am trying to gauge whether it makes sense to separate the foreman and Puppet master and Katello into their own separate hosts. The individual parts are:
Foreman: For provisioning
Puppet master: Configuration management/External node classifier/Puppet dashboard
Katello: Content host management
Right now, I provision hosts using foreman and assignt he classes to the new host using ‘Puppet classes’ tab so that the new host obtains all necessary configuration. Therefore, I have to maintain an ‘always-on’ line between the foreman and Puppet master, if I decide to put those two responsibilities in two separate hosts.
The environment will be located in vmware and not on any public/private cloud. Although requirements of that nature may come in future, but I haven’t heard anything like that so far.
Given above information, what is the suggested/recommended way of setting up the new environment will be? I have to support a mix of RHEL6 and RHEL7 hosts, although the new foreman environment will be in RHEL7.
Any questions/comments are highly appreciated.
