Kubernetes Dashboard的安裝與配置

一背景

經過kubeadm快速完成了kubernetes的安裝，便可迅速地體驗到kubernetes的強大功能。美中不足的是，只能經過命令來查看或操做，沒有一個直觀且簡潔的Web UI來感覺一下這種成功的喜悅。此外，國內的網絡環境，也在某種程度上增長了一些門檻。面對如此種種，依然有辦法體驗kunernetes dashboard。git

二操做步驟

由於不清楚Pod會被調度到哪個Node上，因此在每個節點上執行如下腳本：github

#!/bin/bash
docker pull registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0
# docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-amd64:v1.10.0
docker tag registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0 k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.0
docker image rm registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0

在Master節點上執行：docker

[root@k8s-m ~]# curl -O kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.0/src/deploy/recommended/kubernetes-dashboard.yaml
[root@k8s-m ~]# kubectl apply -f kubernetes-dashboard.yaml

查看pod是否建立成功:api

[root@k8s-m ~]#  kubectl get pods --namespace=kube-system
NAME                                    READY   STATUS    RESTARTS   AGE
coredns-576cbf47c7-xg4xm                1/1     Running   1          72m
coredns-576cbf47c7-xq9mc                1/1     Running   1          80m

kube-apiserver-k8s-m                    1/1     Running   2          79m
kube-controller-manager-k8s-m           1/1     Running   21         80m

kube-flannel-ds-amd64-nddqf             1/1     Running   2          72m

kube-proxy-lp2v2                        1/1     Running   2          72m
kube-scheduler-k8s-m                    1/1     Running   19         80m
kubernetes-dashboard-77fd78f978-ngkvb   1/1     Running   1          25m

修改service配置，找到type，將ClusterIP改爲NodePort：瀏覽器

[root@k8s-m ~]# kubectl edit service  kubernetes-dashboard --namespace=kube-system

查看暴露端口:bash

[root@k8s-m ~]#  kubectl get service --namespace=kube-system
NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.96.0.10       <none>        53/UDP,53/TCP   87m
kubernetes-dashboard   NodePort    10.101.204.129   <none>        443:31269/TCP   32m

建立kubernetes-dashboard用戶:網絡

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: admin
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: ServiceAccount
  name: admin
  namespace: kube-system
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin
  namespace: kube-system
  labels:
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile

建立用戶:app

[root@k8s-m ~]#  kubectl create -f admin-token.yaml

獲取登陸token:curl

[root@k8s-m ~]# kubectl get secret -n kube-system |grep admin|awk '{print $1}'
admin-token-6tkxm

[root@k8s-m ~]# kubectl describe secret admin-token-6tkxm -n kube-system|grep '^token'|awk '{print $2}'
