What great timing! I was just about to roll my own using etcd, haproxy and a bunch of perl duct tape.

Very excited to take a good look at vulcand.

If you're still interested in doing this for any reason, check out confd [0] for populating templates based on etcd values.

Yes, confd was on my radar and looks promising. In my case, we've already got a wad of perl duct-tape out there and adding etcd was a baby step. Using confd would have been a later step.

Vulcand will likely allow me to replace the whole shebang in one step.

etcd, fleet, deis, and now this are getting me more and more tempted to move from Velociraptor to the Docker ecosystem.

If Deis could run my uptests[0] before Vulcan gets called to re-route things, that'd be awesome.

Top notch technical writeup. We've had our eyes on Vulcand for some time now, though we'd really like to see native TCP support.

Come find us in #deis on Freenode and we'll see if we can help.

This is in pipeline!

TCP would be next step once I make sure the existing feature set is production ready and robust.

This is a golang project, no?
