Jie Yu created MESOS-2528:
-----------------------------
Summary: 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
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).
