什么是Clusterpedia
Clusterpedia 这个名称借鉴自 Wikipedia，是多集群的百科全书，其核心理念是收集、检索和简单控制多集群资源。
通过聚合收集多集群资源，在兼容 Kubernetes OpenAPI 的基础上额外提供更加强大的检索功能，让用户更方便快捷地在多集群中获取想要的任何资源。

支持的功能
- 支持复杂的检索条件、过滤条件、排序、分页等等
- 支持查询资源时请求附带关系资源
- 统一主集群和多集群资源检索入口
- 兼容 kubernetes OpenAPI，可以直接使用 kubectl 进行多集群检索，而无需第三方插件或者工具
- 兼容收集不同版本的集群资源，不受主集群版本约束
- 资源收集高性能，低内存
- 根据集群当前的健康状态，自动开始/停止资源收集
- 插件化存储层，用户可以根据自己需求使用其他存储组件自定义存储层
- 高可用
基于之前velero实验拓展
# kubectl get pediacluster
NAME READY VERSION APISERVER
104-k8s True v1.26.6 https://10.1.6.104:6443
66-k8s True v1.19.0 https://10.2.6.66:16443
# ll pediacluster-66-k8s.yaml pediacluster-1016104-k8s.yaml
-rw-r--r-- 1 root root 7760 5月 21 11:37 pediacluster-1016104-k8s.yaml
-rw-r--r-- 1 root root 7686 5月 21 11:28 pediacluster-66-k8s.yaml
我们这里可以看到自己的两个k8s集群环境已经可以展示了
如下的命令，可以看到数据中的一些信息已经已经记录了两个集群的信息
