1. 基础部署环境说明

   Kubernetes作为当今最流行的容器编排平台，随着云计算、微服务架构和DevOps文化的普及，Kubernetes在自动化部署、扩展和管理容器化应用程序方面扮演着越来越重要的角色。未来Kubernetes将继续优化其稳定性、安全性和易用性，以满足企业级应用的需求。同时随着边缘计算、AI和大数据等技术的融合，Kubernetes有望成为支撑下一代分布式应用的基础设施，推动整个IT行业的创新与发展。
   本次选择使用华为Flexus云服务器X实例部署Kubernetes图形化管理平台，因为最近华为云828 B2B企业节正在举办，选择Flexus X云主机实例，享受定制化性能优化、99.99%的高可用性保障，以及全面的技术支持，让您的业务飞速发展，云端无忧！

 

2. 部署Kubernetes环境

   因为本次主要是在Flexus云服务器X实例中部署Kubernetes图形化管理平台，所以Kubernetes环境的部署不是本篇的重点内容，但是Kubernetes图形化管理平台又依赖Kubernetes环境，所以本次使用kk工具进行Kubernetes环境的部署。当然如果自己有Kubernetes环境，也可以跳过本章节，直接进行下面的部署过程。

[root@flexusx-3e9a ~]# export KKZONE=cn
[root@flexusx-3e9a ~]# curl -sfL https://get-kk.kubesphere.io | VERSION=v2.3.0 sh -

[root@flexusx-3e9a ~]# tar xvf kubekey-v2.3.0-linux-amd64.tar.gz
[root@flexusx-3e9a ~]# ./kk version --show-supported-k8s
v1.19.0
v1.19.8
v1.19.9
v1.20.4
v1.20.6
v1.20.10
v1.21.0
v1.21.1
……

[root@flexusx-3e9a ~]# ./kk create cluster --with-kubernetes v1.22.12 

3. 部署Kubernetes Dashboard

   部署和访问Kubernetes Dashboard官方手册

[root@flexusx-3e9a ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

[root@flexusx-3e9a ~]# grep image recommended.yaml
          image: registry.cn-hangzhou.aliyuncs.com/cloud_wzy/dashboard:v2.7.0
          imagePullPolicy: IfNotPresent
          image: registry.cn-hangzhou.aliyuncs.com/cloud_wzy/metrics-scraper:v1.0.8

[root@flexusx-3e9a ~]# kubectl apply -f recommended.yaml

[root@flexusx-3e9a ~]# kubectl get ns
NAME                   STATUS   AGE
kubernetes-dashboard   Active   21s

[root@flexusx-3e9a ~]# kubectl get pods -n kubernetes-dashboard
NAME                                        READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-66fbb549b-g9n2j   1/1     Running   0          47s
kubernetes-dashboard-67c5c7dc6b-fqpnv       1/1     Running   0          47s

[root@flexusx-3e9a ~]# kubectl get svc -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
dashboard-metrics-scraper   ClusterIP   10.102.209.140   <none>        8000/TCP   2m12s
kubernetes-dashboard        ClusterIP   10.101.169.76    <none>        443/TCP    2m12s


[root@flexusx-3e9a ~]# kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
......
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: NodePort


[root@flexusx-3e9a ~]# kubectl get svc -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.102.209.140   <none>        8000/TCP        8m49s
kubernetes-dashboard        NodePort    10.101.169.76    <none>        443:30156/TCP   8m49s

4. 创建登录账号token

   创建SA（此SA账号用于和集群内的程序交互使用，可以参考我的其他博客了解SA账号作用）：

[root@flexusx-3e9a ~]# kubectl create sa dashboardsa -n kube-system
[root@flexusx-3e9a ~]# kubectl get sa -n kube-system | grep dashboardsa
dashboardsa                          0         57s

[root@flexusx-3e9a ~]# kubectl create clusterrolebinding rolebind-dashboard --clusterrole admin --serviceaccount kube-system:dashboardsa -n kube-system

   因为从kubernetes 1.24版本开始，创建SA不再自动生成secrets，所以接下来需要手动创建一个secrets
   手动创建secrets：官方参考手册

[root@flexusx-3e9a ~]# vim dashboardsa-secret.yaml
[root@flexusx-3e9a ~]# cat dashboardsa-secret.yaml
apiVersion: v1
kind: Secret
metadata:
  name: secret-sa-sample
  annotations:
    kubernetes.io/service-account.name: "dashboardsa"
type: kubernetes.io/service-account-token

[root@flexusx-3e9a ~]# kubectl apply -f dashboardsa-secret.yaml -n kube-system
[root@flexusx-3e9a ~]# kubectl get secrets -n kube-system
NAME               TYPE                                  DATA   AGE
secret-sa-sample   kubernetes.io/service-account-token   3      12s

[root@flexusx-3e9a ~]# kubens kube-system
[root@flexusx-3e9a ~]# kubectl describe secrets secret-sa-sample
Name:         secret-sa-sample
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboardsa
              kubernetes.io/service-account.uid: 90bc6cea-5b6e-4a14-b271-3e3f26cb87a4

Type:  kubernetes.io/service-account-token

5. 访问Kubernetes Dashboard

  也可以选择使用Kubeconfig方式登录，将kubernetes集群中/etc/kubernetes/admin.conf文件下载到本地，然后再上传到此处即可。
