在host cluster上装kubeedge的cloudcore，然后 用real node all的模式启动一个vcluster，然后往host上添加边缘节点，看看vcluster里面能不能看到添加的边缘节点，能看到的话，能不能往边缘节点上调度一个niginx

下载vcluster

curl -L -o vcluster "https://github.com/loft-sh/vcluster/releases/latest/download/vcluster-linux-amd64" && sudo install -c -m 0755 vcluster /usr/local/bin

看一下vcluster有哪些

root@kubeedge:~# vcluster list

 NAME          NAMESPACE              STATUS    CONNECTED   CREATED                         AGE
 my-vcluster   vcluster-my-vcluster   Running               2022-10-18 15:35:21 +0800 CST   48h42m3s

删除原来的vcluster

vcluster disconnect

vcluster delete my-vcluster

新建value.yaml

sync:
  nodes:
    enabled: true
    syncAllNodes: true
  persistentvolumes:
    enabled: true
  # If you want to create custom storage classes
  # inside the vcluster.
  storageclasses:
    enabled: true

创建vcluster集群

vcluster create my-vcluster --kubernetes-version v1.21 --distro k8s  -f values.yaml

在vcluster集群中：

root@vrcluster:~# kubectl get pods -A
NAMESPACE     NAME                       READY   STATUS    RESTARTS   AGE
kube-system   coredns-749456dcbf-vfz9s   1/1     Running   0          8m41s

在这里部署sc，这里需要name和外部sc一致。其实vcluster中sc本质上还是使用外部的sc，所以其他配置选项都可以随便填，我这里导出的是host集群的sc。主要是为了ks-installer中检测sc是否存在，防止安装失败

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    cas.openebs.io/config: |
      - name: StorageType
        value: "hostpath"
      - name: BasePath
        value: "/var/openebs/local/"
    openebs.io/cas-type: local
    storageclass.beta.kubernetes.io/is-default-class: "true"
    storageclass.kubernetes.io/is-default-class: "true"
    storageclass.kubesphere.io/supported-access-modes: '["ReadWriteOnce"]'
  creationTimestamp: "2022-10-24T07:09:18Z"
  name: local
  resourceVersion: "433221"
  uid: 595cda9a-f85d-4dfc-a83c-fcb9e63a6a02
provisioner: openebs.io/local
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

部署ks

kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/kubesphere-installer.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/cluster-configuration.yaml

kubectl edit cc -n kubesphere-system

把这个端口改一下，因为是nodeport，要不然sync会显示端口被占用。

common:
    core:
      console:
        enableMultiLogin: true
        port: 30885
        type: NodePort

这是可以通过ip:30885访问vcluster的集群了。

部署边缘节点，进入vcluster集群,可以看到node节点（注意vrcluster是host集群的，边缘是1.21）

NAME            STATUS   ROLES                         AGE    VERSION
edgenode-z1h8   Ready    agent,edge                    114s   v1.21.4-kubeedge-v1.9.2
vrcluster       Ready    control-plane,master,worker   70m    v1.22.10

部署一个nginx

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
  - name: nginx
    image: nginx
  nodeName: edgenode-z1h8

root@vrcluster:~# kubectl get pods
NAME    READY   STATUS    RESTARTS   AGE
nginx   1/1     Running   0          119m

在vcluster集群中，查看pod，并没有该边缘节点pod

root@vrcluster:~# kubectl get pods -A
NAMESPACE                      NAME                                               READY   STATUS    RESTARTS   AGE

总结：在host cluster上装kubeedge的cloudcore，然后 用real node all的模式启动一个vcluster，然后往host上添加边缘节点，vcluster里面可以看到添加的边缘节点，但不能查看到边缘节点的pod
