Description

This is a very simple module to manage host entries in /etc/hosts. It works by applying a hash of host resources.

Documented with Puppet Strings at http://ghoneycutt.github.io/puppet-module-hosts/.

Setup

What hosts affects

Generally just the /etc/hosts file though you may use the target attribute of the host resource to manage host entries in other files.

Setup requiremements

The ability to manage /etc/hosts was moved out of Puppet and into a core module at https://github.com/puppetlabs/puppetlabs-host_core and this module relies upon it.

Beginning with hosts

Declare the hosts class.

Usage

The normal use case. If you are not adding the local system by default as shown below, this is a good option. Then you can just add hosts::hosts entries throughout Hiera.

include hosts

Sample profile which implements functionality from previous versions.

# Lookup everything in Hiera using the key 'host_entries' and add the
# local system with its FQDN and IP address.
$hosts = lookup('host_entries', undef, deep, {}) + {
  $facts['networking']['hostname'] => {
    ensure       => present,
    host_aliases => [$facts['networking']['fqdn']],
    ip           => $facts['networking']['ip'],
  }
}

class { 'hosts':
  hosts => $hosts,
}

Limitations

This module officially supports the platforms listed in the metadata.json. It does not fail on unsupported platforms and has been known to work on many, many platforms since its creation in 2010.
