用老的生成token方式
kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"
报错
error: error executing template "{{.data.token | base64decode}}": template: output:1:16: executing "

解决方案：
用
kubectl -n kubernetes-dashboard create token admin-user

兜兜转转找了好久问题

无线通信中的高级仿真技术：云仿真技术_（11）.云仿真技术的发展趋势
2401_87715305的博客

云计算技术的发展为仿真技术提供了强大的支持，使得大规模、复杂、高精度的仿真成为可能。传统的仿真技术通常依赖于本地计算资源，这在处理大规模仿真任务时存在明显的局限性，如计算能力不足、存储资源有限、扩展性差等。而云计算通过虚拟化技术、分布式计算和弹性资源管理，能够提供几乎无限的计算和存储资源，从而大大提高了仿真任务的效率和精度。
