我已经在kubernetes中设置了filebeat作为守护进程，将日志从Docker容器转发到ES + kibana（通过引用https://www.elastic.co/guide/en/beats/filebeat/master/running-on-kubernetes.html），日志转发成功。
问题是当存在多行日志时，它们作为单独的日志行转发到ES。
这里是我配置多行过滤器的地方我的filebeat-kuberneted.yaml

---
apiVersion: v1
kind: ConfigMap
metadata:
  name: filebeat-prospectors
  namespace: kube-system
  labels:
    k8s-app: filebeat
    kubernetes.io/cluster-service: "true"
data:
  kubernetes.yml: |-
    - type: docker
      containers.ids:
      - "${data.kubernetes.container.id}"
      processors:
        - add_kubernetes_metadata:
            in_cluster: true
      multiline:
        pattern: '^[[:space:]]'
        negate: false
        match: after

但是我可以在没有kubernetes的docker上成功地应用filebeat多行过滤器，也可以在非docker部署上应用filebeat多行过滤器，所以我猜问题出在我的filebeat-kuberneted.yaml配置文件上。
我在我的fileat-kuberneted.yaml配置中丢失了一些东西吗？
