PortageGT

Overview

PortageGT (short for "Portage using Gentoo") is a replacement Package Provider for Puppet. It was written by Whatbox Inc. to improve server management, and released as on Open Source project under the Apache 2 license. Patches and bug reports are welcome, please see our CLA.

I will also warn you that this module is not completely compatible with the existing Portage Provider. Rather than making assumptions, this provider will throw errors in the event of ambiguity, preferring developer clarification over the possibility of performing an unintended action.

Dependencies

The following packages are necessary for this module.

• dev-lang/ruby >= 1.9.0
• app-admin/puppet >= 3.5.0
• sys-apps/portage
• app-portage/eix

Environment

The following things are assumed:

• /etc/portage/package.use is a directory
• /etc/portage/package.accept_keywords is a directory
• Both of the above are free for modification by puppet
• WARNING: Folders contained within either of these will be automatically removed by this plugin

Installing

PortageGT can be installed from Puppet Forge:

puppet module install Whatbox-portagegt

All code is contained within the lib folder if you wish to place it in an existing module.

To use the PortageGT provider for all of your packages you can set in your manifests, alternatively you can add the provider attribute to any individual packages you desire.

Package {
  provider => 'portagegt'
}

Usage

Using PortageGT should be pretty familiar to anyone already using puppet on Gentoo, the only differences are in the added attributes that may be included in the manifests. The simplest case is the same as it is with existing puppet setups.

package { "vnstat":
    ensure => "1.11-r2";
}

Categories

Name based

package { "net-analyzer/vnstat":
    ensure => "1.11-r2";
}

Attribute based

package { "vnstat":
    ensure   => "1.11-r2",
    category => "net-analyzer";
}

Slots

Name based

package { "dev-lang/php:5.4":
    ensure => latest;
}

package { "dev-lang/php:5.3":
    ensure => absent;
}

Attribute based

package { "dev-lang/python":
    ensure           => latest,
    package_settings => {
        slot => "2.7",
    };
}

package { "dev-lang/python:3.1":
    ensure           => latest,
    package_settings => {
        slot => "3.1",
    };
}

Keywords

package { "sys-boot/grub":
    ensure           => "2.00",
    package_settings => {
        slot     => "2",
        keywords => "~amd64",
    };
}

Repository/Overlay

Specify the latest version of a specific overlay available on your systems, to ensure you don't accidentally build code from the wrong overlay.

package { "www-servers/nginx":
    ensure => latest,
    package_settings => {
        repository => "company-overlay",
    };
}

Use flags

String

package { "www-servers/apache2":
    ensure => latest,
    package_settings => {
        use    => "apache2_modules_alias apache2_modules_auth_basic",
    };
}

Array

package { "www-servers/apache2":
    ensure           => latest,
    package_settings => {
        use => [
            "apache2_modules_alias",
            "-ssl",
        ],
    };
}

Additional emerge options

package { "media-libs/libpng":
    ensure          => latest;
    install_options => ["--oneshot"],
}

Customizing the environment per package

All of your desired environment variables can saved in a named file, as follows:

file {'/etc/portage/env':
    ensure  => directory;
}

file { '/etc/portage/env/notest':
    content => 'FEATURES="-test"';
}

file {'/etc/portage/env/fastmath':
    ensure => file,
    source  => 'puppet:///modules/portage/env/fastmath';
}

String

package { 'dev-ruby/facter':
    ensure          => latest,
    package_settings => {
        environment => 'notest',
    };
}

Array

package { 'media-libs/libpng':
    ensure          => latest,
    package_settings => {
        environment => ['notest', 'fastmath'],
    };
}

Keywords & Use flags on dependencies

If you need to keyword or add use flags to a package without wanting to manage it's version directly.

package { "dev-libs/boost":
    package_settings => {
        use => ["icu", "threads"],
    }
}

eselect

eselect is useful when selecting specific versions from between several slots

PHP

eselect { "php-fpm":
    ensure    => "php5.4",
    module    => "php",
    submodule => "fpm";
}

GCC

eselect { "gcc":
    listcmd => "gcc-config -l",
    setcmd  => "gcc-config",
    ensure  => "x86_64-pc-linux-gnu-4.5.3";
}

Ruby

eselect { "ruby":
    ensure => "ruby19";
}

Python

eselect { "python":
    ensure => "python3.2";
}

eselect { "python2":
    module    => "python",
    submodule => "--python2",
    ensure    => "python2.7";
}

eselect { "python3":
    module    => "python",
    submodule => "--python3",
    ensure    => "python3.2";
}

Profile

eselect { "profile":
    ensure => "default/linux/amd64/13.0";
}

kernel (/usr/src/linux)

eselect { "kernel":
    ensure => "linux-3.7.0-hardened";
}

locale

eselect { "locale":
    ensure => "en_US.UTF-8";
}

Tuning behavior

Some configuration opetions can be found near the start of lib/puppet/provider/package/portagegt.rb that allow tuning of the modules behavior. The defaults cause explict use flag changes to recompile packages, and eix-sync to be run if it has been more than 48 hours since the last sync.

Testing

To install dependencies necessary for running the tests use bundle install, tests can be run with bundle exec rspec. This project attempts to adhere to the Ruby Style Guide, you can verify your changes are in adhere to this guide using bundle exec rubocop.

Note: eix must be installed to test successfully on Gentoo, this is not necessary when running tests from other operating systems.

Roadmap

• Using first-class parameters (PUP-1183)
• More extensive unit testing
• Easier configuration of provider options

Features Omitted

These are features we're not implementing at this time

• package mask
  • using puppet ensure => :held
