首先来看yaml文件默认的写法：

 name: kube-flannel
      image: quay-mirror.qiniu.com/coreos/flannel:v0.11.0-amd64
      command:
      - /opt/bin/flanneld
      args:
      - --ip-masq
      - --kube-subnet-mgr
      resources:
        requests:
          cpu: "100m"
          memory: "50Mi"

然后看一下本地镜像

[root@master opt]# docker images|grep fla
lizhenliang/flannel                                               v0.11.0-amd64       ff281650a721        11 months ag

然后可以发现，本地并没有这个镜像

quay-mirror.qiniu.com/coreos/flannel:v0.11.0-amd64

所以，有两个解决方法：

1：拉取默认配置镜像

2：修改yaml文件，使用替代镜像
