I've been looking for an in depth guide to Docker. Thus looks perfect.

Thanks! Let us know what you want covered.

The one thing I've spent most time getting right with Docker is networking. It's so different from FreeBSD Jails.

I believe a guide with how to setup a dns container with a dns slave container and get other Docker containers to use the dns containers could be a good introduction to how Docker networking actually work.

Networking with Docker is a pretty hefty topic. One of the interesting things talked about in the book in this area is skydock[1], which provides automatic dns registration inside docker when you start your containers. We've found it very handy for simulating a network of real machines!

You may also like to look at Weave[1], which includes an open-source network for Docker and DNS service to find other containers.

Note: I work on Weave.

I work at a company whose main product is a small application using SOA of about 15 services. Managing these 15 services in development is getting to be a nightmare. I would love to know if docker is the right solution to manage these services. Spinning up 15 VMs on a MBP is not really feasible...

It sounds like a very apt use case, unless you need the VM representation for some reason. 15 separate services is no problem for Docker. Hundreds - if not thousands - are quite possible.
