apt-get cache?

[jrgifford]

Is there a way to build these and make use of a apt-get cache such as what is outlined here? I have a slow connection, and I like to build my own boxes for various projects, with minor tweaks here and there.

Previously, I ran a squid-deb-proxy on my LAN and would install that package first, then would update and configure the boxes from that. Is that doable with packer/these images?

have you tried to set http_proxy and https_proxy when building the boxes with Packer?
As far as I can tell all packages are loaded via my local squid.

You have to have squid configured to cache .bz etc. like this:

refresh_pattern -i .rpm$ 129600 100% 129600 
refresh_pattern -i .bz2$ 129600 100% 129600 
refresh_pattern -i .deb$ 129600 100% 129600 

and you need a large object size:

 maximum_object_size 500 MB

and if the cache should survive a restart:

 cache_dir ufs /usr/local/var/cache/squid 10000 16 256
