3.3 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below

I'll bet that at one time or another, you've wanted the ability to manage certain resources on a node--but only once. For example, you may want to manage user accounts with a defined initial password, but give your users the ability to update their password.


It's very simple. Just add the word manageonce before your resource declaration and it will only be managed one time. This will currently work for file and user resource types only.

manageonce::file { '/root/.bashrc':
  owner   => 'root',
  group   => 'root,
  mode    => '0644,
  content => file('mymod/bashrc'),

Alternatively, you can declare any resource type by using the manageonce type:

manageonce { "puppet master host entry":
  resourcetype  => 'host',
  resourcetitle => 'master.puppetlabs.vm',
  parameters    => { 'ip =>', 'aliases' => ['puppet, master'] }

Finally, if you'd like to continue managing the resource, except for a certain parameter or two, then you can pass an array of parameter names as $onlyonce. Any parameters in that list will be managed one time only.

manageonce::user { 'joe':
  ensure   => present,
  password => hiera('defaults::user::initialpassword'),
  onlyonce => ['password'],


This will currently only run on Unix-like platforms due to the hard-coded path for the external facts.d directory.


I take no liability for the use of this module. As this uses standard Ruby, the only reason that it won't work anywhere Puppet itself does is that it's got a hard-coded path. (TODO: fix this!)

I have not yet validated on anything other than CentOS.
