While I make own packages, I run most of it in docker.
You might also take a look at my dockerhub or github where I cooked some things up.
Most dockers are based on my own base-images of ubuntu:rolling and debian:stable and where applicable preloaded with jemalloc for better performance.
In fact, this site is running on a dockerized apache+phpfpm (ondrej php packages) with a dockerized nginx-proxy in front of it. Nginx is terminating SSL and serving the apt-get sources directly from disk and sends requests for this site to the apache instance.
The dockers rebuild once a day for latest packages and security fixes from ubuntu/debian. They also will rebuild when a package has automaticly been upgraded/build.
