我配置了一个sidecar容器，用于收集应用程序容器的日志。
我首先使用以下配置测试了我的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kubectl跟踪我的pod中fluentd容器的日志时，它工作得很好，我可以看到JSON格式的应用程序日志。
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>
fluentd容器在我的pod中运行良好，但我无法定义我在Kibana的fluetn.conf中配置的索引。索引模式似乎没有加载到elasticsearch中。
fluentd容器显示以下警告：

如何摆脱此警告"[types removal] Specifying types in bulk requests is deprecated."？fluent.conf有什么额外的配置可以帮助我度过难关吗？
我尝试在配置中使用suppress_type_name true，但它不起作用。
仅在插件4.0.10版本中添加了对suppress_type_nametrue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，因此升级并设置配置中的标志应该可以消除警告。该警告不应影响批量请求。
