Container network issue with 2.89.15 and cp-zookeeper/Redhat ubi8 containers

Another update, I was also able to ping all services from all other services after switching from ubi-minimal to ubi. Perhaps it’s a feature of the minimal base image?

@cywang117 Thank you for your investigation. However it is not related to the base image. As I wrote above I can reproduce it only with balenalib/intel-nuc-ubuntu:bionic. If you try to ping test3_long_name from test1 or test2. To remove the confusion I pushed the following docker-compose. However atm something is stuck at the device and its not updating, although the target release is correct (that might be a separate issue)

version: "2.1"

services:
  test1:
    image: balenalib/intel-nuc-ubuntu:bionic
    entrypoint: ["tail", "-f", "/dev/null"]
  test2:
    image: balenalib/intel-nuc-ubuntu:bionic
    entrypoint: ["tail", "-f", "/dev/null"]
  test3_long_name:
    image: balenalib/intel-nuc-ubuntu:bionic
    entrypoint: ["tail", "-f", "/dev/null"]

Therefore I think it’d be good to reopen the issue.
