 A size limit can be specified for the default medium, which limits the capacity
 of the `emptyDir` volume. The storage is allocated from [node ephemeral
 storage](/docs/concepts/configuration/manage-resources-containers/#setting-requests-and-limits-for-local-ephemeral-storage).
 If that is filled up from another source (for example, log files or image
 overlays), the `emptyDir` may run out of capacity before this limit.
