Fluentd sidecar isn't able to send logs to Elasticsearch: types removal Specifying types in bulk requests is deprecated

I have a sidecar container configured to collect logs for my app container.

I first tested my fleunt.conf using the following configuration:

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

It worked fine when I tailed the log of fluentd container in my pod using kubectl, I could see my app logs in JSON format.

Now, I am trying to send the logs to elasticsearch. Here is my fluent.conf for the same:

<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>

The fluentd container is running fine inside my pod but I am not able to define the index that I have configured in fluetn.conf in Kibana. Looks like the index pattern is not getting loaded into elasticsearch.

The fluentd container is showing the following warning:

How do I get rid of this warning "[types removal] Specifying types in bulk requests is deprecated."? Is there any additional configuration to the fluent.conf that can help me get past this?

I tried using suppress_type_name true in the configuration but it did not work.

Support for suppress_type_name true was only added with version 4.0.10 of the plugin: https://github.com/uken/fluent-plugin-elasticsearch/blob/master/History.md#4010.

According to the logs, you're running 4.0.0, so upgrading and setting the flag in the config should get rid of the warning. The warning should not affect the bulk request.
