Jie Yu updated MESOS-2528:
--------------------------
Labels: twitter (was: )
> Symlink the namespace handle with ContainerID for the port mapping isolator.
> ----------------------------------------------------------------------------
>
> Key: MESOS-2528
> URL: https://issues.apache.org/jira/browse/MESOS-2528
> Project: Mesos
> Issue Type: Improvement
> Reporter: Jie Yu
> Assignee: Jie Yu
> Labels: twitter
>
> This serves two purposes:
> 1) Allows us to enter the network namespace using container ID (instead of
> pid): "ip netns exec <ContainerID> [commands] [args]".
> 2) Allows us to get container ID for orphan containers during recovery. This
> will be helpful for solving MESOS-2367.
> The challenge here is to solve it in a backward compatible way. I propose to
> create symlinks under /var/run/netns. For example:
> /var/run/netns/containeridxxxx --> /var/run/netns/12345
> (12345 is the pid)
> The old code will only remove the bind mounts and leave the symlinks, which I
> think is fine since containerid is globally unique (uuid).
