This is a SIMP module

This module is a component of the System Integrity Management Platform, a compliance-management framework built on Puppet.

If you find any issues, they can be submitted to our JIRA.

Module Description

simp-simplib provides a standard library of resources commonly used by SIMP modules but generally suited for any Puppet environment.

Setup

What simplib affects

simplib contains data types, custom types and providers, facts, functions, and a class that expands puppetlabs-stdlib stages.

Setup Requirements

Agents will need to enable pluginsync.

Usage

Please see reference for usage.

Reference

Items not covered by puppet strings are provided below.

See REFERENCE.md for all other reference documentation.

Run stages

See REFERENCE.md#simplibstages

Puppet extensions

The following methods are Puppet extensions in the PuppetX::SIMP::Simplib namespace:

• hostname?
• hostname_only?
• human_sort
• split_port

PuppetX::SIMP::Simplib::hostname?

Determine whether the passed value is a valid hostname, optionally postpended with ':<number>' or '/<number>'.

NOTE: This returns true for an IPv4 address, as it conforms to RFC 1123.

Arguments:

• obj Input to be assessed

Returns: Boolean false if obj is not comprised of ASCII letters (upper or lower case), digits, hyphens (except at the beginning and end), and dots (except at beginning and end), excluding an optional, trailing ':<number>' or '/<number>'

Examples:

  # Returns true
  PuppetX::SIMP::Simplib.hostname?('hostname.me.com')
  PuppetX::SIMP::Simplib.hostname?('hostname.me.com:5454')

  # Returns false
  PuppetX::SIMP::Simplib.hostname?('-hostname.me.com')

PuppetX::SIMP::Simplib::hostname_only?

Determine whether the passed value is a valid hostname.

NOTE: This returns true for an IPv4 address, as it conforms to RFC 1123.

Arguments:

• obj Input to be assessed

Returns: Boolean false if obj is not comprised of ASCII letters (upper or lower case), digits, hyphens (except at the beginning and end), and dots (except at beginning and end)

Examples:

  # Returns true
  PuppetX::SIMP::Simplib.hostname_only?('hostname.me.com')

  # Returns false
  PuppetX::SIMP::Simplib.hostname_only?('-hostname.me.com')
  PuppetX::SIMP::Simplib.hostname_only?('hostname.me.com:5454')

PuppetX::SIMP::Simplib::human_sort

Sort a list of values based on usual human sorting semantics.

Arguments:

• obj Enumerable object to be sorted

Returns: Sorted object

PuppetX::SIMP::Simplib::split_port

Split input string into a [ host, port ] pair

Arguments:

• host_string String to be split into host and port

Returns: Array[ host, port ] Host and port pair

* Returns ``[ nil, nil ]`` if ``host_string`` is ``nil`` or
  an empty string
* Returns ``[ host_string, nil ]`` if ``host_string`` is
  a CIDR address or contains no port
* Port returned is a string

Examples:

  PuppetX::SIMP::Simplib.split_port('myhost.name:5656')
  # returns ['myhost.name','5656']

  PuppetX::SIMP::Simplib.split_port['192.165.3.9']
  # returns ['192.165.3.9',nil]

  PuppetX::SIMP::Simplib.split_port['192.165.3.9/24']
  # returns ['192.164.3.9/24',nil]

  PuppetX::SIMP::Simplib.split_port('[2001:0db8:85a3:0000:0000:8a2e:0370]:'))
  # returns ['[2001:0db8:85a3:0000:0000:8a2e:0370]',nil]
