Subject [jira] [Commented] (MESOS-7476) Restrict capabilities to only the bounding set.
Date Thu, 18 May 2017 22:39:04 GMT


James Peach commented on MESOS-7476:

As per discussion with [~jieyu], what we should do here is introduce a new flag {{--bounding_capabilities}}
that manipulates only the bounding capabilities.

* The bounding capability set must be equal or greater than the granted capability set.
* If the capabilities granted in TaskInfo exceed the configured bounding set, the isolator
should fail the task.
* If the {{\-\-bounding_capabilities}} option is not a superset of the {{--allowed_capabilities}}
option, the agent should fail to start.

> As a security improvement, it would be useful to be able to set the bounding capability
set without also granting those capabilities. This is what the {{--allowed_capabilities}}
flag sounds like it does.
