--------------------------------
Issue Type: Bug (was: Sub-task)
Parent: (was: MESOS-2540)
> mesos containerizer should allow for container images to specify dependent
> layers
> ---------------------------------------------------------------------------------

> Key: MESOS-2544
> URL: https://issues.apache.org/jira/browse/MESOS-2544
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Reporter: Jay Buffington
>
> In order to get better cache-hit rates we should allow for stacked container
> image layers. The image archive format is the format the image is hosted in.
> Examples include docker image format [1] and ACI [2]. Whatever the archive
> format, it needs to allow for referencing dependent layers.
> The mesos slave needs to pull down the image and its dependent layers and
> convert it to a image runtime format. This format could be hard links,
> overlayfs[3] or take advantage of device mapper or btrfs features.
