Version-Release number of selected component (if applicable):
4.14.0-0.nightly-2023-08-28-154013
How reproducible:
Intermittent (DHCPv6 related)
Steps to Reproduce:
1. install vsphere dual-stack IPI with DHCPv6
networking:
clusterNetwork:
- cidr: 10.128.0.0/14
hostPrefix: 23
- cidr: fd65:10:128::/56
hostPrefix: 64
machineNetwork:
- cidr: 192.168.0.0/16
- cidr: fd65:a1a8:60ad:271c::/64
networkType: OVNKubernetes
Actual results:
Masters missing IPv6 address in KUBELET_NODE_IPS
Install fails with
time="2023-08-30T19:54:19Z" level=error msg="failed to initialize the cluster: Cluster operators authentication, console, ingress, monitoring are not available"
Expected results:
Both IPv4 and IPv6 address in KUBELET_NODE_IPS
Install succeeds
Additional info:
Do we set ipv6.may-fail with NetworkManager?
