kind搭建k8s单节点集群

1【kind 安装】

kind create clouster

　　查看节点信息

lory@lory-PC:~$ kubectl cluster-info
Kubernetes master is running at https://127.0.0.1:39377
KubeDNS is running at https://127.0.0.1:39377/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'

 

解决bug:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "forbidden: User \"system:anonymous\" cannot get path \"/metrics\"",
  "reason": "Forbidden",
  "details": {

  },
  "code": 403
}

 

请执行:

kubectl create clusterrolebinding prometheus-admin --clusterrole cluster-admin --user system:anonymous

　　

查看节点:

lory@lory-PC:~$ kubectl get node
NAME                 STATUS   ROLES    AGE   VERSION
kind-control-plane   Ready    master   30h   v1.18.2

　　

 

2【创建对应服务】

安装 Kuboard

lory@lory-PC:~$ kubectl create clusterrolebinding prometheus-admin --clusterrole cluster-admin --user system:anonymous
clusterrolebinding.rbac.authorization.k8s.io/prometheus-admin created
lory@lory-PC:~$ kubectl apply -f https://kuboard.cn/install-script/kuboard.yaml

　　

lory@lory-PC:~$ kubectl apply -f https://addons.kuboard.cn/metrics-server/0.3.6/metrics-server.yaml
clusterrole.rbac.authorization.k8s.io/system:aggregated-metrics-reader created
clusterrolebinding.rbac.authorization.k8s.io/metrics-server:system:auth-delegator created
rolebinding.rbac.authorization.k8s.io/metrics-server-auth-reader created
clusterrole.rbac.authorization.k8s.io/system:metrics-server created
clusterrolebinding.rbac.authorization.k8s.io/system:metrics-server created
apiservice.apiregistration.k8s.io/v1beta1.metrics.k8s.io created
serviceaccount/metrics-server created
deployment.apps/metrics-server created
service/metrics-server created

 

查看 Kuboard 运行状态：

输出结果如下所示：

lory@lory-PC:~$ kubectl get pods -l k8s.kuboard.cn/name=kuboard -n kube-system
NAME                       READY   STATUS    RESTARTS   AGE
kuboard-7bb89b4cc4-g268r   1/1     Running   0          49s

　　

获取Token

此Token拥有 ClusterAdmin 的权限，可以执行所有操作

执行命令

lory@lory-PC:~$ echo $(kubectl -n kube-system get secret $(kubectl -n kube-system get secret | grep kuboard-user | awk '{print $1}') -o go-template='{{.data.token}}' | base64 -d)
