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 `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using `(podman login)`. If the authorization state is not found there, `$HOME/.docker/config.json` is checked, which is set 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-archive:**_path_**:**_tag_ + An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_. + +## OPTIONS + +**--authfile**=*path* + +Path of the authentication file. Default is ${XDG\_RUNTIME\_DIR}/containers/auth.json, which is set using `podman login`. +If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using `docker login`.

The password is entered without echo. + +**--cert-dir**=*path* + +Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry. +Default certificates directory is _/etc/containers/certs.d_. (Not available for remote commands) + +**--compress** + +Compress tarball image layers when pushing to a directory using the 'dir' transport. (default is same compression type, compressed or uncompressed, as source) +Note: This flag can only be set when using the **dir** transport + +**--digestfile** *Digestfile* + +After copying the image, write the digest of the resulting image to the file.
