fluidd 错误“Systemd::JournalError: 没有这样的文件或目录”

Question

我确实在我的 kube 工作人员上安装了Fluentd-kubernetes-daemonset，其中一个工作没有任何错误，但另一个则抛出以下错误：

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

如果您没有在容器中设置 systemd， fluidd 默认配置会显示以下消息。

[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

您可以通过在 kubernetes 配置中设置环境变量来抑制这些消息，例如disable：FLUENTD_SYSTEMD_CONF

      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'
