I'm not sure to really understand what you try to do. But if the point is
to manage 1000 server from scratch you can :
Install you puppet server
Activate de autosign.conf for you domain.
Put inside you
manifests/site.pp
something like
node default {
hiera_inlcude('classes')
}
inside your hieradata/common.yaml
classes :
- my_roles:default_role
inside the file
modules/my_roles/manifests/default.role.pp
you can put
package { 'screen' : ensure => 'installed' }
To deploy puppet on your node, if you really have 1000 node, some good
point is to put the installation and configuration of puppet inside your
deploiement script (depend on what flavor of linux you use, but RedHat has
kickstart, Debian has fai etc..)
Or you can (even better) put everything inside you hieradata (list of
pacakge), in that way it's more easy to manage different OS, but I think if
you need 1000 nodes they are all the same so...
Regards.
