Cyrille Chépélov commented on MESOS-6517:
-----------------------------------------
(also, some systems, such as some Debians, like to have 127.0.0.1 and 127.0.1.1
as local addresses, for different purposes...)
> Health checking only on 127.0.0.1 is limiting.

> Project: Mesos
> Issue Type: Improvement
> Reporter: Alexander Rukletsov
> Labels: health-check, mesosphere
>
> As of Mesos 1.1.0, HTTP and TCP health checks always use 127.0.0.1 as the
> target IP. This is not configurable. As a result, tasks should listen on all
> interfaces if they want to support HTTP and TCP health checks. However, there
> might be some cases where tasks or containers will end up binding to a
> specific IP address.
> To make health checking more robust we can:
> * look at all interfaces in a given network namespace and do health check on
> all the IP addresses;
> * allow users to specify the IP to health check;
> * deduce the target IP from task's discovery information.
