Description Jan Safranek 2020-09-16 08:47:14 UTC 
OCP AWS EBS and oVirt CSI drivers use "hostNetwork: true" and at the same time they use port 9808 for their liveness probes. Since range 9000 - 9999 is required to be accessible "All machines to all machines" in our docs [1], the liveness probe is accessible from all machines, which is not really wanted. Liveness probe should be accessible from the host only.
