zhu733756 另一个细节，我安装完成kubeedge后，添加边缘节点时没有问题，在边缘端部署pod时，报了个错误：
cloudcore报错如下
upstream.go:728] apiserver get service account token failed: err serviceaccounts "default" is forbidden: User "system:serviceaccount:kubeedge:cloudcore" cannot create resource "serviceaccounts/token" in API group "" in the namespace "demo-project"
edge端日志报错如下
record.go:24] Warning FailedMount MountVolume.SetUp failed for volume "kube-api-access-9wsv8" : get service account token from metaManager failed, err: timed out waiting for the condition
我的解决办法是给cloudcore增加了serviceaccounts/token的create权限，后续可以部署，但是日志和exec不能访问，不知道和这个有没有关系
