Filebeat如何配置以支持容器文件的采集

Filebeat可以通过以下配置支持容器文件的采集，并通过add_kubernetes_metadata组件增加Kubernetes元信息：

yaml
    filebeat.yml: |- 
    filebeat.registry.flush: 30s 
    processors: 
    - add_kubernetes_metadata: 
    host: ${NODE_NAME} 
    matchers: 
    - logs_path: 
    logs_path: "/var/log/containers/" 
    - drop_event: 
    when: 
    equals: 
    input.type: container 
    output.console: 
    pretty: false 
    queue: 
    mem: 
    events: 4096 
    flush.min_events: 2048 
    flush.timeout: 1s 
    max_procs: 4 
    filebeat.inputs: 
    - type: container 
    harvester_buffer_size: 524288 
    paths: 
    - /var/log/containers/nginx-log-demo-0-*.log
