remove resource requests for initContainer in Kafka StatefulSet

[hari819]

Hello Team,

i would like to remove the resources section by adding empty {} in the kafka STS section for the initContainer , because sometimes PODs are unable to start with insufficient cpu error , I was able to do this for the main Kafka container using

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
name: kafka
spec:
kafka:
  version: 2.7.0
  replicas: 3
  template:
    pod:
      resources: {} #disable requests

but i am unable to set the same for the initContainer ,

initContainers:
  - name: kafka-init
    image: 'quay.io/strimzi/operator:0.22.1'
    args:
      - /opt/strimzi/bin/kafka_init_run.sh
    resources:
      limits:
        cpu: '1'
        memory: 256Mi
      requests:
        cpu: 100m
        memory: 128Mi

could you please help me on this ,

We currently do not support configuring the resources for the init container. The resource are hardcoded. In general, I'm not sure how will will your Kafka cluster work if you do not have these resources available in your cluster - Kafka is in general fairly hungry for resources. But I think the request to make them configurable is not unreasonable. So we can have a look into it. Can you open a bug or enhancement issue for it please?
