前只修改

准备环境到GitHub直接下载压缩包然后解压解压要在Linux系统下完成

编写调度器插件代码

pkg/scheduler/framework/plugins/

mkdir

k8s.io/api/core/v1k8s.io/apimachinery/pkg/runtimek8s.io/kubernetes/pkg/scheduler/framework

)const

framework.NewStatus(framework.Success)}//

RDMA

nodeInfo.Node().Labels[node.kubernetes.io/rdma-enabled];

!exists

framework.NewStatus(framework.Unschedulable,

Node

framework.NewStatus(framework.Success)

}//

framework.NewStatus(framework.Unschedulable,

Pod

framework.NewStatus(framework.Unschedulable,

注册插件

文件中注册插件

现在dockerhub我不能拉取构建需要的K8S相关镜像所以我这个步骤是在原来的调度镜像上构建自己的调度器镜像

sudo

registry.aliyuncs.com/google_containers/kube-scheduler:v1.22.7

k8s.gcr.io/kube-scheduler:v1.22.7#

Dockerfile

k8s.gcr.io/kube-scheduler:v1.22.7

COPY

/etc/kubernetes/kube-scheduler-config.yamlCMD

[kube-scheduler,

--config/etc/kubernetes/kube-scheduler-config.yaml]上面如果构建不成功说找不到就把文件复制到K8S主目录下

Dockerfile

k8s.gcr.io/kube-scheduler:v1.22.7

COPY

/etc/kubernetes/kube-scheduler-config.yamlCMD

[kube-scheduler,

--config/etc/kubernetes/kube-scheduler-config.yaml]构建镜像
