kube-scheduler 负责分配调度 Pod 到集群内的节点上,它监听 kube-apiserver,查询还未分配 Node 的 Pod,然后根据调度策略为这些 Pod 分配节点(更新 Pod 的NodeName 字段)。 调度器需要充分考虑诸多的因素: 公平调度 资源高效利用 QoS affinity 和anti-affinity 数据本地化 内部负载干扰 deadlines 指定Node 节点调度 ...

Node Affinity Node affinities provide an expressive language you can use to define which nodes to run a pod on. You can define: Exact matches using the AND operator Soft rules indicating a preference for a certain type of node, but allowing the Scheduler to deploy a pod even if the constra...

PV(注 9)加入了PersistentVolume.Spec.NodeAffinity字段,其中应包含本地节点的主机名。 StorageClass(注 10)新增了StorageClass.volumeBindingMode: WaitForFirstConsumer选项,要求 Kubernetes 等到 Pod 和 PV 成功完成调度规划之后才进行绑定。 在Kubernetes 集群中使用 Navigator 管理Cassandra数据库(注 11)就使用这一特性...
