Simple ambassador container

The Simple Ambassador Container (let's just call it the ambassador) is a reusable container which can be added to your stack to represent a remote service. Using an ambassador your application can discover remote services using docker's standard links features.

10:57 shykes: lastly, we have 2 big limitations for real-world use: logging and reboots
10:57 klizhentas: shykes: can you elaborate on logging?
10:57 shykes: klizhentas: several people have asked me how to integrate their docker setup into syslog or another logging system
10:57 shykes: it's not practical
10:58 shykes: 1) I can't just get a firehose of every container's logs (let alone of a smart subset of them)
10:59 tobstarr: shykes: I would like to have at least some syslog forwarded booted in each container
10:59 backjlack: systemd allows you to do this.
11:00 shykes: 2) it's hard to get a stream of a container's logs in a way that is both reliable and continuous
11:00 fkautz: so, is the problem that they can't hook into syslogd or that it's impracticle for us to provide syslogd support?
11:00 klizhentas: isn't that app specific - so I can tell my container to talk to whatever loggin daemon out there?
