Phase（阶段） 已弃⽤，Node phase不再使⽤。 Condition（状况） conditions 字段描述所有 Running Node的状态。 Node Condition Description OutOfDisk 如果节点没有⾜够的可⽤空间来添加新的Pod，则为 True ，否则为 False Ready 如果节点健康并准备好接受Pod，则为 True ；如果节点不健康且不接受Pod，则 集群管理员应为每个映射创建⼀个PriorityClass对象。 25-Pod优先级和抢占 111 PriorityClass还有两个可选字段： globalDefault 和 description 。对于未设置 PriorityClassName 的Pod， globalDefault 字段表示该PriorityClass的值。只有⼀个 globalDefault=true 的PriorityClass能够存在于系统中。如果 没有设置了 globalDefault 的PriorityClass，那么，未设置 PriorityClassName 的Pod的优先级为零。 description 字段是⼀个任意字符串。这是为了告诉集群⽤户，他们什么时候该使⽤这个PriorityClass。 注1 ：如果升级现有集群并启⽤此功能，则现有Pod的优先级为零。 注2 ：为Pod动态添加

patterns of Kubernetes (Controller, codegen etc) • Write your own Controller • gPRC based interface design in Kubernetes (CRI as example) • For Kubernetes users: • Effective pattern of programming com/kubernetes/gengo • github.com/kubernetes/kubernetes/tree/master/cmd/libs/go2idl Pattern 3: gRPC based Interface • Decouple Kubernetes from external dependencies • kubelet -> gRPC -> dockershim -> dockerd with CRD 4.code gen for deep copy, API conversion, API doc, encoding/decoding etc 5.gRPC based interface (e.g. CRI) 2.How we can do better to use Kubernetes? 1.Programming Patterns in Kubernetes
