Caching FreeBSD packages with a proxy server

2015 February 21

By setting up apt-cacher-ng 1 in you local development environment, you can save on precious bandwidth when building Chef recipes (or any server side stuff) on your local machine. Below are some of the steps to get this up and running.

Install and configure apt-cacher-ng

In a Mac you can get it via homebrew

brew install apt-cacher-ng

When configuring apt-cacher-ng you need to set the following

  1. Setup the freebsd repository
  2. Set Pigeonhole files for *.txz files for packages and meta.txz, packagesite.txz, digests.txz for metadata files.

TLDR: Place these changes to your vanilla apt-cacher-ng configuration.

/usr/local/etc/apt-cacher-ng$ vagrant plugin list

Finally run apt-cacher-ng like as follows on your mac

launchctl load /usr/local/opt/apt-cacher-ng/homebrew.mxcl.apt-cacher-ng.plist

Update your base vagrant box

I am using Chef’s FreeBSD 10.1 basebox 2 from its bento repository 3 here. I modify the Vagrantfile in the basebox as follows.

Vagrant.configure '2' do |config|
  config.vm.provision 'shell', inline: <<-eos
#!/bin/sh
mkdir -p /usr/local/etc/pkg/repos
cat > /usr/local/etc/pkg/repos/freebsd.conf <<EOF
FreeBSD { url: "pkg+http://<ip-of-mac-vagrant-host>:3142/pkg.FreeBSD.org/\\${ABI}/latest" }
EOF
  eos
end

The basebox’ Vagrantfile is found in ~/.vagrant.d/boxes/chef-VAGRANTSLASH-freebsd10.1/0/vmware_desktop/Vagrantfile in my case.
