gssproxy

Manage and configure the gssproxy service

Description
Usage - Configuration options and additional functionality
Limitations - OS compatibility, etc.
Development - Guide for contributing to the module

Description

The gssproxy service is used in a number of contexts to proxy kerberos authentication for various applications. The most common use is with Kerberized NFS.

This module will setup the gssproxy service, but leave defining them to you. See Usage - Configuration options and additional functionality for more information.

Usage

By default this class will define zero services for gssproxy to work with. The idea here is that the service using gssproxy probably requires its own configuration settings there, and it makes more sense to export an interface for other services (such as nfs) to define their settings along side the service itself.

But if you want to instead manage the gssproxy interface here you can do so with something like:

class { 'gssproxy':
  services => {
    'service/nfs-client' => {
      'settings' => {
         'mechs' => 'krb5',
         'cred_store' => [
            'keytab:/etc/krb5.keytab',
            'ccache:FILE:/var/lib/gssproxy/clients/krb5cc_%U',
            'client_keytab:/var/lib/gssproxy/clients/%U.keytab' ],
         'cred_usage' =>  'initiate',
         'allow_any_uid' => 'yes',
         'trusted' => 'yes',
         'euid' => 0,
    } },

    'service/nfs-server' => {
      'settings' =>
        'mechs' => 'krb5',
        'socket' => '/run/gssproxy.sock',
        'cred_store' => 'keytab:/etc/krb5.keytab',
        'trusted' => 'yes',
        'kernel_nfsd' => 'yes',
        'euid' => 0,
    }
  }
}

or in hiera

gssproxy::services:
  'service/nfs-client':
    settings:
       mechs: krb5
       cred_store:
         - keytab:/etc/krb5.keytab
         - ccache:FILE:/var/lib/gssproxy/clients/krb5cc_%U
         - client_keytab:/var/lib/gssproxy/clients/%U.keytab
       cred_usage:  initiate
       allow_any_uid: 'yes'
       trusted: 'yes'
       euid: 0

  'service/nfs-server':
    settings:
      mechs: krb5
      socket: /run/gssproxy.sock
      cred_store: keytab:/etc/krb5.keytab
      trusted: 'yes'
      kernel_nfsd: 'yes'
      euid: 0

Include usage examples for common use cases in the Usage section. Show your users how to use your module to solve problems, and be sure to include code examples. Include three to five examples of the most important or common tasks a user can accomplish with your module. Show users how to accomplish more complex tasks that involve different types, classes, and functions working in tandem.

Limitations

If you disable the management of the system service, the service defined type will not automatically notify the system service of the change as it may be undefined or have an unknown name.

Development

Development takes place within the github repo.

Reference

Classes

Public Classes

gssproxy: Manage and configure gssproxy

Private Classes

gssproxy::config: load the vendor default gssproxy.conf
gssproxy::install: Install the gssproxy package(s)
gssproxy::system_service: manage the gssproxy service(s)

Defined types

gssproxy::service: Create gssproxy a service definition

Classes

`gssproxy`

This class can install, configure, and manage the gssproxy service. On most systems gssproxy ships with some services pre-defined.

To make it easier to integrate this module with the class that manages those external services this class will provide zero gssproxy services. By default any unmanaged services will be removed. You can disable this.

Examples

include gssproxy

class { 'gssproxy':
  gssproxy_services => {
    'service/nfs-server' => {
       'settings' => {
         'mechs'       => 'krb5',
         'socket'      => '/run/gssproxy.sock',
         'cred_store'  => 'keytab:/etc/krb5.keytab',
         'trusted'     => 'yes',
         'kernel_nfsd' => 'yes',
         'euid'        => 0,
       }
    }
  }
}

Parameters

The following parameters are available in the gssproxy class:

manage_packages
packages
packages_ensure
manage_conf
gssproxy_conf
gssproxy_conf_d
gssproxy_conf_d_purge_unmanaged
manage_system_services
system_services
system_services_ensure
system_services_enable
defaults
gssproxy_services

`manage_packages`

Data type: Boolean

Boolean to enable/disable the package managment of this module Default is to manage packages

`packages`

Data type: Array[String[1]]

Array of packages for this program Default: [ 'gssproxy' ]

`packages_ensure`

Data type: String

Passed directly to the ensure parameter of the listed packages Default: 'present'

`manage_conf`

Data type: Boolean

Boolean to enable/disable the config management of this module Default is to manage the config

`gssproxy_conf`

Data type: Stdlib::Absolutepath

The absolute path to the gssproxy primary config. Default is /etc/gssproxy/gssproxy.conf

`gssproxy_conf_d`

Data type: Stdlib::Absolutepath

The absolute path to the gssproxy include directory Default is /etc/gssproxy

`gssproxy_conf_d_purge_unmanaged`

Data type: Boolean

Boolean to remove any unmanaged files within $gssproxy_conf_d Default is true

`manage_system_services`

Data type: Boolean

Boolean to manage the system service (systemd unit) state Default is true

`system_services`

Data type: Array[String[1]]

Array of system services for gssproxy Default: [ 'gssproxy' ]

`system_services_ensure`

Data type: Stdlib::Ensure::Service

The system service ensure state Default: 'running'

`system_services_enable`

Data type: Boolean

The system service enable state Default: true

`defaults`

Data type: Hash[String, Variant[Data, Array[String[1]], Undef]]

The default settings for gssproxy. Default: No settings

`gssproxy_services`

Data type: Optional[Hash[String, Variant[Data, Array[String[1]], Undef]]]

A hash of gssproxy services to configure. Running gssproxy without any configured services is weird. But it probably makes more sense to configure them in the service you are interfacing with rather than try to maintain them over here. Default: No services

Default value: undef

Defined types

`gssproxy::service`

This resource creates gssproxy service definitions. If you using your own management of the gssproxy system service, you will need to setup your own notifications. If you are using this module to manage the system service notifications should happen automatically.

Examples

gssproxy::service { 'service/nfs-client':
  settings          => {
    'mechs'         => 'krb5',
    'cred_store'    => [
      'keytab:/etc/krb5.keytab',
      'ccache:FILE:/var/lib/gssproxy/clients/krb5cc_%U',
      'client_keytab:/var/lib/gssproxy/clients/%U.keytab' ],
    'cred_usage'    => 'initiate',
    'allow_any_uid' => 'yes',
    'trusted'       => yes,
    'euid'          => 0,
}

gssproxy::service { 'service/nfs-server':
  settings        => {
    'mechs'       => 'krb5',
    'socket'      => '/run/gssproxy.sock',
    'cred_store'  => 'keytab:/etc/krb5.keytab',
    'trusted'     => 'yes',
    'kernel_nfsd' => 'yes',

settings

`section`

Data type: String

Name of the section within the config file. It defaults to the resource title.

Default value: $title

`force_this_filename`

Data type: Optional[Stdlib::Absolutepath]

Ignore any built in logic to try and simplify placement. Just use this filename. Default: unset

Default value: undef

`filename`

Data type: Optional[Pattern[/^\d\d-/]]

Name of the config file to write out. The filename must start with two digits and a - or gssproxy will not see it. The filename must end in .conf or gssproxy will not see it.

Default value: undef

`order`

Data type: Integer

gssproxy requires config files to start with a 2 digit number and then a -. So we permit just setting the number prefix. Default: 50

Default value: 50

`settings`

Data type: Hash[String, Variant[Data, Array[String[1]], Undef]]

A key value hash of what to write out into the config file. A key that can be specified multiple times should set an array when they wish to set multiple values.

See the examples.

      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
