Kapil Arya commented on MESOS-6396:
-----------------------------------

Just left a comment on the RR. Basically, wondering if we can create something similar to `ContainerPrepareInfo` (https://github.com/apache/mesos/blob/master/include/mesos/slave/containerizer.proto#L142) for Docker containers as well.

> The {{slaveExecutorEnvironmentDecorator}} hook is the only one that allows mutating the executor environment of a Docker container. That callback has no means of getting the location of the sandbox. That in turn means that it is not possible for a hook to create files and respective environment variables listing  paths within the sandbox for the executor to access.
