I use https://github.com/michaelsauter/crane.

It has held up really well for me.

There's also this one: https://github.com/azukiapp/azk

I'm using azk[0] for my development workflow with 30+ services defined in one Azkfile.js. It automatically setups http load balancers and dns services for you, no need for container linking.
