Dear all,
I''m trying to figure out how to do this - first copy a
"common" file to
every node and then modify the file according to the node type. I''ve
tried
this:
if $node_type == ''wn'' {> $port = ''8649''
> $desc = ''Worker Nodes''
> }
>
> exec {
> ''n_desc'':
> command => "sed -ic ''/cluster {/,/}/s/name =
\"[^\"]*\"/name =
> \"\''\"$desc\"\''\"/''
''$fname''",
> subscribe => File["$fname"],
> refreshonly => false;
>
> ''n_port'':
> command => "sed -ic ''/port\ =\
/{s:[0-9]*$:$port:g}'' ''$fname''",
> subscribe => File["$fname"],
> refreshonly => false;
> }
>
> file {
> ''gmond.conf'':
> name => "$fname",
> source =>
''puppet:///modules/ganglia/gmond.conf'',
> require =>
Exec[''n_desc'',''n_port''],
> notify => Service[''gmond''];
> }
>
The problem is the *Exec[''n_desc'',''n_port'']
*is being executed but then it
changing back to the original one as supplied by: *source =>
''puppet:///modules/ganglia/gmond.conf''*, which is definitely
not what I
want. How can I make sure it copy the file first and then make the changes?
Or, simply how do I do that? Cheers!!

Hi, I think templates would be easier to manage in this setup. http://docs.puppetlabs.com/learning/templates.html It will give good flexibility. It the way I have managed my ganglia setup.

Yes, I did think about using template one point. So, do you generate the entire file using "template"? For us, it''s just a few lines to change in the default gmod.conf file. cheers, San On Tuesday, May 22, 2012 9:02:59 AM UTC+1, denmat wrote:> > Hi, > > I think templates would be easier to manage in this setup. > > http://docs.puppetlabs.com/learning/templates.html > > It will give good flexibility.

Yep. Templates are just normal files that go through the ERB parser so you can make adjustments on the fly. And it appears you are trying to push out the file anyway (using the source => param) so it seems like a good fit to me.

Use a template instead. Then you can install the file already modified for the host.

Thanks Den, Jo! I did it using template() now. Cheers, San On Tuesday, May 22, 2012 11:10:39 AM UTC+1, Jo wrote:> > Use a template instead.
