Installation in Production

• Clone the module into your /etc/puppet/modules directory:

    cd /etc/puppet/modules
    git clone git://github.com/garthk/puppet-apt-cacher-ng apt-cacher-ng
  

• Edit the definition for your server to include apt-cacher-ng, perhaps specifying version:

    class { 'apt-cacher-ng':
      # version => '0.4.6-1ubuntu1',
    }
  

  The server will be available at the default port (3142).

  The server will not use itself as a cache by default.

• Edit the definition for your clients to include apt-cacher-ng::client:

    class { 'apt-cacher-ng::client':
      server  => "192.168.31.42:3142",
    }
  

• To specify more than one server:

    class { 'apt-cacher-ng::client':
      servers => ["192.168.30.42:3142", "192.168.31.42:3142"],
    }
  

• To disable fallback to direct access if the proxy is not available:

    class { 'apt-cacher-ng::client':
      autodetect => false,
      server     => "192.168.31.42:3142",
    }
  

  Per askubuntu:54099, you'll need to do this on older Ubuntu and Debian releases. Lucid and Squeeze support Acquire::http::ProxyAutoDetect; Karmic and Lenny don't.

Providing an apt cache for your Vagrant virtual machines

To install apt-cacher-ng on a fresh box in Vagrant:

vagrant up aptcache

The Vagrantfile specifies a box named aptcache providing its service from http://192.168.31.42:3142. You should be able to browse to it from your host OS to manage it.

Using the apt cache

To configure your own Vagrant box to access the aptcache box:

• Configure your VM for host-only networking, by adding the following line to your Vagrantfile:

    config.vm.network :hostonly, "192.168.31.2"
  

  (Change the final octet (2) to make sure it's unique on your machine. Don't use 1: it'll probably be used by your host OS for its vboxnet0 adapter.)

• Inside your box, create /etc/apt/apt.conf.d/71proxy with the line:

    Acquire::http { Proxy "http://192.168.31.42:3142"; };
  

  If you're using Puppet Provisioning, put this in your manifest_file, e.g. my_manifest.pp:

    file { "/etc/apt/apt.conf.d/71proxy": 
      owner   => root,
      group   => root,
      mode    => '0644',
      content => 'Acquire::http { Proxy "http://192.168.31.42:3142"; };',
    }
  

  You could also install the Puppet module and use apt-cacher-ng::client as above.

Testing

To perform a smoke test:

make smoke

To smoke test both the module and the Vagrantfile's manifest_file:

make test

To test the module properly, install Vagrant and:

make vm
