[Puppet Users] How to deal with a slightly changing file?
I have a file that is part of a software I am installing via puppet...
the file is constructed from a template, as it has a couple of fields
I wanna be able to change in the future.
The file is updated by the app itself, upon restart, which changes
just one field, in a key=val line...the result is that puppet rebuilds
the file, and becuase of depnedecy, restarts the app at each run.
Can I somehow say ignore that one line?
file { "splunk_outputs":
owner => splunk,
group => splunk,
mode => 644,
require => [Package["splunk"]],
path => "/opt/splunk/etc/system/local/outputs.conf",
content => template("gu_splunk/outputs.conf.erb"), #but
please
ignore line starting with: sslPassword notify =>
Exec["restart"],
}
Thanks a lot.
Mohamed.

Re: [Puppet Users] How to deal with a slightly changing file?
Not really. There are a couple ways to handle this: 1) Make use of includes. Have the puppet-managed file include the app-managed file. Of course, this requires the app to be friendly to this kind of setup. 2) Add "replace=>false" so that Puppet will create the file but never update it if it exists. Of course, that breaks when you have updates that you really do need puppet to apply. 3) Install/use augeas. You''ll probably need to write an appropriate lens, but if done correctly, this is very robust. 4) Use an exec to modify the file in-place. This is fugly. 5) Use an exec with the application''s CLI to to have the application make the updates. Better than 4, but still not exactly beautiful.

Re: [Puppet Users] How to deal with a slightly changing file?
Thanks Brian... Looks like 2 and 3 are my options.... 2) Add "replace=>false" so that Puppet will create the file but never update it if it exists. Of course, that breaks when you have updates that you really do need puppet to apply. When I need to force the update, I would simply comment out the ''replace" for one run? is there a better way?

Re: [Puppet Users] How to deal with a slightly changing file?
Either comment it out for the one run or delete the target file manually. Neither solution is really good.
