Filebeat red status after quickstart deployment

Good morning.

After creating the operator and deploying 3 Master nodes + 3 multi-role nodes of ES with the following manifest:

cat <<EOF | oc apply -f -
apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: elkcluster
spec:
  version: 8.2.3
  nodeSets:
  - name: masters
    config:
      node.roles: ["master"]
      node.store.allow_mmap: false
    count: 3
  - name: data
    count: 3
    config:
      node.roles: ["data", "ingest", "ml", "transform"]
EOF

And after deploying Kibana with this other manifest:

cat <<EOF | oc apply -f -
apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
metadata:
  name: kibana
spec:
  version: 8.2.3
  count: 2
  elasticsearchRef:
    name: elkcluster
EOF

Which seems to work well:

$ oc get all

I tried to deploy beats by using the 'quick start' manifest.
https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-beat-quickstart.html
But I know I did some changes as I added extra ES nodes with different roles and one extra Kibana pod in my previous manifests.

This is the manifest I should use but when I use it, it doesn't work.

 cat <<EOF | kubectl apply -f -
 apiVersion: beat.k8s.elastic.co/v1beta1
 kind: Beat
 metadata:
   name: quickstart
 spec:
   type: filebeat
   version: 8.2.3
   elasticsearchRef:
     name: quickstart
   config:
     filebeat.inputs:
     - type: container
       paths:
       - /var/log/containers/*.log
   daemonSet:
     podTemplate:
       spec:
         dnsPolicy: ClusterFirstWithHostNet
         hostNetwork: true
         securityContext:
           runAsUser: 0
         containers:
         - name: filebeat
           volumeMounts:
           - name: varlogcontainers
             mountPath: /var/log/containers
           - name: varlogpods
             mountPath: /var/log/pods
           - name: varlibdockercontainers
             mountPath: /var/lib/docker/containers
         volumes:
         - name: varlogcontainers
           hostPath:
             path: /var/log/containers
         - name: varlogpods
           hostPath:
             path: /var/log/pods
         - name: varlibdockercontainers
           hostPath:
             path: /var/lib/docker/containers
 EOF

Once I use it the beat service is in red status forever.

Can someone please tell me what changes should I made to make it work? I'm sorry of my lack of knowledge in K8's.

Thank you very much to all and regards.
