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 ~]# ./kk create cluster --with-kubernetes v1.22.12 3. 部署Kubernetes Dashboard
javascript
[root@flexusx-3e9a ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
[root@flexusx-3e9a ~]# grep image recommended.yaml

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

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）：
javascript
[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
javascript
[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
javascript
[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

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。
