Subject Re: how does resource allocation work with docker?
Date Wed, 23 Sep 2015 13:41:56 GMT
Hi Clarke,

You can take a look at the framework for docker here
https://github.com/apache/mesos/blob/master/src/examples/docker_no_executor_framework.cpp

All of the resource limitations for a docker task should be defined in the
framework.

Thanks,

Guangya
