 Description   

We need to document that a DC/OS nodes hostname should resolve to a locally bindable IP address. If the hostname of a node is set to a non-local IP address, it might lead to undefined behavior from applications due to the fact that the most applications resolve the hostname to bind to local address.

This ticket is deferred to DC/OS 1.10.2 as part of a bulk move (labels=bulk-defer-to-1.10.2-20171106). Please make sure this targeted fixVersion is correct, as well as the workflow status. �

Are you able to do that for 1.10.2? If not, can you please update the fixVersion in here? Thanks

Avinash Sridharan – can you provide a bit more context about this? Is this something a user would configure at install time?

Comment by Seth Mason (Inactive) [ 25/Jan/18 ]

Avinash Sridharan can you assign this to an engineer to work with Thomas King to update the documentation? RC1 is Friday.

As we continue to deferring this ticket, I am downgrading it now.

Comment by Marco Monaco [ 23/May/18 ]

Bulk change: please update the fixVersion DC/OS 1.11.2 as this has been released already.

Sarah Stegall Could you please work with Ben Wood and me to document this ?

All DC/OS node host names should resolve to *locally bindable* IP addresses. Most applications require host names to resolve by binding to a local IP address to function correctly. Applications that cannot resolve the host name of a node by binding to a local IP address might fail to function or behave in unexpected ways.

I think it was meant to go into the “System Requirements”, probably somewhere in this paragraph: https://docs.mesosphere.com/1.12/installing/production/system-requirements/#port-and-protocol-configuration

It’s related to bullet 3 in that list, I believe.
