Gilbert Song commented on MESOS-7374:
-------------------------------------
[~anandmazumdar], yes, I added the targeted versions.
[~timcharper], thanks for reporting. I think it might be worth to add a check
in provisioner for filesystem/linux isolator if there is an image specified,
because we already document fs linux isolator is a MUST:
https://github.com/apache/mesos/blob/master/docs/container-image.md#configure-the-agent
I will reproduce the host mount issue first and then add a check once I have a
chance.

> Key: MESOS-7374
> URL: https://issues.apache.org/jira/browse/MESOS-7374
> Project: Mesos
> Issue Type: Bug
> Components: isolation
> Affects Versions: 1.2.0
> Reporter: Tim Harper
> Labels: containerizer, mesosphere
>
> If I run the pod below (using Marathon 1.4.2) against a mesos agent that has
> the flags (also below), then the overlay filesystem replaces the system root
> mount, effectively rendering the host unusable until reboot.
> flags:
> - {{--containerizers mesos,docker}}
> - {{--image_providers APPC,DOCKER}}
> - {{--isolation cgroups/cpu,cgroups/mem,docker/runtime}}
> pod definition for Marathon:
> {code:java}
> {
> "id": "/simplepod",
> "scaling": { "kind": "fixed", "instances": 1 },
> "containers": [
> {
> "name": "sleep1",
> "exec": { "command": { "shell": "sleep 1000" } },
> "resources": { "cpus": 0.1, "mem": 32 },
> "image": {
> "id": "alpine",
> "kind": "DOCKER"
> }
> }
> ],
> "networks": [ {"mode": "host"} ]
> }
> {code}
> Mesos should probably check for this and avoid replacing the system root
> mount point at startup or launch time.
