## multi-cluster-k8s-manager-demo
## k8s多集群后端接口展示demo
### 项目思路：
对多个集群采用informer的方式管理k8s资源，server中使用key为集群名的方式区分不同集群。
### 启动步骤：
1. 目录下创建一个resources文件，把集群的.kube/config文件复制一份放入(记得cluster server需要改成"公网ip")。
2. 本项目使用insecurity模式，所以config文件需要把certificate-authority-data字段删除，否则连接会报错。
3. 可以放置多个.kube/config配置文件，支持多集群list查询。
4. go run main.go启动服务
```
➜ mutli-cluster-k8s-manager git:(main) ✗ go run main.go
cluster https://xxxxxx:6443 start informer!!
cluster https://xxxxxx:6443 start informer!!
cluster https://xxxxxx start informer!!

5. 接口调用测试：
注意：调用接口时，如果不写query，cluster默认取第一个集群的结果，namespace默认取default
```
http://localhost:8080/pods
http://localhost:8080/deployments
http://localhost:8080/clusters
http://localhost:8080/nodes?cluster=cluster1
http://localhost:8080/pods?cluster=cluster0
http://localhost:8080/pods?cluster=cluster0&namespace=default
http://localhost:8080/deployments?cluster=cluster1&namespace=default
```
### RoadMap
1. 本项目基于多集群实现，目前预计支持多个资源的展示与查询。
2. 未来会加入前端，方便可视化。
