 # k8s-scheduler
-bin packing
+
+### 设计：
+1. 利用kubernetes scheduler framework提供的插件形式，自定义kubernetes的调度器
+2. 采用bin packing装箱算法实现kubernetes的调度
+3. 首先通过扩展queueSort插件，排序目前等待调度的pods队列，优先调度cpu(核数)+Mem(KB)小的pods
+4. 然后扩展score插件，根据目前node上的pod数量评分len(pods)*10，这样优先调度pods数多的node节点
+5. 由此解决尽可能少占用node节点的装箱问题
+
+### 编译：
+
+#### binary
+```shell
+$ make local
+```
+
+#### image
+```shell
+$ make image
+```
+
+### 运行
+
+#### 部署自定义调度器
+```shell
+$ kubectl apply -f ./deploy/bin-packing-plugin.yaml
+```
+
+#### 测试
+```shell
+$ kubectl apply -f ./deploy/test.yaml
+```
