kubernetes1.9部署dashboard1.8.3

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

---------------------------------

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             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 | grepkubernetes-dashboard-admin

kubectl describe -nkube-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

参考文档：

https://github.com/gjmzj/kubeasz/blob/master/docs/guide/dashboard-1.8.2.md

https://jimmysong.io/posts/kubernetes-dashboard-upgrade/

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/Examples/master/dashboard/http/admin-role.yaml

wget   https://raw.githubusercontent.com/deauss2017/Examples/blob/master/dashboard/http/kubernetes-dashboard-admin.rbac.yaml

wget   https://raw.githubusercontent.com/deauss2017/Examples/master/dashboard/http/kubernetes-dashboard-http.yaml

2、修改master上的API

vim /etc/systemd/system/kube-apiserver.service

重启API

systemctldaemon-reload

systemctl restartkube-apiserver

systemctl statuskube-apiserver

3、部署heapster服务

wget   https://raw.githubusercontent.com/deauss2017/Examples/master/dashboard/https/grafana.yaml

wget   https://raw.githubusercontent.com/deauss2017/Examples/blob/master/dashboard/https/heapster-rbac.yaml

wget   https://raw.githubusercontent.com/deauss2017/Examples/blob/master/dashboard/https/heapster.yaml

wgeth   ttps://raw.githubusercontent.com/deauss2017/Examples/blob/master/dashboard/https/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

 kubectlcreate -fadmin-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

[if !vml]

[endif]

使用token访问

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

[if !vml]

[endif]

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

[if !vml]

[endif]

[if !vml]

[endif]

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
