delete webshow pod and recreate new one would not expose service in Kind cluster

[Colstuwjx]

I've been setup a k8s cluster using kind, and create webshow deployment via:

curl -sSL https://mirrors.chaos-mesh.org/v0.9.1/web-show/deploy.sh | sh

Things works well at the first time:

$  curl -sSL https://mirrors.chaos-mesh.org/v0.9.1/web-show/deploy.sh | sh

service/web-show unchanged
deployment.apps/web-show created
Waiting for pod running

$ curl -I http://localhost:8081

$ kubectl get pods
NAME                       READY   STATUS    RESTARTS   AGE
web-show-7b477b5c6-47wg7   1/1     Running   0          117s

After delete the pod by manually, it is broken:

$ kubectl delete pod web-show-7b477b5c6-47wg7
pod "web-show-7b477b5c6-47wg7" deleted

$ kubectl get pods
NAME                       READY   STATUS              RESTARTS   AGE

$ kubectl get pods

After dive into the deploy.sh, I found it should be port-forward issue, I've been typed the forward cmd by manually and do delete pod after one minute, and I got the following error:

kubectl port-forward --address 0.0.0.0 svc/web-show 8081:8081

Forwarding from 0.0.0.0:8081 -> 8081

It seems not a big issue though...

I encountered the same issue when I tried to do a PodKill with the ChoasMesh dashboard.
You need, at first, manually execute this line:
https://github.com/chaos-mesh/chaos-mesh/blob/master/examples/web-show/deploy.sh#L120 ,
and, then, you can execute the port-forward command as here
https://github.com/chaos-mesh/chaos-mesh/blob/master/examples/web-show/deploy.sh#L122
