Development repository for Opscode Cookbook apt

branch: master
README.md

Description

This cookbook includes recipes to execute apt-get update to ensure the local APT package cache is up to date. There are recipes for managing the apt-cacher-ng caching proxy and proxy clients. It also includes a LWRP for managing APT repositories in /etc/apt/sources.list.d as well as an LWRP for pinning packages via /etc/apt/preferences.d.

Requirements

Version 1.8.2+ of this cookbook requires Chef 10.16.4 or later.

If your Chef version is earlier than 10.16.4, use version 1.7.0 of this cookbook.

See CHEF-3493 and this code comment for more information on this requirement.

Platform

  • Debian
  • Ubuntu

May work with or without modification on other Debian derivatives.

Recipes

default

This recipe installs the update-notifier-common package to provide the timestamp file used to only run apt-get update if the cache is more than one day old.

This recipe should appear first in the run list of Debian or Ubuntu nodes to ensure that the package cache is up to date before managing any package resources with Chef.

This recipe also sets up a local cache directory for preseeding packages.

cacher-ng

Installs the apt-cacher-ng package and service so the system can provide APT caching. You can check the usage report at http://{hostname}:3142/acng-report.html. The cacher-ng recipe includes the cacher-client recipe, so it helps seed itself.

cacher-client

Configures the node to use the apt-cacher-ng server as a client. If you want to restrict your node to using the apt-cacher-ng server in your Environment, set ['apt']['cacher-client']['restrict_environment'] to true. To use a cacher server (or standard proxy server) not available via search set the atttribute ['apt']['cacher-ipaddress'] and for a custom port set ['apt']['cacher_port']

Resources/Providers

Managing repositories

This LWRP provides an easy way to manage additional APT repositories. Adding a new repository will notify running the execute[apt-get-update] resource immediately.

Actions

  • :add: creates a repository file and builds the repository listing
  • :remove: removes the repository file

Attribute Parameters

  • repo_name: name attribute. The name of the channel to discover
  • uri: the base of the Debian distribution
  • distribution: this is usually your release's codename...ie something like karmic, lucid or maverick
  • components: package groupings..when it doubt use main
  • arch: constrain package to a particular arch like i386, amd64 or even armhf or powerpc. Defaults to nil.
  • deb_src: whether or not to add the repository as a source repo as well - value can be true or false, default false.
  • keyserver: the GPG keyserver where the key for the repo should be retrieved
  • key: if a keyserver is provided, this is assumed to be the fingerprint, otherwise it can be either the URI to the GPG key for the repo, or a cookbook_file.
  • key_proxy: if set, pass the specified proxy via http-proxy= to GPG.
  • cookbook: if key should be a cookbook_file, specify a cookbook where the key is located for files/default. Defaults to nil, so it will use the cookbook where the resource is used.

Examples

# add the Zenoss repo
apt_repository "zenoss" do
  uri "http://dev.zenoss.org/deb"
  components ["main","stable"]
end

# add the Nginx PPA; grab key from keyserver
apt_repository "nginx-php" do
  uri "http://ppa.launchpad.net/nginx/php5/ubuntu"
  distribution node['lsb']['codename']
  components ["main"]
  keyserver "keyserver.ubuntu.com"
  key "C300EE8C"
end

# add the Nginx PPA; grab key from keyserver, also add source repo
apt_repository "nginx-php" do
  uri "http://ppa.launchpad.net/nginx/php5/ubuntu"
  distribution node['lsb']['codename']
  components ["main"]
  keyserver "keyserver.ubuntu.com"
  key "C300EE8C"
  deb_src true
end

# add the Cloudkick Repo
apt_repository "cloudkick" do
  uri "http://packages.cloudkick.com/ubuntu"
  distribution node['lsb']['codename']
  components ["main"]
  key "http://packages.cloudkick.com/cloudkick.packages.key"
end

# add the Cloudkick Repo with the key downloaded in the cookbook
apt_repository "cloudkick" do
  uri "http://packages.cloudkick.com/ubuntu"
  distribution node['lsb']['codename']
  components ["main"]
  key "cloudkick.packages.key"
end

# add the Cloudera Repo of CDH4 packages for Ubuntu 12.04 on AMD64
apt_repository "cloudera" do
  uri "http://archive.cloudera.com/cdh4/ubuntu/precise/amd64/cdh"
  arch "amd64"
  distribution "precise-cdh4"
  components ["contrib"]
  key "http://archive.cloudera.com/debian/archive.key"
end

# remove Zenoss repo
apt_repository "zenoss" do
  action :remove
end

Pinning packages

This LWRP provides an easy way to pin packages in /etc/apt/preferences.d. Although apt-pinning is quite helpful from time to time please note that Debian does not encourage its use without thorough consideration.

Further information regarding apt-pinning is available via http://wiki.debian.org/AptPreferences.

Actions

  • :add: creates a preferences file under /etc/apt/preferences.d
  • :remove: Removes the file, therefore unpin the package

Attribute Parameters

  • package_name: name attribute. The name of the package
  • glob: Pin by glob() expression or regexp surrounded by /.
  • pin: The package version/repository to pin
  • pin_priority: The pinning priority aka "the highest package version wins"

Examples

# Pin libmysqlclient16 to version 5.1.49-3
apt_preference "libmysqlclient16" do
  pin "version 5.1.49-3"
  pin_priority "700"
end

# Unpin libmysqlclient16
apt_preference "libmysqlclient16" do
  action :remove
end

# Pin all packages from dotdeb.org
apt_preference "dotdeb" do
  glob "*"
  pin "origin packages.dotdeb.org "
  pin_priority "700"
end

Usage

Put recipe[apt] first in the run list. If you have other recipes that you want to use to configure how apt behaves, like new sources, notify the execute resource to run, e.g.:

template "/etc/apt/sources.list.d/my_apt_sources.list" do
  notifies :run, resources(:execute => "apt-get update"), :immediately
end

The above will run during execution phase since it is a normal template resource, and should appear before other package resources that need the sources in the template.

Put recipe[apt::cacher-ng] in the run_list for a server to provide APT caching and add recipe[apt::cacher-client] on the rest of the Debian-based nodes to take advantage of the caching server.

If you want to cleanup unused packages, there is also the apt-get autoclean and apt-get autoremove resources provided for automated cleanup.
