Benjamin Mahler commented on MESOS-2902:
----------------------------------------
Any reason that the mesos itself has to execute the script? It seems like the
start script for mesos should run the arbitrary code / external programs
necessary to compute flags. Taking this to its extreme, should we add scripts
for all of the flags (e.g. {{--resources}}, {{--quiet}}, etc)?
> Enable Mesos to use arbitrary script / module to figure out IP, HOSTNAME

> Key: MESOS-2902
> URL: https://issues.apache.org/jira/browse/MESOS-2902
> Project: Mesos
> Issue Type: Improvement
> Components: master, modules, slave
> Reporter: Cody Maloney
> Priority: Minor
> Labels: mesosphere
>
> Currently Mesos tries to guess the IP, HOSTNAME by doing a reverse DNS
> lookup. This doesn't work on a lot of clouds as we want things like public
> IPs (which aren't the default DNS), there aren't FQDN names (Azure), or the
> correct way to figure it out is to call some cloud-specific endpoint.
> If Mesos / Libprocess could load a mesos-module (Or run a script) which is
> provided per-cloud, we can figure out perfectly the IP / Hostname for the
> given environment. It also means we can ship one identical set of files to
> all hosts in a given provider which doesn't happen to have the DNS scheme +
> hostnames that libprocess/Mesos expects. Currently we have to generate
> host-specific config files which Mesos uses to guess.
> The host-specific files break / fall apart if machines change IP / hostname
> without being reinstalled.
