Puppet users - Dec 2010 - if then statement within file resource

Hello All,

     I''m not able to do an if/then statement within a file resource 
declaration.  I''m basically trying to distinguish between OS release,
so
that I can assign an appropriate template.  This is what I have:

class basic_dev::files {
        file { "/etc/sudoers":
        owner => root,
        group => root,
        mode => 0440,
        if $operatingsystemrelease <= 5.4 then {
        content => template("system/sudoers_V54.erb")},
        else {
        content => template("system/sudoers.erb")},
       backup => ".bak"
       }
For some reason is not working.  I keep on getting error: "Could not 
retrieve catalog from remote server: Error 400 on SERVER: Syntax error at 
''if''; expected ''}'' "

Any ideas?

Thanks,

What about just doing:

if ($operatingsystemrelease <= 5.4) {
	$sudo_template = "system/sudoers_V54.erb"
} else {
	$sudo_template = "system/sudoers.erb"
}

class basic_dev::files {
        file { "/etc/sudoers":
        owner => root,
        group => root,
        mode => 0440,
        content => template($sudo_template),
        backup => ".bak"
       }

Seems legit at least ;)

You can do it magically with source, not sure about template though.
 source =>
["puppet:///system/sudoers_$operatingsysstemrelease","puppet:///system/sudoers"]
(it will look for them in order. We have several that go hostname,
$lsbdistcodename, generic.)

If it doesn''t work for template, you can do it the hard way:

  if $operatingsystemrelease <= 5.4 {
    file { "/etc/sudoers":....etc
  } else {
    file { "/etc/sudoers":.....
  }

Yes the language tutorial on conditionals explains this.  You can use a selector
inside the resource or the if/else syntax outside the resource to set a
variable. Selector is less nice because you can''t do the numeric
comparison, you have to fake it with a regexp.

ie.

file {"/etc/sudoers":
 content => $operatingsystemrelease ?
 /^5.[01234]/ => template("system/sudoers_V54.erb"),
 default => template("system/sudeors.erb")
 }

or as other people described, move your if/else outside the resource to set a
local variable that you then expand.

That worked out.... Wondering why it didn''t inside the file resource...
but
it the workaround is certainly is "legit" enough....

Thanks,

Hi,

I believe in that case you should use selectors to make it work.

http://docs.puppetlabs.com/puppet/2.7/reference/lang_conditional.html#selectors

Or you can use the ''if'' outside the file resource.  Something
like this:

$template_name = $manufacter ? {
  ''ibm'' => "${module_name}/ibm.inittab.erb",
  default => "${module_name}/sun.inittab.erb",
}

Then your file resource
file { "/etc/inittab":
        owner => root,
        group => root,
        mode => 0644,
        content => template($template_name),
       backup => ".bak",
}

It''s also best practice to use selectors outside resource block per
http://puppet-lint.com/checks/selector_inside_resource/

I hope it helps.
