I have a ELK stack with Filebeat as an agent. Works great for collecting logs of existing pods.
Here is the helm values for filebeat
filebeatConfig:
  filebeat.yml: |
    logging.level: error
    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
            
    output.logstash:
      hosts: 'logstash-logstash.logging.svc.cluster.local:5044'
    setup.template:
      name: "k8s"
      pattern: "k8s-*"
      enabled: false
    setup.ilm.enabled: false
Now, I have a new Kubernetes deployment of falco , whose logs are in json format and want to ship it to ELK stack but not able to with this config. How can I possibly do it, not able to figure out the right way.
Tried following that didn't work
            type: container
            paths:
              - /var/log/containers/*${data.kubernetes.container.id}.log
             json.keys_under_root: true
             json.add_error_key: true
             json.message_key: message
