Hi team!
I have a customer requesting this functionality as well (Bison Trails Co.)
Description
we want to take advantage of the recently introduced regional GKE clusters with HA hosted masters in three zones of a region.
This will allow us to avoid issues during master upgrades, in particular with horizontal pod autoscaling (this bit us in the past).
The current migration path is explicitly to create a new regional GKE cluster then migrate workloads from the zonal cluster:
> You can choose to create zonal or regional clusters at the time of cluster creation. However, you cannot migrate or downgrade a zonal cluster to a regional cluster, and vice versa.
cf.
This adds a lot of planning work to limit downtime during the migration from zonal to regional clusters.
The most obvious sensitive points in our use case being:
* How to migrate a GLB ingress with a static IP address from one cluster to another without disruption?
* How to make two clusters cohabit in the same subnet with a limited IP range (e.g. a /28 CIDR prefix, required for incoming traffic routed through a VPN with a partner)?
Can we expect a more straightforward path in the future where an existing zonal cluster can be converted to regional cluster without recreation and downtime?
Best regards,
Patrick.
