Sorry if this has been asked, but Google has failed me and I haven''t
been
able to find an answer.
With a source one can declare array so that if file exist puppet will pull
it out first, if not move to the next file in this fashion:
source => ["puppet:///conf/httpd_$hostname.conf",
"puppet:///conf/httpd.conf",
],
To the best of my knowledge one can''t do that with a Template (at
least as of 0.24, I am hoping this has changed).
What is the recommended way of dealing with this?
I do know that I can have an "if" statement within a class/module to
go like this:
if $hostname {
content =...
However that isn''t as clean as being able to do this from within the
same array as "source". That way instead of keep having to add
"if/else" I can simply add a file as needed.
Thank you!

Hey Marek, Templates do have different functionality here - they will concatenate arrays of templates (i.e. if you pass more than one template, it concatenates them all together into one file). You might want to check out the blog on separating data from code ( http://puppetlabs.com/blog/the-problem-with-separating-data-from-puppet-code/) to see ways that you can specify that piece of data entirely separate from your puppet code.

Hello Thank you Unfortunately this won''t help me at the moment because the files are different completely and not just few parameters. I need different templates based on hostname. I am fully aware that I can use "if" but well..ahm.. its ugly :) On Thu, Apr 12, 2012 at 10:53 AM, Gary Larizza <gary@puppetlabs.com> wrote:> Hey Marek, > > Templates do have different functionality here - they will concatenate > arrays of templates (i.e. if you pass more than one template, it > concatenates them all together into one file).

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.

Marek,
I''d suggest using something like the following to use a template based
on hostname:
file { ''/path/to/file'':
template => $hostname ? {
/regex/ => ''puppet://module/template.erb'',
/regex2/ => ''puppet://module/template1.erb'',
default => ''puppet://module/default-template.erb'',
}
}
This is a more elegant solution than a bunch of if statements, well this
is essentially an if statement as well, just prettier.
