I'm just starting to grok the process container instead of VM model. It's valuable to read a writeup like this, it really gives a sense of the different flavor process containers have in production.

I'm still a little mystified by complex setups. Installing stuff as the correct user, adding a big group of database users, stuff like that seems pretty tedious in shell. I guess that's more of a provisioning issue though.

Articles like this make me realize i don't care much what the environment actually is, I care about getting that environment configured correctly with as little effort as possible.

Nice article. I'll add from my own experiences: use squid-deb-proxy; it will save you an immense amount of time when working with docker and ubuntu/debian, or in any situation where you're repeatedly pulling the same packages from aptitude.

I'm using, and highly recommend, apt-cacher-ng: http://www.unix-ag.uni-kl.de/~bloch/acng/

apt-cacher-ng is great as well, they both do the job, squid-deb-proxy just requires a little less configuration since it automatically broadcasts itself to clients on the LAN.

Thanks so much for sharing this. Like previous posters have stated, blog posts describing REAL WORLD usage examples of Docker in systems more complex than "here's a LAMP stack in Docker"* are extremely helpful at this point in the game.

As Docker matures the need for these case studies becomes more apparent. Thanks again for sharing.

* Not to downplay those initial examples. Without the baby steps those examples provided, I would've been lost at the beginning.

This may be a bit germane to the topic, but does anyone know if Ubuntu 14.04 will have docker, as in running on it (and not running 14.04 inside docker).

Upstream Debian is moving very aggressively to package Docker, so I think Ubuntu will automatically benefit from that in future releases. I'm not sure about exact timing though.

There is an 'docker.io' package in Ubuntu trusty (14.04) at present, though it's only 0.7.6, you'll probably tell us like the rvm maintainer, "we were not involved with this packaging effort, they did not consult us, and it's absolutely too old for me to recommend it for actual use by anyone."

Even if it's on a much smaller time scale...

Your website is broken on firefox. Lots of horizontal scrolling that shouldn't be there.

Thanks mate, now fixed :)

We're starting to move our system into containers - early days and there is a lot to learn. It feels like we are in the Cambrian explosion of containerization - many different theories/opinions on best practice. Articles that describe real-life experiences are really valuable.
