[Puppet Users] Defining node types in modules

Hello,

This is the way we currently define nodes using modules/classes. Unsure if
this is the best method but as dashboard does not do parameterized class
variables seems the right way.

We apparent zen_ to everything thats making up our servers. I am having
problems with the MySQL module as I need to include mysql:: several times
to get the features - https://github.com/puppetlabs/puppetlabs-mysql

err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Duplicate declaration: Class[Mysql] is already declared; cannot redeclare
at
/etc/puppet/modules/zen_puppet01opslab/manifests/puppetdashboard_mysql.pp:2

I question if we are using the right approach with puppet and if this is
the right way to define types of servers.

Module: - zen_puppet01opslab

}
