Puppet Testing if a file exist

puppet

Solution 1

The "native" way to do this without execs if you're on Puppet 2.6.6+:

file { '/path/to/myfile':
  ensure => 'present',
  audit  => 'all',
}

(This functionality exists since Puppet 2.6.0, but there were a number of issues with auditing that only really got hammered out with the 2.6.6 release.)

If you're on an older version, you can also tell the resource to run in noop mode, which will just display a message when Puppet is run and the file doesn't exist:

file { '/path/to/myfile':
  ensure => 'present',
  noop   => 'true',
}

Solution 2

You should create yours own function or use exec with onlyif command. something like :

exec { "mycommand":
  path => "/usr/bin:/usr/sbin:/bin",
  onlyif => "test -f /etc/blalba" //yours command 
}

Im looking for a way to test if a file exist in my client (just test not creation). I've found the way (File.exists) in chef but that wasn't simple with puppet.

Thanks in advance.

ensure => present will create the file if its not existing. bazic only wants to test and not create it. See docs: docs.puppetlabs.com/references/stable/type.html#file

@MealstroM: Wouldn't "creates => '/etc/blabla'" be better than an "onlyif"?

@freiheit creates =>... is something different. it means that exec command should create file in creates => and if there is no this file than the command runs. and if you just want to check some /run/pid this command isnt good. and with onlyif you can check empty or not the file is :D

yeah. this is great with new version ov puppet. ive been working with pre 2.6.0 and have to write my own ruby function for file exist/empty check.

@MealstroM: In this particular case, creates would have the same result and be much simpler (and a bit faster). Yes, in general onlyif does provide more flexibility.
