elasticsearch - 无法在 ubuntu 上的 kubernetes 集群中创建 fluentd 容器

问题描述

我正在尝试使用 Elasticsearch、Fluentd 和 Kibana 对我的 kubernetes 集群进行日志监控。这是我在此任务中关注的链接。我用 beta.kubernetes.io/fluentd-ds-ready: "true" 标记了节点。最初，我为 Elasticsearch 创建了 statefulset。

之后，我创建了 fluentd-es-configmap.yaml、fluentd-es-ds.yaml 并使用kubectl get pods -n kube-system. Fluentd pod 显示容器创建等状态。我检查了 Fluentd 容器的日志，它显示如下错误：

来自服务器的错误（BadRequest）：pod“fluentd-es-v2.0.1-csx96”中的容器“fluentd-es”正在等待启动：ContainerCreating

这是流利的 pod 描述：

有人可以建议我如何解决这个问题吗？
