Specific nodeAffinity to only primary

[bastoune]

Hello,

Hi would like to update the Kubegres statefulSet, but only the primary one.
Is it possible from the kubegres.reactive-tech.io/v1 resource ?

Basically, i would like to apply this spec:

      affinity:
        nodeAffinity:
          preferredDuringSchedulingIgnoredDuringExecution:
          - weight: 1
            preference:
              matchExpressions:
              - key: k8s.scaleway.com/dedicated-cpu
                operator: In
                values:
                - "true"

I want to keep the fact the replicats are in PodAntiAffinity with the Primary. But i want the primary to prefer being deployed on the k8s.scaleway.com/dedicated-cpu labelled node.

Thank you for your message.

This feature is not available in Kubegres.

It is a good idea and it could be implemented.

We are very low in dev resources at the moment, if you manage to implement it I can approve the PR.
