超时：请求未在允许的时间内完成

Question

使用kubernetes的Initializers启用LXCFS时遇到了一些问题。

ENV：内核3.10，centos7.5，k8s1.11.3

在使用守护程序部署lxcfs-initializer之后，当我在yaml中添加注释："initializer.kubernetes.io/lxcfs": "true"时，容器运行成功。

但是，如果没有此注释，当我尝试创建部署时，会出现以下错误：

[root@master1 ~]# kubectl apply -f test.yaml 
service/nginx-service created
Error from server (Timeout): error when creating "test.yaml": Timeout: request did not complete within allowed duration

这是我的test.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx 
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx 
        image: nginx:1.14 
        imagePullPolicy: Always 
        ports: 
        - name: service-port
          containerPort: 80 
        resources: 
          requests: 
            memory: "250Mi"
            cpu: "0.5"
          limits: 
            memory: "500Mi"
            cpu: "1"
        volumeMounts:
            - name: timezone
              mountPath: /etc/localtime
      restartPolicy: Always 
      volumes:
        - name: timezone
          hostPath:
            path: /usr/share/zoneinfo/Asia/Shanghai

此外，lxcfs-initializer正在运行，

[root@master1 ~]# kubectl get pods
NAME                                 READY     STATUS    RESTARTS   AGE
