By default, uses the authorization state in `$XDG_RUNTIME_DIR/containers/auth.json`, which is set e.g. using `(kpod 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-archive:**_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_. + +**kpod [GLOBAL OPTIONS]** + +**kpod pull [GLOBAL OPTIONS]** + +**kpod pull NAME[:TAG|@DIGEST]** + +## OPTIONS + +**--authfile** + +Path of the authentication file.
