@Greg_Day: Hello, I am looking for some guidance on the proper ways to apply configurations after provisioning a ScyllaCluster manifest via scylla-operator. If I want to add or remove racks, do I simply need to reconfigure the manifest and scylla-operator will handle it? Also is there a recommended way to change immutable fields, like exposeOptions, or does that require a complete re-provisioning?
additionally, I do not see a way to use preallocated IP addresses for GKE internal loadbalancers:
exposeOptions:
broadcastOptions:
clients:
type: ServiceLoadBalancerIngress
nodeService:
annotations:
<http://networking.gke.io/load-balancer-type|networking.gke.io/load-balancer-type>: Internal
type: LoadBalancer
I tried using the <http://kubernetes.io/ingress.regional-static-ip-name|kubernetes.io/ingress.regional-static-ip-name> annotation on the CRD, but it turns out this is wrong and does not apply to internal passthrough loadbalancers, only Ingresses.

Simply change ScyllaCluster spec and scylla-operator will take care of reconciling it.

Immutable fields are immutable. You have to recreate the cluster. If you don’t delete PVC’s (they survive ScyllaCluster deletion), you won’t loose any data, there will be a downtime though.

Annotation you mentioned only works on Ingresses. To expose ScyllaCluster via Ingress there’s exposeOptions.cql.ingress but it requires SNI proxy.
Seems like we are missing a field to support preallocated LB address. You may submit a feature request in scylla-operator repo.
@Greg_Day: > Immutable fields are immutable.
yes, sorry for the confusing language, I was just looking for tips on that recreation process, but I can handle that no problem.

sounds good, I might even take a look and see if I could add it and submit a PR
