部署dashboard

一、部署kubernates

使用kubephere安装的kubernates系统，安装完成的截图

创建集群

./kk create cluster -f config-sample.yaml

删除集群

./kk delete cluster -f config-sample.yaml

docker镜像打包或者解压

docker save zhxl1989/ingress-nginx-controller:v1.2.1 | gzip > ingress-nginx-controller.tar.gzgunzip -c ingress-nginx-controller.tar.gz | docker load

安装dashboard，参考文档

dashboard/installation.md at master · kubernetes/dashboard (github.com)

第一步、创建本地证书存储目录

mkdir -p /root/certs

第二步、创建dashboard的名称空间

kubectl create namespace kubernetes-dashboard

第三步、创建证书

 kubectl create secret generic kubernetes-dashboard-certs --from-file=/certs -n kubernetes-dashboard kubectl get secret -n kubernetes-dashboard kubectl describe secret kubernetes-dashboard-certs -n kubernetes-dashboard

生成证书 kubectl get secret -A

自签名证书
如果您想自己生成证书，则需要像OpenSSL这样的库来帮助您做到这一点。生成私钥和证书签名请求
创建 SSL 证书需要私钥和证书签名请求。这些可以通过几个简单的命令生成。当 openssl req 命令要求输入“质询密码”时，只需按回车键，将密码留空即可。证书颁发机构使用此密码在证书所有者想要吊销其证书时对其进行身份验证。由于这是自签名证书，因此无法通过 CRL（证书吊销列表）将其吊销。openssl genrsa -des3 -passout pass:over4chars -out dashboard.pass.key 2048
...
openssl rsa -passin pass:over4chars -in dashboard.pass.key -out dashboard.key
# Writing RSA key
rm dashboard.pass.key
openssl req -new -key dashboard.key -out dashboard.csr
...
Country Name (2 letter code) [AU]: US
...
A challenge password []:
...
生成 SSL 证书
自签名 SSL 证书是从私钥和文件生成的。dashboard.keydashboard.csropenssl x509 -req -sha256 -days 365 -in dashboard.csr -signkey dashboard.key -out dashboard.crt
该文件是适合与仪表板一起使用的证书以及私钥。dashboard.crtdashboard.key

网络的原因，部分镜像需要从aliyun拉取，再本地进行tag改名

查看官网文档，kubernates与Dashboard对应的版本。

docker pull registry.aliyuncs.com/google_containers/dashboard:v2.5.1
docker tag registry.aliyuncs.com/google_containers/dashboard:v2.5.1 kubernetesui/dashboard:v2.5.1
docker pull registry.aliyuncs.com/google_containers/metrics-scraper:v1.0.7
docker tag registry.aliyuncs.com/google_containers/metrics-scraper:v1.0.8 kubernetesui/metrics-scraper:v1.0.7

第四步、kubectl create --edit -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

镜像拉取方式改为：imagePullPolicy: IfNotPresent 及证书路径，secrets的配置

改成dashboard.yaml

第五步、运行修改后的dashboard配置文件

kubectl apply -f dashboard.yaml

第六步、查看所有运行的pod

kubectl get pods -A查看启动详情kubectl describe pod kubernetes-dashboard -n kubernetes-dashboard

第七步、创建create-admin.yaml 并 kubectl apply -f create-admin.yaml。

apiVersion: v1
kind: ServiceAccount
metadata:name: adminnamespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:name: adminnamespace: kubernetes-dashboard
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:
- kind: ServiceAccountname: adminnamespace: kubernetes-dashboard

第八步、查看登录的Token，Ingress访问时候使用

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin | awk '{print $1}')

第九步、kubectl apply -f nginx-ingress-controller.yaml

可参考

Kubernetes部署kubernates Nginx Ingress Controller_青春不流名的博客-CSDN博客

Kubernetes：在没有主机且没有代理的情况下通过Ingress路由Kubernetes仪表板 - 编程之家 (jb51.cc)

第十步、配置访问Ingress，kubectl apply -f k8s-dashboard-ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:annotations:nginx.ingress.kubernetes.io/rewrite-target: /nginx.ingress.kubernetes.io/add-base-url: "true"nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"nginx.ingress.kubernetes.io/secure-backends: "true"nginx.ingress.kubernetes.io/force-ssl-redirect: "true"ingress.kubernetes.io/configuration-snippet: |rewrite ^(/dashboard)$ $1/ permanent;name: nginx-ingressnamespace: kubernetes-dashboard

查看Ingress信息

kubectl describe ingress/nginx-ingress -n kubernetes-dashboard
