Description Suresh Kolichala 2020-04-08 18:22:46 UTC 
+++ This bug was initially created as a clone of Bug #1822326 +++

Description of problem:

The fix for Bug 1817028 (https://bugzilla.redhat.com/show_bug.cgi?id=1817028) introduced a new init container to validate the etcd environment before firing up the etcd. However, the checks for ensuring the etcd environment rely on ipstring comparison which fails in the ipv6 environments. 

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


How reproducible:
Always

Steps to Reproduce:
1. Create a ipv6 cluster

Actual results:
The etcd members fails to start with the init container failing forever with an error similar to:
Expected node IP to be fd2e:6f44:5dd8:c956::15 got [fd2e:6f44:5dd8:c956::15]

Expected results:
etcd to come up normally, and the cluster to become available.

Tried etcd on ipv6 virt cluster with 4.4 2 weeks ago,it works well, and we have not ipv6 env to double it now, so close this bug.
