------------------------------------

             Summary: allow tasks to specify a link to an application-specific 
UI
                 Key: MESOS-1810
                 URL: https://issues.apache.org/jira/browse/MESOS-1810
             Project: Mesos
          Issue Type: Improvement
          Components: slave
            Reporter: brian wickman


Right now Aurora requires you to run special UIs (thermos observers) outside of 
Mesos e.g. via puppet/monit/systemd.  A single observer manages the UI for all 
tasks on that machine.

Instead, we'd like to move to a model where the observer UI is embedded 
directly within the executor, however we'd like to make that UI discoverable 
from the slave.  What I'm proposing is plumbing into the TaskInfo an optional 
URL to expose via the mesos slave to the UI for that task.  This way we don't 
need to reimplement things like sandbox browsing and resource monitoring and 
instead leave that functionality up to the slave, and delegate the 
application-specific information (e.g. "Processes" in the context of Thermos) 
to the application executor UI.
