Module Description

The puppet_authorization module generates or changes the auth.conf file using authorization rules written as Puppet resources.

Note that this module is used only for the new auth.conf file used by Puppet Server 2.2.0 and later. If you are using the auth.conf file used by core Puppet, this module will not affect it. See Puppet Server documentation for detailed information about the auth.conf file.

This module allows you to add custom rules to your auth.conf file by writing Puppet resources that can create, modify, or remove the associated rules from the auth.conf file. It allows the auth.conf to be created entirely from Puppet code---you never have to touch the auth.conf file directly.

Setup

Beginning with puppet_authorization

Note that this section applies only to open source Puppet. In Puppet Enterprise, this resource is managed automatically.

The puppet_authorization resource sets up the auth.conf and configures settings that apply globally, rather than being specific to individual rules.

For example, this code:

puppet_authorization { '/etc/puppetlabs/puppetserver/conf.d/auth.conf':
  version                => 1,
  allow_header_cert_info => false
}

...would populate the following corresponding settings into the "auth.conf" file:

authorization: {
  version: 1
  allow-header-cert-info: false
  rules: ...
}

Note that the value for rules in this case would be set to [] if the rules array was not yet present in the file. Otherwise, whatever value was already in the target file for rules is preserved.

The values used above are:

  • version: Currently, 1 is the only supported value and is the default.
  • allow-header-cert-info: Controls whether the identity of the client will be inferred from the client's SSL certificate, when false, or from special X-Client HTTP headers, when true. The default for this setting is false. See Puppet Server documentation for information about disabling HTTPS for Puppet Server and allow-header-cert-info setting.

Usage

The following usage examples assume an empty auth.conf file that looks like this:

authorization: {
  version: 1
  rules: []
}

Add a rule

The main resource to use is puppet_authorization::rule, which manages a single rule in the authorization configuration file (auth.conf). This authorization file also needs to be managed with a resource, which is done with puppet_authorization.

The following declares a resource to manage the top-level structure, followed by a resource to add a rule for controlling access to the "environments" HTTP endpoint:

puppet_authorization::rule { 'environments':
  match_request_path   => '/puppet/v3/environments',
  match_request_type   => 'path',
  match_request_method => 'get',
  allow                => 'your.special.admin',
  sort_order           => 300,
  path                 => '/etc/puppetlabs/puppetserver/conf.d/auth.conf',
}

Here, we've declared that only 'your.special.admin' can access the /puppet/v3/environments endpoint.

Delete a rule

Continuing from the previous example to add the "environments" rule, the following example declares a resource that removes it from the file.

puppet_authorization::rule { 'environments':
  ensure => absent,
  path   => '/etc/puppetlabs/puppetserver/conf.d/auth.conf',
}

When removing a rule, you have only to provide the rule name and path to the configuration file where it can be found. Since rules must have unique names, you don't have to define the other attributes (match_request_path, etc); the rule with the matching name will be removed, regardless.

Configure the catalog endpoint

You can configure the catalog HTTP endpoint for Puppet Server to:

  • Permit an administrative node to access the catalog for any node.
  • Permit other nodes to be able to access their own catalog, but no other node’s catalog.

In this example, we'll configure the rule to apply only to requests made to the production or test directory environments in Puppet.

puppet_authorization::rule { 'catalog_request':
  match_request_path         => '^/puppet/v3/catalog/([^/]+)$',
  match_request_type         => 'regex',
  match_request_method       => ['get','post'],
  match_request_query_params => {'environment' => [ 'production', 'test' ]},
  allow                      => ['$1', 'adminhost.mydomain.com'],
  sort_order                 => 200,
  path                       => '/etc/puppetlabs/puppetserver/conf.d/auth.conf',
}

If the original auth.conf file looked like this:

authorization: {
  version: 1
  allow-header-cert-info: false
  rules: []
}

...then it should look something like this after the new rule is applied:

authorization: {
  version: 1
  allow-header-cert-info: false
  rules: [
      {
          "allow" : [
              "$1",
              "adminhost.mydomain.com",
          ],
          "match-request" : {
              "method" : [
                  "get",
                  "post"
              ],
              "path" : "^/puppet/v3/catalog/([^/]+)$",
              "query-params" : {
                  "environment" : [
                      "production",
                      "test"
                  ]
              },
              "type" : "regex"
          },
          "name" : "catalog_request",
          "sort-order" : 200
      }
  ,
  ]
}

Trigger rule changes

Puppet Server does not automatically start using the new rule definitions in the auth.conf file as they are applied. Before your auth.conf file changes take effect, the Puppet Server service needs to be restarted. Add the following code to each rule resource to restart the service any time rules in the auth.conf file changes.

If you're using open source Puppet Server, add the following code to your rule resource:

notify => Service['puppetserver']

If you're using Puppet Server in PE, add:

notify => Service['pe-puppetserver']

For example, with this code added, the full rule definition might look like this:

puppet_authorization::rule { 'catalog_request':
  match_request_path         => '^/puppet/v3/catalog/([^/]+)$',
  match_request_type         => 'regex',
  match_request_method       => ['get','post'],
  match_request_query_params => {'environment' => [ 'production', 'test' ]},
  allow                      => ['$1', 'adminhost.mydomain.com'],
  sort_order                 => 200,
  path                       => '/etc/puppetlabs/puppetserver/conf.d/auth.conf',
  notify                     => Service['pe-puppetserver'],
}
