Ah, I've been on 1.19 for a while so I'm definitely behind. I'm using GKE regional clusters and as such cannot do zero downtime upgrades to the control plane (they break DNS) so it's risky upgrading.
- dilyevsky 4y agoHm the topology-aware provisioning should be fixed since at least 1.12/13 and is working well on our self-managed regional clusters. I'd bug GKE support for this... Just curious - how does GKE control plane upgrade break DNS?
- powerhour 4y agoI don't have access to GKE support, unfortunately, so the best I can do is submit product feedback. The cluster's DNS server refuses connections briefly during control plane upgrades or updates. I haven't tried their node local DNS yet (enabling it will cause downtime, natch), maybe it'd help.
