Kubernetes pod 在终止容器时由于“权限被拒绝”错误而陷入终止状态

Question

我正在尝试终止 Kubernetes 集群中的一个 pod，但它已经卡在“终止”状态好几天了。以下是日志的相关部分：

Warning  FailedKillPod  kubelet error killing pod: 
[failed to "KillContainer" for "insta-container" with KillContainerError: 
"rpc error: code = Unknown desc = failed to kill container \"5c56f2bfeb47b5491552c791b3f1d7a219b35efc35a568d26c0a2c908dbcecda\": 
unknown error after kill: runc did not terminate successfully: exit status 1: 
unable to signal init: permission denied\n: unknown", failed to "KillPodSandbox" 
with KillPodSandboxError: 
"rpc error: code = Unknown desc = failed to stop container \"5c56f2bfeb47b5491552c791b3f1d7a219b35efc35a568d26c0a2c908dbcecda\": 
failed to kill container: unknown error after kill: runc did not terminate successfully: 
exit status 1: unable to signal init: permission denied\n: unknown"]

以下是我采取的步骤：

1. 我创建了一个运行 ubuntu-24.04 的简单节点。
2. 当我尝试终止 Pod 时，它被卡住，并且日志中反复出现权限被拒绝的错误。

环境详情：

• Kubernetes 版本：v1.28.14
• 容器运行时：Docker
• 操作系统：Ubuntu 24.04

有没有人遇到过类似的问题，或者有人可以指导我如何解决这个问题吗？

试试这个

kubectl delete pod pod-name --grace-period=0 --force --namespace default

或者对于所有 Pod，都陷入“终止”状态

for i in $kubectl get po -n kube-system| grep konnec| awk '{print $1}'); do kubectl delete pod $i --grace-period=0 --force --namespace kube-system; done
