我对 Kubernetes 还很陌生，我遇到了这个问题，pod 不断重新启动。我在 Google 上搜索了一下，但没有找到太多帮助。我只有一个简单的 Apache 部署，没有什么特别的。
apiVersion: apps/v1
kind: Deployment
metadata:
name: website-deployment
labels:
app: website
spec:
replicas: 2
selector:
matchLabels:
app: website
template:

app: website
spec:
containers:
- name: apache
image: httpd:2.4.57
ports:
- containerPort: 80
这是来自 pod 的日志
root@kubemaster:~# kubectl logs website-deployment-cc57f5644-2kg7v -p

如您所见，它运行了几分钟，然后收到 SIGWINCH 事件，这会触发 pod 进入 CrashLoopBackOff 状态，然后重新启动。然后这种情况会一直循环发生。
我使用 Ubuntu 22.04 作为主服务器，并且有 2 个 Ubuntu 22.04 作为节点。
谢谢
