# k8s-client-go-practice-deployment
### 项目思路逻辑
结合**golang**+**k8s**+**client-go**实现restful-http-api 简易管理系统

### 项目依赖
```bigquery
目前暂无，预计提供mysql建立表存储。
```
### 项目启动
1. 启动
```bigquery
cd 进入项目根目录
[root@vm-0-12-centos k8s-api-practice]# go build
[root@vm-0-12-centos k8s-api-practice]# ./k8s-client-go-api-practice

```
2. 浏览器+使用postman调用
### 预计提供方法
```bigquery
1. list deployment:获取deployment列表 (完成)
2. get deployment:获取特定deployment (完成)
3. delete deployment:删除特定deployment
4. 增减deployment副本 (完成)
5. update deployment:自定义更新deployment
6. create deployment:创建deployment
```
### list-watch
```
list:http短链接调用资源的Api，获取列表 => 或有大量请求的缺点
watch:http长连接持续监听资源，有变化则返回一个watchEvent
使用client-go中的informer可以对list-watch机制进行封装。
解释：
1.刚开始初始化，调用list api获取全量list，并缓存起来。
2.调用watch api去watch资源，发生变更后会通过机制维护缓存(不需要每次都请求api server)
```
