我一直在尝试在单个节点中设置 ICP EE，但是一旦我开始部署监控服务任务，我就会一直安装失败。

此特定任务运行大约 30 分钟，然后失败。下面是我得到的错误日志。

我需要做些不同的事情吗？

为此，我使用了知识中心上的基本安装步骤。

这个节点至少有16G内存（甚至32G）吗？当 pod 上线时，主机可能被初始负载压得喘不过气来。

要测试的第二件事是应用此目录时会发生什么：

  • 您可以从命令行重新运行相同的操作： cd cluster/ kubectl apply --force --overwrite=true -f cfc-components/monitoring/

  • 然后你可以反省幕后发生的事情：

kubectl -n kube-system get pod -o wide

  1. pod 是否卡在非运行状态？
  2. pod 中的容器是否没有启动（例如显示 0/2 或 1/3 或类似）？

journalctl -ru kubelet -o cat | head -n 500 > kubelet-logs.txt

  1. kubelet 是否抱怨无法启动容器？

  2. kubelet 是否抱怨 Docker 不健康？

  3. 如果某个 pod 表明它不健康（高于 #1/#2），则对其进行描述并验证是否有任何事件表明它失败的原因：

kubectl -n kube-system describe pod [failing-pod-name]

如果你还没有kubectl在宿主机上配置和系统交互，或者auth-idpPod 还没有部署，你可以使用下面的步骤来配置kubectl：

  • 将 kubectl 二进制文件复制到主机上，然后使用本地 kubelet 配置。KUBECONFIG您可以在您的 shell 配置文件（例如）中更新该文件，.bash_profile使其适用于每个终端会话。

docker run -e LICENSE=accept -v /usr/local/bin:/data \ ibmcom/icp-inception:[YOUR_VERSION] \ cp /usr/local/bin/kubectl /data export KUBECONFIG=/var/lib/kubelet/kubelet-config
