Puppet users - Dec 2011 - how to restrict an exec?

Hi,
  Is there some way to have an exec run only if you pass a tag on the command
line?  For example:


class fubar {
  exec { ''reboot-system'': 
    refreshonly => true,
    command => ''/usr/bin/reboot'',
    subscribe => Class["dummy"]
  }
}


As I would expect, this throws an error the it can''t find the dummy
class.  Any suggestions on how I could accomplish this?

You can use facter to conditionally do this. Basically any environment
variable starting with FACTER_ will become a puppet fact.

FACTER_reboot=true puppet agent -t
class fubar {
if $reboot {
  exec {
  ...
  }
}
}

Thanks,

Nan

But that wouldn''t work with puppet kick, right?  I want to be able to
have a host reboot another host.  :-)

That looks to me more like an orchestration issue, which is probably better
solved by a tool like mcollective, func, rundeck, ...
You are not changing state here, merely executing a "procedure".

Kind regards,
