amazon-web-services - 无法让 ArgoCD 在运行 centos 7 的 EC2 上工作

问题描述

我正在尝试按照AWS的官方文档和EKS 研讨会argocd在我的 EC2 实例上运行，但它处于挂起状态，命名空间中的所有 pod 都运行良好。centos 7kube-system

下面是输出kubectl get pods --all-namespaces

docker虽然相同的配置在我的本地 Mac 上运行良好，但我已确保kubernetes服务已启动并正在运行。尝试删除 pod，重新配置 argocd，但每次结果都保持不变。

作为新手，ArgoCD我无法弄清楚同样的原因。请让我知道我哪里出错了。谢谢！

解决方案

我通过运行找出了问题所在：

kubectl describe pods <name>  -n argocd

它给出了以 FailedScheduling 结尾的输出：

...
Events:
  Type     Reason            Age                From               Message
  ----     ------            ----               ----               -------
  Warning  FailedScheduling  3m (x5 over 7m2s)  default-scheduler  0/1 nodes are available: 1 node(s) had taint {node-role.kubernetes.io/master: }, that the pod didn't tolerate.

此后，通过参考这个 GitHub 问题，我想出了运行：

kubectl taint nodes --all node-role.kubernetes.io/master-

执行此命令后，Pod 开始工作并从Pending状态转换为Running，kubectl describe pods输出显示为：

...
Events:
  Type     Reason            Age                From               Message

  Normal   Started           72s                kubelet            Started container argocd-server

从这个错误和解决方案中，我学会了始终使用kubectl describe pods来解决错误。
