<p>I did install <strong>fluentd-kubernetes-daemonset</strong> on my kube workers on one did work without any error but on the other is throwing the following errors:</p>

<pre><code>2018-12-07 03:48:33 +0000 [warn]: #0 [in_systemd_bootkube] Systemd::JournalError: No such file or directory retrying in 1s

<p>If you don't setup systemd in the container, fluentd shows following messages by default configuration.</p>

<pre><code>[warn]: #0 [in_systemd_bootkube] Systemd::JournalError: No such file or directory retrying in 1s
[warn]: #0 [in_systemd_kubelet] Systemd::JournalError: No such file or directory retrying in 1s
[warn]: #0 [in_systemd_docker] Systemd::JournalError: No such file or directory retrying in 1s
</code></pre>

<p>You can suppress these messages by setting <code>disable</code> to <code>FLUENTD_SYSTEMD_CONF</code> environment variable in your kubernetes configuration, e.g.:</p>

<pre><code>      containers:
        - name: fluentd
          image: fluent/fluentd-kubernetes-daemonset:v1-debian-elasticsearch
          env:
            - name: FLUENT_ELASTICSEARCH_HOST
              value: 'elasticsearch'
            - name: FLUENT_ELASTICSEARCH_PORT
              value: '9200'
            - name: FLUENT_ELASTICSEARCH_SCHEME
              value: 'http'
            - name: FLUENT_UID
              value: '0'
            - name: FLUENTD_SYSTEMD_CONF
              value: 'disable'
</code></pre>
