> Zookeeper quorum formation fails when TLS is enabled in k8s env
> ---------------------------------------------------------------
>
> Key: ZOOKEEPER-4536
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4536
> Project: ZooKeeper
> Issue Type: Bug
> Components: leaderElection, quorum
> Affects Versions: 3.7.0
> Environment: Kubernetes 1.21.1
> Reporter: Sai kiran
> Priority: Blocker
>
> We have three(3) node zookeeper cluster running as a pod on Kubernetes
> cluster, zookeeper quorum formation fails with TLS handshake error, as the
> server name in the https request does not match with any of the SANs in the
> certificate configured for zookeeper server. Server name in the request is of
> the form "x-x-x-x.kubernetes.default.svc.cluster.local" (where x-x-x-x is the
> IP address of the POD), and I am unable to understand the reason behind
> pre-pending FQDN with a IP address.
>
> Please find below the extract of the error logs from the zookeeper POD
