Kubernetes ReplicaFailure FailedCreate 但没有事件

Question

我在 Kubernetes 中有部署和副本集，但无法创建 pod。我试过了kubectl describe deployment deployment-name和kubectl describe replicaset replicaset-name他们都说

Conditions:
  Type             Status  Reason
  ----             ------  ------
  ReplicaFailure   True    FailedCreate
Events:            <none>

我见过的所有故障排除指南都依赖于来自事件部分的信息，但它说 <none>就我而言。如何获得更多信息来调试问题？

Answer 1

描述副本集将为您提供导致部署对象失败的错误。

./kubectl describe replicaset <replica-set-name>

示例错误:
