19:26 < rektide> how should/could a webapp container get info about the database container it needs?

Thursday June 11, 2014:
10:32 < rektide> is there any means in kubernetes where coordination can happen? how ought my webapp node get the information about where the db node lies?
12:51 < vmarmol> rektide: bburns' demo showcased that. You point it at the generic "DB service" backend and it will discover and send requests to it
12:55 < jbeda> rektide: It works like this.  You specify a ‘service’ that has a name and a ‘label query’.  This then sets up configuration for a small proxy that runs on every worker node.  That proxy will listen on a port per service and forward (simple round robin for now) to one of the backends specified by the ‘label query’.  A set of env variables are set before jobs are started that gives the port for each service based on the name.
