      Previously, an IPv6 configuration for Red Hat build of MicroShift was created in the system at first start when an IP address was not configured. This was caused by an erroneous retrieval of the default node IP address because of order in which the interfaces were listed. This misconfiguration of the default IP address could result in the service being unreachable. With this release, the correct node IP address is retrieved first.

      Description of problem:

      MicroShift is left to default configuration for node ip, service and cluster networks. This is also a disconnected environment, hence no default routes are configured in the host because there is no need.
When starting or showing configuration (with microshift show-config), an ipv6 configuration can be seen for the values mentioned above.

      Version-Release number of selected component (if applicable):

      4.17.3

      How reproducible:

      Steps to Reproduce:

      Actual results:

      MicroShift gets configured with ipv6 addresses.

      Expected results:

      MicroShift should get configured with ipv4 addresses.
