Cody Maloney commented on MESOS-2830:
-------------------------------------
Master HTTP endpoint would be a useful version.
Most the cases I can think of where we want / need to go straight to the slave
involve "mesos is down" at which point the endpoint wouldn't be of much use.
For `container` ideally I want to be able to grab arbitrary stuff / execution
environment to the host. Sometimes I'm going to want to run a full docker
container and volume mount /etc/passwd into it, other times I'll quite likely
be happy just running a process with no container isolation whatsoever.
Probably optimize for the "no container" case, although if I could launch
arbitrary mesos containers, that would be nice.
The baseline use case as SSHing to every slave is definitely the core one to
cover. Other common actions I'd expect are "remove a directory on specific
slaves", "do something on slaves which ran tasks for a framework", and "run a
command where a task ran".
Ideally either I can run things as a one-off "do it now", or ask mesos to
schedule it across a group of machines within a time frame (At which point
mesos could use things like maintenance primitives to cleanly get resources for
the jobs).

> As a System Administrator often times I need to run a organization-mandated
> task on every machine in the cluster. Ideally I could do this within the
> framework of mesos resources if it is a "cleanup" or auditing task, but
> sometimes I just have to run something, and run it now, regardless if a
> machine has un-accounted resources (Ex: Adding/removing a user).
> Currently to do this I have to completely bypass Mesos and SSH to the box.
> Ideally I could tell a mesos slave (With proper authentication) to run a
> container with the limited special permissions needed to get the task done.
