今天我们一起来安装一下Clusterpedia，看看Clusterpedia的功能。
安装
Clusterpedia代码目录deploy下提供了kubectl安装Clusterpedia的YAML文件。部署数据库，安装CRD自定义资源，安装apiserver和clustersynchro，注册apiservice。
cd ./deploy/internalstorage/postgres
export STORAGE_NODE_NAME=sukai
sed "s|__NODE_NAME__|$STORAGE_NODE_NAME|g" `grep __NODE_NAME__ -rl ./templates` > clusterpedia_internalstorage_pv.yaml
kubectl create -f .
cd ../../..
kubectl apply -f ./deploy/crds
kubectl apply -f ./deploy
两个组件的deployment里可以修改镜像地址为：
m.daocloud.io/ghcr.io/clusterpedia-io/clusterpedia/clustersynchro-manager:v0.1.0
m.daocloud.io/ghcr.io/clusterpedia-io/clusterpedia/apiserver:v0.1.0
导入集群
创建Clusterpedia的CRD PediaCluster资源实例，syncResources指定Clusterpedia需要同步的资源。

总结
Clusterpedia提供的用户请求API为/apis/clusterpedia.io/v1beta1/resources/clusters/{cluster-sukai}或/apis/clusterpedia.io/v1beta1/resources两种，指定集群和所有集群。资源请求处理后，将cluster信息保存到context中，API为/apis/clusterpedia.io/v1beta1/resources/api和/apis/clusterpedia.io/v1beta1/resources/apis。通过Aggregator方式由genericServer注册API资源，Group/Version为clusterpedia.io/v1beta1，Resource为collectionresources，resources。genericServer将资源resources的路径/api和/apis委托给kubeResourceAPIServer提供服务。
