kubernetes原生的dashboard 提供了非常好的可視化界面，對(duì)理解整個(gè)k8s運(yùn)行的狀態(tài)可以說(shuō)是一目了然著恩，在生產(chǎn)環(huán)境建議安裝煌贴。
- 安裝過(guò)程
1、準(zhǔn)備好kubernetes-dashboard.yaml 配置文件说榆，下載路徑kubernetes-dashboard.yaml ,因?yàn)閲?guó)內(nèi)網(wǎng)絡(luò)限時(shí)虚吟，無(wú)法訪問(wèn)鏡像倉(cāng)庫(kù)
image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
可以修改成阿里云的倉(cāng)庫(kù)地址：
image: registry.cn-hangzhou.aliyuncs.com/k8sth/kubernetes-dashboard-amd64:v1.10.0
需要增加的內(nèi)容
對(duì)外暴露30000 端口，供外部訪問(wèn)签财。

修改好上述配置文件后串慰，執(zhí)行
kubectl create -f kubernetes-dashboard.yaml
- 在Dashboard部署完成后，
1）在瀏覽器中輸入:https://{Master IP}:30001唱蒸，此處為：[https://125.145.56.78:30000]邦鲫，即可進(jìn)入dashboard的登錄界面：

2）創(chuàng)建一個(gè)管理員用戶
配置文件admin-user.yaml如下：
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:

annotations:
rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: admin-user
namespace: kube-system
kubectl create -f admin-user.yaml //完成用戶的創(chuàng)建
3）獲取管理員用戶的token:
kubectl describe secret admin-user --namespace=kube-system
# 或者
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
在以下界面輸入得到的token:
token輸入頁(yè)
以上即完成kubernetes dashboard的部署了。
