> As part of the overall design doc for global resources we would like to introduce improvements for Docker Volume Driver isolator module (https://github.com/emccode/mesos-module-dvdi).
> Currently the isolator module is controlled by setting environment variables as follows: {code} "env": {
>   "DVDI_VOLUME_NAME": "testing",
>   "DVDI_VOLUME_DRIVER": "platform1",
>   "DVDI_VOLUME_OPTS": "size=5,iops=150,volumetype=io1,newfstype=ext4,overwritefs=false",
>   "DVDI_VOLUME_NAME1": "testing2",
>   "DVDI_VOLUME_DRIVER1": "platform2",
>   "DVDI_VOLUME_OPTS1": "size=6,volumetype=gp2,newfstype=xfs,overwritefs=true"
> } {code} We should develop a more structured way for passing these settings to the isolator module which is in line with the overall goal of global resources.
