kubernetes1.9中部署dashboard

在1.9k8s中 dashboard可以有两种访问方式

kubeconfig（HTTPS）和token（http）

2018-03-18

一、基于token的访问
1、下载官方的dashboard
wget https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
2、编辑yaml文件
1）添加类型nodeport
spec:
type: NodePort
ports:
- port: 443
targetPort: 8443
selector:
2）修改镜像为自己可用的镜像
image: gcr.io/google_containers/kubernetes-dashboard-amd64:v1.8.3
3、创建pod
kubectl create -f kube-dashboard-admin.yaml

4、查看pod
kubectl get svc,pod --all-namespaces | grep dashboard
kube-system svc/kubernetes-dashboard NodePort 10.254.15.217 <none> 443:27446/TCP 19h
kube-system po/kubernetes-dashboard-cdc8db7d-7xnsw 1/1 Running 0 19h

5、创建RBAC
vim kube-dashboard-admin.yaml
---
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-admin
namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
name: kubernetes-dashboard-admin
labels:
k8s-app: kubernetes-dashboard
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: kubernetes-dashboard-admin
namespace: kube-system

6、修改deployment文件中的ServiceAccount名称
146 serviceAccountName: kubernetes-dashboard-admin
重启pod
kubectl apply -f kubernetes-dashboard.yaml -f kubernetes-dashboard-admin.rbac.yaml
7、查看RBAC的token登录UI界面时用
kubectl -n kube-system get secret | grep kubernetes-dashboard-admin

kubectl describe -n kube-system secret kubernetes-dashboard-admin-token-7ss4x

8、使用proxy暴露服务
kubectl proxy --address='192.168.11.70' --port=23455 --accept-hosts='^*$' &
9访问 192.168.11.70:2355/ui
访问dashboard后直接skip就可以了

二、利用token或是kubeconfig登录dashboard

首先：kubeconfig就是.kube/config文件
但是得手动的将token放到里面
1、wget下载dashboard
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/dashboard/yaml-file/admin-rbac.yaml
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/dashboard/yaml-file/kube-rbac.yaml
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/dashboard/yaml-file/kubernetes-dashboard.yaml
配置apiserver服务
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/heapster/yaml-file/kube-apiserver.service

2、修改master上的API
vim /etc/systemd/system/kube-apiserver.service

重启API
systemctl daemon-reload
systemctl restart kube-apiserver
systemctl status kube-apiserver

3、部署heapster服务
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/heapster/yaml-file/grafana.yaml
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/heapster/yaml-file/heapster-rbac.yaml
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/heapster/yaml-file/heapster.yaml
wget https://raw.githubusercontent.com/deauss2017/k8s/master/1.9/heapster/yaml-file/influxdb.yaml

按顺序创建
heapster-rbac.yaml>>>>> influxdb.yaml >>>>> heapster.yaml >>>>> grafana.yaml

注：在k8s中服务的域名是：
服务名.空间名.svc.cluster.local
例如：
monitoring-influxdb.kube-system.svc.cluster.local

# 部署dashboard 主yaml配置文件
kubectl create -f kubernetes-dashboard.yaml
kubectl create -f ui-admin-rbac.yaml
kubectl create -f ui-read-rbac.yaml
kubectl create -f admin-user-sa-rbac.yaml
3、验证
kubectl get pod -n kube-system | grep dashboard
kubectl get svc -n kube-system|grep dashboard
kubectl cluster-info|grep dashboard

4、修改apiserver配置
修改配置文件中的IP

basic-auth.csv设置dashboard密码登录
格式：密码，用户，ID号
例如：
admin123, admin, 2

重启master
5、登录
https://192.168.11.70:6443/ui
https://192.168.11.70:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/ingress?namespace=default

使用token访问
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')

将token复制到对话框中点击登录
使用kubeconfig访问
上传config配置文件到Windows上
sz /root/.kube/config
将上边的token添加到config中

注：
1、apiserver中开启了RBAC认证，所以要锁RBAC
2、kubeconfig = ./kube/conf = kubernetes.pem要在config文件的最后添加token信息才能访问
3、修改API组件的配置文件 添加密码和用登录认证，开启CA认证，关闭匿名访问
--authorization-mode=Node,RBAC \ 开启RBAC认证
--anonymous-auth=false \ 关闭匿名访问
--basic-auth-file=/etc/kubernetes/ssl/basic-auth.csv \ 添加密码和用登录认证（密码，用户名，ID号）
4、访问方式一共有三种：
1）通过kubectl proxy访问
kubectl proxy --address='192.168.11.70' --port=23455 --accept-hosts='^*$' &
访问 192.168.11.70:2355/ui

2)通过API访问（密码+用户名+token(kubeconfig)）
https://192.168.11.70:6443/ui
https://192.168.11.70:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login
