Kubernetes 如何使用fluentd将纯文本格式的日志推送到AWS cloudwatch？

我想以纯文本格式将Kubernetes吊舱中的日志发送到cloudwatch。有没有办法做到这一点

我能够使用fluent/fluentd-kubernetes守护程序以JSON格式发送日志：v1.3.3-debian-cloudwatch-1.0，但我不确定如何以纯文本格式发送。我真的很感激任何帮助

当前日志：

{
  "log": "2020-04-22 08:00:00.002  WARN 7 --- [viderScheduler1] c.o.c.a.p.c.SchedulerConfiguration       :  HELLO\n",
  "stream": "stdout",
  "docker": {
    "container_id": "ASDF"
  },
  "kubernetes": {
    "container_name": "CHART",
    "namespace_name": "NAMESPACE",
    "pod_name": "POD_NAME",
    "container_image": "IMAGE",
    "container_image_id": "IMAGE_ID",
    "pod_id": "ID",
    "labels": {

    },
    "host": "IP",
    "master_url": "master_URL",
    "namespace_id": "ns"
  }
}

预期日志：
