The +Kubernetes version 1.8 introduces local ephemeral storage resource. The management of local ephemeral storage is very similar to memory resource. +Each Container of a Pod can specify one or more of the following: + +* `spec.containers[].resources.limits.ephemeral-storage` +* `spec.containers[].resources.requests.ephemeral-storage` + +Limits and requests for `ephemeral-storage` are measured in bytes. You can express storage as +a plain integer or as a fixed-point integer using one of these suffixes: +E, P, T, G, M, K. You can also use the power-of-two equivalents: Ei, Pi, Ti, Gi, +Mi, Ki. For example, the following represent roughly the same value: + +```shell +128974848, 129e6, 129M, 123Mi +``` + +Here's an example. +The following Pod has two Containers. Each one has a request of 2GiB of local ephemeral storage. Each Container has a limit of 4GiB of local ephemeral storage. You can say the Pod has a request of 4GiB of local ephemeral storage, and a limit of 8GiB of storage. + +```yaml +apiVersion: v1 +kind: Pod +metadata: + name: frontend +spec: + containers: + - name: db + image: mysql + resources: + requests: + ephemeral-storage: "2Gi" + limits: + ephemeral-storage: "4Gi" + - name: wp + image: wordpress + resources: + requests: + ephemeral-storage: "2Gi" + limits: + ephemeral-storage: "4Gi" +``` + + ## Opaque integer resources (Alpha feature) Kubernetes version 1.5 introduces Opaque integer resources.
