我有以下mysql.yaml文件：

apiVersion: v1beta3
kind: Pod
Metadata:
  name: MysqL
  labels:
    name: MysqL
spec:
  containers:
    - resources:
        limits :
          cpu: 1
      image: MysqL
      name: MysqL
      env:
        - name: MysqL_ROOT_PASSWORD
          # change this
          value: yourpassword
      ports:
        - containerPort: 3306
          name: MysqL

运行kubectl create -f MysqL.yaml会给出错误：

Error from server: error when creating "MysqL.yaml": Pod "Unknown" is forbidden: no API token found for service account default/default,retry after the token is automatically created and added to the service account

我有一个主机和一个节点,都是centos 7.1.
