3. Usage

3.1. validate_platform() function

This function validates if the operating system on the machine that runs manifest matches one of the entires in operatingsystem_support section in metadata.json of the module.

Function needs one parameter: the name of the module to validate.

If the platform returned by the two shell commands:

$ facter operatingsystem
$ facter operatingsystemrelease

can be found in metadata.json then validate_platform() returns true. Otherwise it returns false.

You can use it to automatically validate your module against the current platform. Thus operatingsystem_support section in metadata.json file of your module is the only place where you have to update the information about supported platform.

To validate the platform inside a class defined in a module call the function like in the following snippet:

class abc {

    if !validate_platform($module_name) {
        fail("Platform not supported in module '${module_name}'.")


On some platforms, e.g. CentOS, the command:

$ facter operatingsystemrelease

prints full version, like:


You don't have to use the complete result. You can use arbitrary number of leading characters. The definition:

    "operatingsystem": "CentOS",
    "operatingsystemrelease": [

will be successfully validated on all of the following platforms:

  • CentOS 7.0
  • CentOS 7.0.1406
  • CentOS 7.0.1964-p23
  • CentOS 7.0-dev
  • CentOS 7.0abcdefghijklm


You will find the exact information about supported platforms in metadata.json file.
