using its digest **kpod pull [image]@[digest]**. **kpod pull** can be used to pull
images from archives and local storage using different transports.
## imageID
Image stored in local container/storage
## DESTINATION
The DESTINATION is a location to store container images
The Image "DESTINATION" uses a "transport":"details" format.
Multiple transports are supported:
**atomic:**_hostname_**/**_namespace_**/**_stream_**:**_tag_
An image served by an OpenShift(Atomic) Registry server. The current OpenShift project and OpenShift Registry instance are by default read from `$HOME/.kube/config`, which is set e.g. using `(oc login)`.
**dir:**_path_
An existing local directory _path_ storing the manifest, layer tarballs and signatures as individual files. This is a non-standardized format, primarily useful for debugging or noninvasive container inspection.
**docker://**_docker-reference_
An image in a registry implementing the "Docker Registry HTTP API V2". By default, uses the authorization state in `$HOME/.docker/config.json`, which is set e.g. using `(docker login)`.
**docker-archive:**_path_[**:**_docker-reference_]
An image is stored in the `docker save` formatted file. _docker-reference_ is only used when creating such a file, and it must not contain a digest.
**docker-daemon:**_docker-reference_
An image _docker-reference_ stored in the docker daemon internal storage. _docker-reference_ must contain either a tag or a digest. Alternatively, when reading images, the format can also be docker-daemon:algo:digest (an image ID).
**oci:**_path_**:**_tag_
An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
**ostree:**_image_[**@**_/absolute/repo/path_]
An image in local OSTree repository. _/absolute/repo/path_ defaults to _/ostree/repo_.
