# APT-CACHER Used by Debian-like Linux distros, will get configured under guest's `/var/cache/apt-cacher-ng` and only works with NFS-shared folders since `vboxsf` is enforcing `vagrant`-user and `apt-cacher` is running under `apt-cacher-ng` user. To manually enable it: ```ruby Vagrant.configure("2") do |config| config.vm.box = 'some-debian-box' config.cache.enable :apt_cacher end ``` One use case for this bucket is if you are using containers inside your VMs, e.g VirtualBox -> LXC. This would allow you to reuse packages without sharing folder inside VirtualBox: # install apt-cacher on (Host)-VM $ sudo apt-get install apt-cacher-ng # get the IP for eth0 interface $ ifconfig eth0 |grep "inet addr"|awk '{print $2}' |cut -c6-20 # configure mirror on for your docker/LXC instances: $ echo 'Acquire::http { Proxy "http://X.X.X.X:3142"; };' > /etc/apt/apt.conf.d/10mirror # check, if working by tailing log on (Host)-VM, while installing packages on (Guest)-VMs $ tail -f /var/log/apt-cacher-ng/apt-cacher.log
