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.
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
package resources with Chef.
This recipe also sets up a local cache directory for preseeding packages.
apt-cacher-ng package and service so the system can
provide APT caching. You can check the usage report at
cacher-client recipe, so it helps seed itself.
Configures the node to use the
apt-cacher-ng server as a client.
This LWRP provides an easy way to manage additional APT repositories.
Adding a new repository will notify running the
- :add: creates a repository file and builds the repository listing
- :remove: removes the repository file
- 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
- components: package groupings..when it doubt use
- deb_src: whether or not to add the repository as a source repo as
well - value can be
- key_server: the GPG keyserver where the key for the repo should be retrieved
- key: if a
key_serveris 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.
- 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.
- immediate_cache_rebuild: if the APT cache should be updated after repository
addition - value can be

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.
- :add: creates a preferences file under /etc/apt/preferences.d
- :remove: Removes the file, therefore unpin the package
- package_name: name attribute. The name of the package
- pin: The package version/repository to pin
- pin_priority: The pinning priority aka "the highest package version wins"
# 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
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.
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.
