It'd be very useful to run docker-in-docker for example. And exposing the feature as a simple JSON attribute should be pretty easy.

I need to mount HDFS or whatever in docker container.

@PAStheLoD could you please show more information with you. don't know why reason need run privileged docker.

We're running a patched version of Chronos (--privileged hacked in), to build docker images.

Basically, we use docker-in-docker to build and push to a private registry (running on Marathon/Mesos too), and then start the freshly built container as a Marathon service.

+1 We run a docker container that is building a database in a docker container who needs to be pushed to a private registry. We need to mount inside the container a directory.

+1 docker in docker is also what I need. Any news on this?

Update:

I think this works:

"parameters": [
                {"key": "privileged", "value": "true"}
            ],

Another use case is to run batches on gpu slaves... So basically the jo is not executed since mesos requires privileged mode to use those slaves.

I could use this.

It should be possible to add a privileged field to the job definition and to Chronos' TaskInfo builder set ContainerInfo.privileged based on that.

I don't have time to implement this change myself, but if someone wants to volunteer, I could review and merge the PRs.

Actually, privileged is no longer good anyway. We no longer run tasks on gpu with privileged mode. But a gpu parameter would be a good addition. More basically, we should simply be able to put a marathon json (gpu, constraints, mesos containerizer options...)

Yeah, finer grain control is needed for leveraging things like RexRay etc..
