Namespaces are used to organize objects in a cluster and provide a way to divide cluster resources. Names of resources need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects _(e.g. Deployments, Services, etc)_ and not for cluster-wide objects _(e.g. StorageClass, Nodes, PersistentVolumes, etc)_.

名字空间用来组织集群中对象，并为集群资源划分提供了一种方法。
|
|||
同一名字空间内的资源名称必须唯一，但跨名字空间时不作要求。
|
||||
基于名字空间的作用域限定仅适用于名字空间作用域的对象（例如 Deployment、Services 等），
|
||||
而不适用于集群作用域的对象（例如 StorageClass、Node、PersistentVolume 等）。
|
||||
|
|
在一些文档里名字空间也称为命名空间。
