elasticsearch - Fluentd Sidecar无法将日志发送到Elasticsearch:类型删除已弃用在批量请求中指定类型

Question

我有一个sidecar容器，配置为收集我的应用程序容器的日志。
我首先使用以下配置测试了fleunt.conf:

<source>
    @type forward
    bind "127.0.0.1"
    port 24224
    <parse>
      @type json
    </parse>
  </source>
  <match app.default>
    @type stdout
  </match>

当我使用fluentd将kubectl容器的日志拖到我的pod中时，它工作正常，我可以看到我的应用程序日志为JSON格式。
现在，我正在尝试将日志发送到elasticsearch。这是我的fluent.conf:

<source>
    @type forward
    bind "127.0.0.1"
    port 24224
    <parse>
      @type json
    </parse>
  </source>
  <match app.default>
    @type elasticsearch
    host "elasticsearch_host"
    port 9200
    index_name "app-log"
    user "log_user"
    password xxxxxx
  </match>

流利的容器在pod内运行良好，但无法定义在Kibana的fluetn.conf中配置的索引。看起来索引模式没有加载到elasticsearch中。fluentd容器显示以下警告:

我如何摆脱这个警告"[types removal] Specifying types in bulk requests is deprecated."？ fluent.conf是否有任何其他配置可以帮助我克服这一点？
我尝试在配置中使用suppress_type_name true，但没有用。

仅在插件的版本4.0.10中添加了对suppress_type_name true的支持:https://github.com/uken/fluent-plugin-elasticsearch/blob/master/History.md#4010。
根据日志，您正在运行4.0.0，因此在配置中升级和设置标志应摆脱警告。该警告不应影响批量请求。
