Using a fact in "onlyif"

[Mike Reed]

Hello all,

I've been stumped by this one and I was hoping for a little help.  I'd like the below snippet to run only if the operating system is a specific version.  Because facter already has the "operatingsystemrelease" variable, I figured I'd use that but haven't had any luck getting it actually work.  Does anybody know how I would add the "onlyif" in the below snippet using the "operatingsystemrelease" fact?

I also suspect this could be the wrong way to do this and any advice would be greatly appreciated.

file { "/var/lib/nfs/rpc_pipefs" :
                       ensure   => "link" ,
                       onlyif     => "${operatingsystemrelease}" == "10.04" ,
                       target    => "/run/rpc_pipefs" ,
                }

*note: this onlyif does not work...just added for clarity in terms of what I'm trying to achieve

Thanks in advance for the help.

Cheers,

Mike

Since this shells out you could do something like this


onlyif => "[ '${::operatingsystemrelease}' = '10.04' ]",


Thanks

'onlyif' is not a valid parameter for puppet 'file' type. Conditional logic is handled by one of puppet's conditional statements (http://docs.puppetlabs.com/puppet/latest/reference/lang_conditional.html).  In this case, wrapping your file resource in an 'if' statement will suffice, but I encourage you to read the linked document to see what else is possible.

if $::operatingsystemrelease == "10.04" {

    file { "/var/lib/nfs/rpc_pipefs" :
        ensure   => "link" ,

        target    => "/run/rpc_pipefs" ,
    }

}

Hah, I wasn't paying attention at all, I thought the resource was an exec.

Hey Eric,

Thanks very much for the reply and info.  I added that in and it now looks like:

file { "/var/lib/nfs/rpc_pipefs" :
                        ensure  => "link" ,

                        onlyif  => "['${::operatingsystemrelease}' = '12.04']" ,
                        target  => "/run/rpc_pipefs" ,
                }

Unfortunately, I'm getting this error:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter onlyif at /etc/puppet/modules/autofs/manifests/init.pp:17

I'm trying to do some reading about this now but just wanted to get this back because I very much appreciate the help.

Cheers,

Mike

Hey Peter,

Thank you for the info.  I'll read the attached link and get a better understanding of this one. 

As a note, the below if statement worked like a charm.

Thanks again for the help.

Cheers,

Mike
