## Common questions

### What Docker port and volume should I expose for the sameersbn/apt-cacher-ng image?

Publish port 3142 and mount a persistent directory to /var/cache/apt-cacher-ng, for example /srv/docker/apt-cacher-ng:/var/cache/apt-cacher-ng.

### Which APT client setting keeps HTTPS repositories from being tunneled through apt-cacher-ng?

Add Acquire::https::Proxy "DIRECT" to the client configuration. Without that setting, apt can tunnel HTTPS repositories through the cacher.

### Does apt-cacher-ng include a web interface?

Yes, it has a web frontend for viewing statistic reports and triggering actions, such as importing already available package files into the cache.

### How can I restrict which clients may use the cache?

Use access controls such as IP interface, libwrap, inetd, or iptables, and you can also use a target port filter.
