我正试图按照AWS的官方文档和EKS研讨会，在运行centos 7的EC2实例上运行argocd，但它处于挂起状态，kube-system命名空间中的所有pod都运行良好。
以下是kubectl get pods --all-namespaces的输出
NAMESPACE NAME READY STATUS RESTARTS AGE

虽然相同的配置在我的本地mac上运行良好，但我已经确保docker、kubernetes服务已经启动并运行。尝试删除pod，重新配置argocd，但每次结果都保持不变。
作为ArgoCD的新手，我无法找出同样的原因。请告诉我哪里出了问题。谢谢
我通过运行发现了问题所在
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.
从此以后，通过引用这个GitHub问题，我发现要运行：
kubectl taint nodes --all node-role.kubernetes.io/master-
在该命令之后，pod开始工作，并从Pending状态转换为Running，kubectl describe pods的输出显示为：
...
Events:

---- ------ ---- ---- -------

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。
