這篇文章主要介紹了k8s dashboard安裝過程記錄,本案例k8s版本為v1.22.17,所以安裝v2.7.0版本的dashboard,需要的朋友可以參考下

1、下載dashboard的yaml文件

curl -O https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

2、修改recommended.yaml文件

修改定義的Service，將type由ClusterIP修改為NodePort，以便我們直接通過地址+端口進行訪問，并配置訪問端口。添加的內(nèi)如為：

type: NodePortnodePort: 31111

如下圖：

3、kubectl create 生成pod

執(zhí)行

kubectl create -f recommended.yaml

查看 pod

kubectl  get pods --all-namespaces

4、訪問https://192.168.0.107:31111

5、生成token

1）創(chuàng)建dashboard-adminuser.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard

2）執(zhí)行 kubectl apply -f dashboard-adminuser.yaml

kubectl apply -f dashboard-adminuser.yaml

3）創(chuàng)建admin-user-role-binding.yaml

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: admin-user
    namespace: kubernetes-dashboard

4）執(zhí)行kubectl create -f admin-user-role-binding.yaml

5）生成token

kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"

root@k8s-master:/usr/java/k8s-dashboard# kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"
