The combined use of Ubuntu and CentOS

[Nevzat erçolak]

Hi, I am using puppetmaster on centos 6.5. I want to use puppet agent which is installed on ubuntu 12.04. I want to install and configure some package on ubuntu 12.04 via using puppet. Is it possible to use different operating system between puppetmaster and agents? If it is possible, how can I use and configure master and agent? Does anyone know how to use them both together?

Yep, totally possible. The puppet master daemon is platform-agnostic and uses the information sent from the agent (via `facter`) to know how to compile the catalog. So if your ubuntu agents check in, the master daemon makes ubuntu catalogs. If your centos agents (including the master managing itself) checks in, then it will have different facts and thus a different catalog.

Modules are commonly written to handle the different package & service names across platforms as well as different kinds of configuration defaults (eg, https://github.com/puppetlabs/puppetlabs-ntp/blob/master/manifests/params.pp#L42-L78) and can be run from any master (even AIX masters serving windows agents if a module is written to support windows :P).

AND, the agent adapts to the tools provided by its host OS.

Yes and no.  Most of the automation in this regard is in the agent, as a 'provider' appropriate to the host OS is automatically chosen for each resource type represented in its catalog.  There are OS-specific details not covered by facts that nevertheless need to be addressed in the manifests and/or data from which the master compiles catalogs -- package names, for example.

Exactly.  So, yes, you can totally service Ubuntu, and OS X, and even Windows clients with a CentOS master -- and plenty of people do.  But it's not magic.  Puppet does as much as it can to ease the way, but you still need to be mindful of the details yourself.
