puppet-openvpnas

This is a Puppet module for managing the OpenVPN Access Server. Currently it only contains Puppet types and providers, but that will change in the future.

Usage

Installing OpenVPN Access Server

To install OpenVPN Access Server from the official apt/yum repositories is as simple as:

include ::openvpnas

openvpnas_config

To define server configuration parameters use the openvpnas_config type:

openvpnas_config { 'vpn.tls_refresh.interval':
  value => '100',
}

You can get a list of configuration keys and their current values with

$ /usr/local/openvpn_as/scripts/sacli ConfigQuery

To convert current Access Server configuration into Puppet code use

$ puppet resource openvpnas_config

openvpnas_userprop

To define Access Server user properties use the openvpnas_userprop type:

openvpnas_userprop { 'openvpn-prop_superuser':
  value => 'true',
}

The resource parameter "name" (defaults to resource title) must consist of three parts:

1. User or group name (e.g. "DEFAULT" or "openvpn")
2. A dash
3. Name of the user property to managed (e.g. "prop_superuser")

If the syntax of the title is wrong catalog compilation will fail.

In the user/group name part only word characters, "." and "_" are allowed. If your usernames contain other characters please let us know or, better yet, modify the "name" parameter's validation regexp in lib/puppet/type/openvpnas_userprop.rb and issue a pull request.

You can get a list of current user properties with

$ /usr/local/openvpn_as/scripts/sacli UserPropGet

To convert current user properties into Puppet code use

$ puppet resource openvpnas_userprop

Defining settings in Hiera for automatic lookup of class parameters

It is also possible to define all settings in Hiera and just include openvpnas module in your manifest, which will then automatically lookup the class parameters from Hiera data. Here is an example of Hiera data:

openvpnas::package_ensure: installed
openvpnas::service_ensure: running
openvpnas::service_enable: true
openvpnas::service_name: openvpnas
openvpnas::config:
  vpn.tls_refresh.interval:
    ensure: present
    value: '100'
openvpnas::userprop:
  openvpn-prop_superuser:
    ensure: present
    value: 'true'

To convert current Access Server configuration and user properties into Hiera values use the following commands and adjust the top level keys

$ puppet resource openvpnas_config --to_yaml
$ puppet resource openvpnas_userprop --to_yaml

Note: It was observed that the value of the openvpnas_config resource subscription.saved_state changes often and might not be a good idea to set that to a fixed value with Puppet. It is recommended to use eYAML to encrypt the several secrets that are dumped in plain text.

Warnings

Please note that "sacli" does not do any validation on the data it gets: make sure the values you give it make sense or you risk breaking your VPN server configuration. The types also do not automatically trigger a service restart if configuration is changed.

Also note that all properties need to be passed to the types as strings - even those that look like booleans.

The openvpnas_config and openvpnas_userprop types are ensurable, meaning that you can add arbitrary keys and values to the database, or remove any key that is present there. Use extreme caution when removing keys.
