Currently with deis you can run deis logs, but it's a single request-response that returns the current app logs and ends. Nor does deis run tail -f work since that isn't (yet) a long-running, duplex connection. Users should be able to get live tailing of logs.

This was requested by user kfarrell on IRC. See also #117.

Also a way to specify the number of line (-n) would be a nice addition.

@nathansamson just pipe the output to tail:

$ deis logs | tail -n 1

@bacongobbler that would still be a performance problem (useless network traffic)

I hope to solve this by streaming from the log file for changes. The issue with that is, again, WSGI does not support websockets or other long-running requests.

basically we could resolve this by enabling the controller to create a tail session in deis-logger, which then the controller would return the URL to the tail session in the response. The client would then connect to the session. This is very similar to Heroku's current infrastructure layout as shown in their client unit tests.

@paralin This is blocked by the TTY broker on our open roadmap. If this feature is important to you, we'd love to see you at next Thursday's open roadmap meeting, and we can share more details about its progress and blockers. More details on our roadmap planning meetings: http://docs.deis.io/en/latest/roadmap/planning/

I'll be sending out the details on the meeting early next week to our deis-users mailing list. I'd encourage you to join that as well.
