kubernetes 1.12.1版本

      The Kubernetes scheduler is a policy-rich, topology-aware, workload-specific function that significantly impacts availability, performance, and capacity. The scheduler needs to take into account individual and collective resource requirements, quality of service requirements, hardware/software/policy constraints, affinity and anti-affinity specifications, data locality, inter-workload interference, deadlines, and so on. Workload-specific requirements will be exposed through the API as necessary.

      kube-scheduler通过调度算法为待调度Pod列表上的每一个Pod从Node列表中选择一个最合适的Node。

       kube-scheduler当前提供的默认调度流程分为两步

• 预选调度过程：遍历所有目标Node，筛选出符合要求的候选节点
• 确定最优节点：在第一步的基础上，采用优选策略计算出每个候选节点的分数，分数最高者胜出

kube-scheduler启动参数详解

Usage:
  kube-scheduler [flags]

--address string	监听主机IP地址，0.0.0.0监听主机所有主机接口
--algorithm-provider string	设置调度算法，ClusterAutoscalerProvider | DefaultProvider，默认为DefaultProvider
--alsologtostderr	设置true则日志输出到stderr，也输出到日志文件
--config string	配置文件的路径
--kube-api-burst int32	发送到kube-apiserver每秒请求量 （default 100）
--kube-api-content-type string
