ECK where to put elasticsearch.yaml settings

Is this not the correct place for configuration within Helm? I'm still seeing the default settings when doing a GET /_cluster/settings?include_defaults such as auto_create_index: true and disk.watermark.low: 85% ...

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: clusterino
  namespace: {{ .Release.Namespace }}
  # Mark for Metrics beat to scrape
  labels:
    scrape: {{ .Release.Namespace }}-es
spec:
  version: {{ .Values.es_version }}
  nodeSets:
    - name: masters
      count: 3
      config:
        action.auto_create_index: ".security,.monitoring*,.watches,.triggered_watches,.watcher-history-*,.ml*,filebeat-*"
        cluster.routing.allocation.node_initial_primaries_recoveries: 4
        cluster.routing.allocation.node_concurrent_recoveries: 2
        cluster.routing.allocation.disk.threshold_enabled: true
        cluster.routing.allocation.disk.watermark.low: "88%"
        cluster.routing.allocation.disk.watermark.high: "90%"
        cluster.routing.allocation.disk.watermark.flood_stage: "95%"
        indices.memory.index_buffer_size: "30%"
        indices.breaker.total.use_real_memory: false
        node.roles: ["master"]
        xpack.ml.enabled: false

Hi,

The settings in the config section must be applied to all the nodes, did you set them in all the nodeSets?
