<p>I've installed fluentd in my AKS cluster using the following command <code>helm install fluentd bitnami-azure/fluentd --namespace mynamespace --set forwarder.configMap=fluentd-aksconfig</code>. </p>

<p>Below is my configmap.yaml</p>

<pre><code>apiVersion: v1
kind: ConfigMap
metadata:
  name: fluentd-aksconfig
  namespace: mynamespace
data:
  fluentd.conf: |
    &lt;match **&gt;
          @type azure-storage-append-blob
          azure_storage_account    mystorageaccount
          azure_storage_access_key myaccesskey
          azure_container          aksfluentd
          auto_create_container    true
          path logs/
          azure_object_key_format  %{path}%{time_slice}_%{index}.log
          time_slice_format        %Y%m%d-%H
          # if you want to use %{tag} or %Y/%m/%d/ like syntax in path / azure_blob_name_format,
          # need to specify tag for %{tag} and time for %Y/%m/%d in &lt;buffer&gt; argument.
          &lt;buffer tag,time&gt;
            @type file
            path /var/log/fluent/azurestorageappendblob
            timekey 120 # 2 minutes
            timekey_wait 60
            timekey_use_utc true # use utc
          &lt;/buffer&gt;
    &lt;/match&gt; 
</code></pre>

<p>below are the errors obtained from the pods. It displays that there is no plugin called "azure-storage-append-blob". How to fix this?</p>

<p><a href="https://github.com/microsoft/fluent-plugin-azure-storage-append-blob" rel="nofollow noreferrer">azure-storage-append-blob</a> plugin is not installed by default. So you need to install it. Docs on how to install Fluentd plugin is <a href="https://docs.fluentd.org/v/0.12/deployment/plugin-management" rel="nofollow noreferrer">here</a>.</p>
