Background:
I’m following a guide to configure Filebeat in Kubernetes for parsing JSON logs. The guide suggests using autodiscover to detect and configure the inputs automatically.

Guide: https://www.elastic.co/guide/en/beats/filebeat/current/running-on-kubernetes.html#_parsing_json_logs

I’m encountering an error with Filebeat while trying to configure it in a Kubernetes environment to parse JSON logs. The error message I’m seeing is:

"Exiting: no modules or inputs enabled and configuration reloading disabled. What files do you want me to watch?"

Configuration:
Here’s the relevant part of my Filebeat ConfigMap:

apiVersion: v1
kind: ConfigMap
metadata:
  name: filebeat-config
  namespace: kube-system
  labels:
    k8s-app: filebeat
data:
  filebeat.yml: |-
    filebeat.autodiscover:
    providers:
      - type: kubernetes
        node: ${NODE_NAME}
        hints.enabled: true
        hints.default_config:
          type: container
          paths:
            - /var/log/containers/*${data.kubernetes.container.id}.log

processors:
  - add_cloud_metadata:
  - add_host_metadata:

setup.template.name: "aks-pre"
setup.template.pattern: "aks-pre-*"

output.elasticsearch:
  hosts: ['${ELASTICSEARCH_HOST:elasticsearch}:${ELASTICSEARCH_PORT:9200}']
  username: ${ELASTICSEARCH_USERNAME}
  password: ${ELASTICSEARCH_PASSWORD}
  index: aks-pre

Any insights or suggestions would be greatly appreciated.

Thanks in advance!
