Hi all! I've got an RKE2 cluster set up, and I've added a remote cluster in Azure for it to manage. We occasionally get this error when doing a kubectl apply -f on it:
error trying to reach service: dial tcp: lookup [HOSTNAME] on [COREDNS:53] no such host
. We've been able to isolate the issue to CoreDNS, and specifically one of the CoreDNS pods seems to be unable to resolve the lookup being requested...but this works a few seconds later (on the same pod). Has anybody experienced this, or does anybody have some advice/guidance on how we might fix it?
