Description

The purpose of this module is to configure existing Satellite/Foreman systems for remote execution (REX).

Setup

Import module and publish/promote to appropriate CV/LCE. Configure overrides overrides for the rex::params class. The following two are required, any additional can be tweeked to the desired value.

rex_user = <%= @host.params['remote_execution_ssh_user'] %>
resources = 
---
ssh_authorized_key:
  <% for _key in @host.params['remote_execution_ssh_keys'] do -%>
  <% key = _key.split(' ') -%>
  <%= key[2] %>:
    user: <%= @host.params['remote_execution_ssh_user'] %>
    type: <%= key[0] %>
    key: <%= key[1] %>
  <% end -%>

Following this, simply enable the rex and rex::params classes on the host[s] or host group[s] of your choosing.

Note: If you plan to use a user other than root, you must configure the remote_execution_ssh_user found in the Remote Execution portion of the Settings menu.

What rex affects

This module will creat the REX user, if it is not already present and will manage this users password. It will deploy sudo rules to /etc/sudoers.d/rex. Finally, it will deploy the required ssh keys.

Files affected:

  • user's home dir
  • /etc/passwd
  • /etc/shadow
  • /etc/sudoers.d/rex
  • $home_dir/.ssh/authorized_keys

Warnings:

  • this module will not work correctly if using ldap (or other external) user
  • this module will house the users encrypted password in the UI
  • this module could cause unexpected security risks, if not properly configured

Setup Requirements

The hash_resources module must be installed for this module to function correctly. Additionally, if the desired ssh user for REX is not root, this must be configured prior to enableing this module.

Beginning with rex

  • import the module
  • configure override for resources
  • enable module

Usage

Additional user configurable parameters are available via the params class. These paramaters can be used to manage the REX user's password, set password policies, and the user comments field.

Reference

Limitations

This module will not work with external users for REX ssh user.

Development

Contributions welcome!
