Enable Isolator to work with other Isolators #89

Closed clintkitson closed 8 years ago

clintkitson commented 8 years ago

The current module at version 0.1 is limiting due to the Isolator implementation. Currently, there is only one type of filesystem based Isolator that can be used at a time. This means that if you are using the mesos-module-dvdi you cannot isolator the filesystem to a single container, it must be exposed to all containers.

The problem is due to the fact that Isolators don't pass mount points between themselves. The mount point is only determined after mesos-module-dvdi runs which then needs to be passed to the next Isolator to privately mount the filesystem in the container.

The plan as discussed is to create a library that abstracts the mesos containerizer. This way the mesos-module-dvdi can call other isolators on it's own.

In the future, a proper order of events for prepare(), cleanup() etc would likely be desirable to containerizers that call each other.
