The apt module provides a simple interface for managing APT source, key, and definitions with Puppet.
The apt module automates obtaining and installing software packages on *nix systems.
*Note: While this module allows the use of short keys, we strongly recommend that you do not use short keys, as they pose a serious security issue by opening you up to collision attacks.
What apt affects:
purge_preferences
or purge_preferences_d
parameters to 'true' will destroy any existing configuration that was not declared with Puppet. The default for these parameters is 'false'.sources.list
file and sources.list.d
directory
purge_sources_list
and purge_sources_list_d
parameters to 'true' will destroy any existing content that was not declared with Puppet. The default for these parameters is 'false'.To begin using the apt module with default parameters, declare the class.
include apt
Puppet code that uses anything from the apt module requires that the core apt class be declared.
Using the apt module consists predominantly of declaring classes that provide the desired functionality and features.
apt
provides a number of common resources and options that are shared by the various defined types in this module, so you must always include this class in your manifests.
The parameters for apt
are not generally required and are predominantly for development environment use cases.
class { 'apt':
always_apt_update => false,
apt_update_frequency => undef,
disable_keys => undef,
proxy_host => false,
proxy_port => '8080',
purge_sources_list => false,
purge_sources_list_d => false,
purge_preferences_d => false,
update_timeout => undef,
fancy_progress => undef
}
Puppet will manage your system's sources.list
file and sources.list.d
directory but will do its best to respect existing content.
If you declare your apt class with purge_sources_list
, purge_sources_list_d
, purge_preferences
and purge_preferences_d
set to 'true', Puppet will unapologetically purge any existing content it finds that wasn't declared with Puppet.
Installs the build depends of a specified package.
apt::builddep { 'glusterfs-server': }
Forces a package to be installed from a specific release. This class is particularly useful when using repositories, like Debian, that are unstable in Ubuntu. The cfg_files parameter controls wether newer or older configuration files should be used or only unchanged configuration files should be updated. Cfg_missing forces the provider to install all missing configuration files. Both are optional.
apt::force { 'glusterfs-server':
release => 'unstable',
version => '3.0.3',
cfg_files => 'unchanged',
cfg_missing => true,
require => Apt::Source['debian_unstable'],
}
You can additionally set the following attributes:
cfg_files
: "new", "old", "unchanged" or "none" (default). "new" will overwrite all existing configuration files with newer ones, "old" will force usage of all old files and "unchanged" only updates unchanged config files whereas setting "none" will don't do anything but providing backward-compatability with existing puppet manifests.cfg_missing
: "true" or "false". Setting cfg_missing to false will provide backward compatability whereas setting true will add an aptitude/apt-get parameter which checks and installs missing configuration files for the selected package.A native Puppet type and provider for managing GPG keys for APT is provided by this module.
apt_key { 'puppetlabs':
ensure => 'present',
id => '1054B7A24BD6EC30',
}
You can additionally set the following attributes:
source
: HTTP, HTTPS or FTP location of a GPG key or path to a file on the
target host;content
: Instead of pointing to a file, pass the key in as a string;server
: The GPG key server to use. It defaults to keyserver.ubuntu.com;keyserver_options
: Additional options to pass to --keyserver
.Because apt_key is a native type, it can be used in and queried for with MCollective.
Adds a key to the list of keys used by APT to authenticate packages. This type uses the aforementioned apt_key
native type. As such, it no longer requires
the wget
command on which the old implementation depended.
apt::key { 'puppetlabs':
key => '1054B7A24BD6EC30',
key_server => 'pgp.mit.edu',
}
apt::key { 'jenkins':
key => '9B7D32F2D50582E6',
key_source => 'http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key',
}
Adds an apt pin for a certain release.
apt::pin { 'karmic': priority => 700 }
apt::pin { 'karmic-updates': priority => 700 }
apt::pin { 'karmic-security': priority => 700 }
Note you can also specifying more complex pins using distribution properties.
apt::pin { 'stable':
priority => -10,
originator => 'Debian',
release_version => '3.0',
component => 'main',
label => 'Debian'
}
If you wish to pin a number of packages you may specify the packages as a space
delimited string using the packages
attribute or pass in an array of package
names.
When you wish to hold a package in Puppet, it should be done by passing in 'held' as the ensure attribute to the package resource. However, a lot of public modules do not take this into account and generally do not work well with an ensure of 'held'.
Moreover, when Puppet is told to hold a package, it holds it at the current version installed; there is no way to tell it to both install a specific version and hold that version, unless you use an exec resource that wraps dpkg --set-selections
or apt-mark
.
At first glance, it seems this issue could also be solved by passing the version required to the ensure attribute---but that only means that Puppet will install that version after it processes the package. It does not inform apt that we want this package to be held; that is, should another package want to upgrade this one (because of a version requirement in a dependency, for example), we want apt to refuse.
To solve this issue, use apt::hold. Implement this by creating a preferences file with a priority of 1001. Under normal circumstances, this preference will always win. Because the priority is > 1000, apt will maintain the required version, downgrading the current package if necessary.
With this, you can now set a package's ensure attribute to 'latest' but get the version specified by apt::hold:
apt::hold { 'vim':
version => '2:7.3.547-7',
}
Alternatively, if you want to hold Vim at version 7.3.*, you can pass in a version with a glob:
apt::hold { 'vim':
version => '2:7.3.*',
}
Adds a ppa repository using add-apt-repository
.
apt::ppa { 'ppa:drizzle-developers/ppa': }
Sets the default apt release. This class is particularly useful when using repositories, like Debian, that are unstable in Ubuntu.
class { 'apt::release':
release_id => 'precise',
}
Adds an apt source to /etc/apt/sources.list.d/
.
apt::source { 'debian_unstable':
comment => 'This is the iWeb Debian unstable mirror',
location => 'http://debian.mirror.iweb.ca/debian/',
release => 'unstable',
repos => 'main contrib non-free',
required_packages => 'debian-keyring debian-archive-keyring',
key => '8B48AD6246925553',
key_server => 'subkeys.pgp.net',
pin => '-10',
include_src => true,
include_deb => true
}
If you would like to configure your system so the source is the Puppet Labs APT repository:
apt::source { 'puppetlabs':
location => 'http://apt.puppetlabs.com',
repos => 'main',
key => '1054B7A24BD6EC30',
key_server => 'pgp.mit.edu',
}
Runs apt-get update
, updating the list of available packages and their versions without installing or upgrading any packages.
The update runs on the first Puppet run after you include the class, then whenever notify => Exec['apt_update']
occurs---this should happen when config files get updated or other relevant changes occur. If you set the always_apt_update
parameter, the update will run on every Puppet run.
There are a few facts included in the apt module describing the state of the apt system:
apt_updates
--- the number of updates available on the systemapt_security_updates
--- the number of updates which are security updatesapt_package_updates
--- the package names that are available for update. In Facter 2.0 and later, this will be a list type; in earlier versions, it is a comma-delimited string.apt_update_last_success
--- The date in epochtime that apt-get update
last ran successfully. This is determined by reading the mtime of the file /var/lib/apt/periodic/update-success-stamp
. That file is generated by the /etc/apt/apt.conf.d/15update-stamp
file.apt::sources: 'debian_unstable': location: 'http://debian.mirror.iweb.ca/debian/' release: 'unstable' repos: 'main contrib non-free' required_packages: 'debian-keyring debian-archive-keyring' key: '9AA38DCD55BE302B' key_server: 'subkeys.pgp.net' pin: '-10' include_src: 'true' include_deb: 'true' 'puppetlabs': location: 'http://apt.puppetlabs.com' repos: 'main' key: '1054B7A24BD6EC30' key_server: 'pgp.mit.edu'
The apt module is mostly a collection of defined resource types, which provide reusable logic that can be leveraged to manage APT. It provides smoke tests for testing functionality on a target system, as well as spec tests for checking a compiled catalog against an expected set of resources.
This test will set up a Puppet Labs APT repository. Start by creating a new smoke test, called puppetlabs-apt.pp, in the apt module's test folder. In this test, declare a single resource representing the Puppet Labs APT source and GPG key:
apt::source { 'puppetlabs':
location => 'http://apt.puppetlabs.com',
repos => 'main',
key => '1054B7A24BD6EC30',
key_server => 'pgp.mit.edu',
}
This resource creates an APT source named puppetlabs and gives Puppet information about the repository's location and the key used to sign its packages. Puppet leverages Facter to determine the appropriate release, but you can set this directly by adding the release type.
Check your smoke test for syntax errors:
$ puppet parser validate tests/puppetlabs-apt.pp
If you receive no output from that command, it means nothing is wrong. Then, apply the code:
$ puppet apply --verbose tests/puppetlabs-apt.pp
notice: /Stage[main]//Apt::Source[puppetlabs]/File[puppetlabs.list]/ensure: defined content as '{md5}3be1da4923fb910f1102a233b77e982e'
info: /Stage[main]//Apt::Source[puppetlabs]/File[puppetlabs.list]: Scheduling refresh of Exec[puppetlabs apt update]
notice: /Stage[main]//Apt::Source[puppetlabs]/Exec[puppetlabs apt update]: Triggered 'refresh' from 1 events>
The above example uses a smoke test to lay out a resource declaration and apply it on your system. In production, you might want to declare your APT sources inside the classes where they’re needed.
Adds the necessary components to get backports for Ubuntu and Debian. The release name defaults to $lsbdistcodename
. Setting this manually can cause undefined behavior (read: universe exploding).
By default this class drops a Pin-file for Backports, pinning it to a priority of 200. This is lower than the normal Debian archive, which gets a priority of 500 to ensure that packages with ensure => latest
don't get magically upgraded from Backports without your explicit permission.
If you raise the priority through the pin_priority
parameter to 500, identical to the rest of the Debian mirrors, normal policy goes into effect and the newest version wins/becomes the candidate apt will want to install or upgrade to. This means that if a package is available from Backports it and its dependencies will be pulled in from Backports unless you explicitly set the ensure
attribute of the package
resource to installed
/present
or a specific version.
This module should work across all versions of Debian/Ubuntu and support all major APT repository management features.
Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.
We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
You can read the complete module contribution guide on the Puppet Labs wiki.
