Right,
If you used something like Hiera you could do a lookup on a variable (like
$foo_content for example) and hiera would pass a different value for the
content attribute based on the hostname of the machine. So if it were one
hostname you could get something like
"template('module/first_template.erb')" and another hostname would return a
value of "template('module/second_template.erb')". Then, in the
declaration, you could do:
file { '/path/to/file':
ensure => present,
content => $foo_content,
}
Your Puppet code would be generic (only using a variable) and all your data
would be determined in Hiera. If you're interested in this method, there's
also a blog post for using Hiera here -->
