一、下载官方的YAML 文件

五个文件各自的作用

• dashboard-configmap.yaml ## 配置文件

• dashboard-deployment.yaml ## 部署

• dashboard-rbac.yaml 授权管理 一般来说要绑定角色

• dashboard-secrect.yaml 安全，证书验证

• dashboard-service.yaml 核心功能 提供web的

• dashboard-controller.yaml ## 控制

• 官方文件下载位置：https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/dashboard/dashboard.yaml

• 现在官方已经将5个文件合为一个文件
  

二、利用YAML文件进行服务配置

• 在master01上操作

[root@master01 k8s]# mkdir dashboard
//拷贝官方的文件
[root@master01 dashboard]# ls
dashboard-configmap.yaml   dashboard-rbmasac.yaml    dashboard-service.yaml
dashboard-controller.yaml  dashboard-secret.yaml  k8s-admin.yaml
## 要注意顺序
[root@master01 dashboard]# kubectl create -f dashboard-rbac.yaml 
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
[root@master01 dashboard]# kubectl create -f dashboard-secret.yaml 
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-key-holder created
[root@master01 dashboard]# kubectl create -f dashboard-configmap.yaml 
configmap/kubernetes-dashboard-settings created
[root@master01 dashboard]# kubectl create -f dashboard-controller.yaml 
serviceaccount/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
[root@master01 dashboard]# kubectl create -f dashboard-service.yaml 
service/kubernetes-dashboard created

2.1 完成后查看创建在指定的kube-system命名空间下

[root@localhost ~]#  kubectl get pods -n kube-system -o wide
kubernetes-dashboard-7dffbccd68-zqfwq   1/1     Running   0          3h10m   172.17.48.3   192.168.233.200   <none>
[root@localhost ~]# kubectl get pods,svc -n kube-system
NAME                                        READY   STATUS    RESTARTS   AGE
pod/kubernetes-dashboard-7dffbccd68-zqfwq   1/1     Running   0          3h7m

NAME                           TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
service/kubernetes-dashboard   NodePort   10.0.0.246   <none>        443:30001/TCP   3h9m

2.2 访问https://192.168.233.200:30001

三、证书的制作

[root@master01 dashboard]# vim dashboard-cert.sh
cat > dashboard-csr.json <<EOF
{
   "CN": "Dashboard",
   "hosts": [],
   "key": {
       "algo": "rsa",
       "size": 2048
   },
   "names": [
       {
           "C": "CN",
           "L": "BeiJing",
           "ST": "BeiJing"
       }
   ]
}
EOF

K8S_CA=$1
cfssl gencert -ca=$K8S_CA/ca.pem -ca-key=$K8S_CA/ca-key.pem -config=$K8S_CA/ca-config.json -profile=kubernetes dashboard-csr.json | cfssljson -bare dashboard
kubectl delete secret kubernetes-dashboard-certs -n kube-system
kubectl create secret generic kubernetes-dashboard-certs --from-file=./ -n kube-system

3.1 修改dashboard-controller.yaml

[root@master01 dashboard]# vim dashboard-controller.yaml
args:
          # PLATFORM-SPECIFIC ARGS HERE
          - --auto-generate-certificates
          - --tls-key-file=dashboard-key.pem       # 指定证书密钥
          - --tls-cert-file=dashboard.pem            ## 指定证书

3.2 生成证书

[root@master01 dashboard]# bash dashboard-cert.sh /root/k8s/k8s-cert/ ##生成 dashboard证书时需要ca等证书， 指定证书位置
2020/10/09 09:55:52 [INFO] generate received request
2020/10/09 09:55:52 [INFO] received CSR
2020/10/09 09:55:52 [INFO] generating key: rsa-2048
2020/10/09 09:55:52 [INFO] encoded CSR
2020/10/09 09:55:52 [INFO] signed certificate with serial number 462856100749830270426960605715828341005357971875
2020/10/09 09:55:52 [WARNING] This certificate lacks a "hosts" field. This makes it unsuitable for
websites. For more information see the Baseline Requirements for the Issuance and Management
of Publicly-Trusted Certificates, v.1.1.6, from the CA/Browser Forum (https://cabforum.org);
specifically, section 10.2.3 ("Information Requirements").
secret "kubernetes-dashboard-certs" deleted
secret/kubernetes-dashboard-certs created

3.3 更新 dashboard-controller.yaml 配置

[root@master01 dashboard] kubectl apply -f dashboard-controller.yaml 
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
serviceaccount/kubernetes-dashboard configured
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
deployment.apps/kubernetes-dashboard configured
## 如果更新失败，无法检测到配置文件的变动
[root@localhost dashboard]# kubectl delete -f dashboard-controller.yaml  ## 先删除
serviceaccount "kubernetes-dashboard" deleted
deployment.apps "kubernetes-dashboard" deleted
[root@localhost dashboard]# kubectl create  -f dashboard-controller.yaml  ## 再重新创建
serviceaccount/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created   ## 操作完成后需要检查pod分配的节点是否发生变化

3.4 再次访问https://192.168.233.200:30001

四、生成登录令牌

[root@master01 dashboard]#  kubectl create -f k8s-admin.yaml 
serviceaccount/dashboard-admin created
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created
[root@master01 dashboard]# kubectl get secret -n kube-system
NAME                               TYPE                                  DATA   AGE

default-token-2w7ds                kubernetes.io/service-account-token   3      9d
kubernetes-dashboard-certs         Opaque                                11     2m27s

kubernetes-dashboard-token-7hzbj   kubernetes.io/service-account-token   3      4m15s
[root@master01 dashboard]# kubectl describe secret dashboard-admin-token-6qpjc -n kube-system  ## 查看令牌
