to Nodes（将Pod分配到Node） 您可以约束⼀个 pod ，让其只能在特定 nodes 上运⾏，或者更倾向于在特定Node上运⾏。有⼏种⽅法能做到这点，他 们都使⽤ label selectors 进⾏选择。通常这种约束不是必要的，因为Scheduler会⾃动执⾏合理的放置（例如：在Node 之间传播您的Pod，⽽不是将Pod放在⼀个没有⾜够资源的Node上等），但在某些情况下，您可能需要控制⼀个Pod落 版本中更改该Pod所暴露的端⼝，⽽不会影响客户端的调⽤。 Kubernetes Service ⽀持 TCP 和 UDP 协议。 默认值为 TCP 。 Services without selectors（不带选择器的Service） Service通常抽象了 Pod 的访问，但也可抽象其他类型的后端。 例如： 26-Service 115 您希望在⽣产环境中使⽤外部数据库集群，但在测试中，您将使⽤⾃⼰的数据库。 如何⾃动配置DNS，取决于Service是否定义了选择器。 With selectors（有选择器） 对于定义了选择器的Headless Services，Endpoint Controller会在API中创建 Endpoint 记录，并修改DNS配置以返 回 Pods A记录（地址），A记录直接指向Service后端的Pod。 Without selectors（⽆选择器） 对于没有选择器的Headless

slicers You can slice a MultiIndex by providing multiple indexers. You can provide any of the selectors as if you are indexing by label, see Selection by Label, including slices, lists of labels, labels of the table with specified internal CSS. Although table styles allow the flexibility to add CSS selectors and properties controlling all individual parts of the table, they are unwieldy for individual cell functionality. The :hover pseudo-selector, as well as other pseudo-selectors, can only be used this way. To replicate the normal format of CSS selectors and properties (attribute value pairs), e.g. tr:hover {
