+To make the resource quota work on ephemeral-storage, two things need to be done:
+
+* An admin sets the resource quota for ephemeral-storage in a namespace.
+* A user needs to specify limits for the ephemeral-storage resource in the Pod spec.
+
+If the user doesn't specify the ephemeral-storage resource limit in the Pod spec,
+the resource quota is not enforced on ephemeral-storage.

+为了使临时性存储的资源配额生效，需要完成以下两个步骤：
+
+* 管理员在命名空间中设置临时性存储的资源配额。
+* 用户需要在 Pod spec 中指定临时性存储资源的限制。
+
+如果用户在 Pod spec 中未指定临时性存储资源的限制，
+则临时性存储的资源配额不会生效。

 Kubernetes 允许你跟踪、预留和限制 Pod
 可消耗的临时性本地存储数量。
