------------------------------------------
Summary: Health checking only on 127.0.0.1 is limiting.
Key: MESOS-6517
URL: https://issues.apache.org/jira/browse/MESOS-6517
Project: Mesos
Issue Type: Improvement
Reporter: Alexander Rukletsov
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.
