Make sure folder is fully copied

[Stelian Iancu]

Hi all,

I am new to Puppet and I'm trying to accomplish a fairly simple task. I need to deploy a folder to the server and, once it's copied, I need to run a shell script in that folder.

Basically I have something like this:

file { "/home/user/res":

                  ensure => "directory",

                  owner  => "user",

                  group  => "user",

                  recurse => "true",

                  ignore  => ["logs", "downloads"],

                  purge  => "true",

                  mode   => "0750",

                  source => "puppet:///files/res/",

          }

         exec { "start_res":

                 command => "/home/user/res/run.sh"

         }

         File['/home/user/res'] -> Exec['start_res']

The problem is that the deploymnet of the res folder is not treated atomically. So once a few of the files have been copied, puppet tries to execute the run.sh script which is not there at that moment.

Is there any way I can make sure that run.sh is executed only after the deployment of the folder has finished?

Thanks!

The best way I've found to handle folders that contain items puppet later needs to act on is to use fpm to turn them into an rpm/deb and add them to a repo. This way you're not using puppet as a file server -- something you should avoid wherever possible. Puppet can use a package resource to install the entire folder, and then notify an exec resource that runs the script.

If you'd rather not have the package in a repo, you can put the package in place using a file resource and have the package resource require the file resource.
