This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.
I add a simple function that checks if a directory named something similar to
~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.
def local_cache(basebox_name) cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name) partial_dir = cache_dir.join('partial') partial_dir.mkdir unless partial_dir.exist? cache_dir end
I put this funcion in my
Vagrantfile so I can use it like this:
Vagrant::Config.run do |config| config.vm.box = "opscode-ubuntu-12.04" config.vm.box_url = "https://opscode-vm.s3.amazonaws.com/vagrant/boxes/opscode-ubuntu-12.04.box" cache_dir = local_cache(config.vm.box) config.vm.share_folder "v-cache", "/var/cache/apt/archives/", cache_dir end
The result is that the apt cache inside the VM (
/var/cache/apt/archives/) is always mounted on the same directory on the host (
~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/ in this case) and apt just download the packages the first time or if the package has been updated.
This save me a lot of time while I'm developing or debuging Chef cookbooks. Mostly when my recipes need to install many packages.
