Dear community,

I’m trying to setup CPV 2021.1.0 on an ESXi host via OVA (Single Node).
After applying the mandarotry information and hitting (a)pply the process starts but quickly comes to halt at “still waiting for coredns clickhouse dispatcher […] … (total 146)”. This goes on for hours and is reproducible.
Does it mean, something is wrong with DNS (which I didn’t configure, as its optional) or does the order of services not indicate what’s currently processed?
Is this some known behavior anybody has a fix for?

I’m currently downloading the 2020.3 release to check if that works…

Thank you and kind regards,
Nik

Hi Nik,

Prior to 2021.1.0 on single node instances configuring a DNS server was optional, however with 2021.1.0 even though from cvpi perspective this would work, coreDNS (the DNS service used by k8s) with the latest update requires at least 1 IP in /etc/resolv.conf (this can be a dummy IP too), so if you configure any IP there components should start up. This was an escape and future releases should make the DNS field mandatory.

HTH,

Tamas
