Until Docker learns parent mount namespace customization the container will
always have the root ns as a parent, not the one of the km minion. Hence, the
kubelet (which lives in the km minion mount ns) will create mounts that cannot
be seen by the Docker containers.
This feature can be enabled again when Docker learns to explicitly set the
parent mount ns, in analogy to the parent cgroup.
The minion server will
- launch the proxy and executor
- relaunch them when they terminate uncleanly
- logrotate their logs.
It is a replacement for a full-blown init process like s6 which is not necessary
in this case.
