This is a general purpose deb and rpm caching proxy. I use it mainly for Vagrant and Docker caching. It's basically a slightly modified squid-deb-proxy, to support RPM. Since the intention is to run it locally on my development machines and not expose it to the network, the default behaviour will cache all requests. To change the default, set environment variable CACHE_ANY to anything other than true:

docker run -d -P -e CACHE_ANY=false <CONTAINER_ID>

The container also supports the following environemt variables:

• EXTRA_MIRROR_DSTDOMAIN : A space separated list of domains to cache. This is only useful if CACHE_ANY is false
• ALLOWED_NETWORKS : Space seperated networks that are allowed to use the cache. It is unlikely you will need to change this, as Docker NATs all requests.
• PKG_BLACKLIST : Space seperated list of packages that will not be cached.

Monit is used to control the start up and management of the Squid proxy. You can access the monit webserver by exposing port 2812 on the Docker host. The user name is monit and password can be found by running:

docker logs <CONTAINER_ID> 2>/dev/null | grep MONIT_PASSWORD
