kubeedge: can't deploy nginx-deployment sample succeed

What happened: When I finished setup KubeEdge, then I test the sample nginx-deployment using kubectl apply -f $GOPATH/src/github.com/kubeedge/kubeedge/build/deployment.yaml, the status is Pending (I wait for 8 min, it’s still pending), then I delete it, the status is Terminating(I wait for a long time but it is still Terminating). See below for more.

What you expected to happen: nginx-deployment is running well.

How to reproduce it (as minimally and precisely as possible): follow the doc.

Anything else we need to know?:

Environment:

• KubeEdge version(e.g. cloudcore/edgecore --version):

./cloudcore --version
KubeEdge v1.2.1-dirty

CloudSide Environment:

• Hardware configuration (e.g. lscpu): Intel(R) Core(TM) i3-4150 CPU @ 3.50GHz
• OS (e.g. cat /etc/os-release): Ubuntu 16.04 LTS x86_64
• Kernel (e.g. uname -a): ubuntu 4.4.0-174
• Go version (e.g. go version): go1.12.14 linux/amd64
• Others:

EdgeSide Environment: the same as CloudSide

1. checking the system after setup KubeEdge, the node status is:

# kubectl get node
NAME         STATUS   ROLES    AGE   VERSION
edge-node    Ready    edge     31m   v1.17.1-kubeedge-v1.2.0
edge-node2   Ready    edge     30m   v1.17.1-kubeedge-v1.2.0
ubuntu       Ready    master   68m   v1.17.4

the node is ready, and the crds is as follows:

# kubectl get crds
NAME                                           CREATED AT

1. deploy nginx:

kubectl apply -f $GOPATH/src/github.com/kubeedge/kubeedge/build/deployment.yaml

but it is pending.

1. after some time, it still pending:

# kubectl get pod
NAME                                           READY   STATUS        RESTARTS   AGE
nginx-deployment-77698bff7d-jdm8k              0/1     Pending       0          12m

1. check the information:

# kubectl describe pod nginx-deployment-77698bff7d-jdm8k

  Normal  Scheduled  13m   default-scheduler  Successfully assigned default/nginx-deployment-77698bff7d-jdm8k to edge-node2

The only I know from the information is the deployment is assigned to the node, nothing else.

1. try to get the log but refused:

# kubectl logs nginx-deployment-77698bff7d-jdm8k
Error from server: Get https://192.168.0.153:10250/containerLogs/default/nginx-deployment-77698bff7d-jdm8k/nginx: dial tcp 192.168.0.153:10250: connect: connection refused

1. finaly I delete it.

# kubectl delete -f $GOPATH/src/github.com/kubeedge/kubeedge/build/deployment.yaml
deployment.apps "nginx-deployment" deleted

it is terminating:

# kubectl get pod
NAME                                           READY   STATUS        RESTARTS   AGE
