Kubernetes 的用户交互 API

用户可以向 kubernetes 提交各种类型的任务和数据,我们把 kubernetes 接受的任务或数据类型称为 API。经过这几年的飞速发展,API 的种类非常丰富。

最常见的 API:conceptstasks

API 完整列表:api-index

在 kubernetes 项目中,API 的定义代码位于 staging/src/k8s.io/api,staging/src/k8s.io/api 已经作为独立项目发布,通过 k8s.io/api 引用。

API 的版本与作用域

Resource 是有版本的:

apiVersion: v1
kind: Namespace
...
apiVersion: extensions/v1beta1
kind: DaemonSet

有一些 resource 是 cluster 级别的,不属于任何 namespace,全局有效,后面的 cluster apis。
