kpod-pull - Pull an image from a registry
kpod pull NAME[:TAG|@DIGEST] [--help|-h]
Copies an image from a registry onto the local machine. kpod pull pulls an image from Docker Hub if a registry is not specified in the command line argument. If an image tag is not specified, kpod pull defaults to the image with the latest tag (if it exists) and pulls it. kpod pull can also pull an image using its digest kpod pull [image]@[digest]. kpod pull can be used to pull images from archives and local storage using different transports.
Image stored in local container/storage
The SOURCE is a location to get container images The Image "SOURCE" uses a "transport":"details" format.
Multiple transports are supported:
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 $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 pull NAME[:TAG|@DIGEST]
--authfile
Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json
--cert-dir
Pathname of a directory containing TLS certificates and keys
--creds
Credentials (USERNAME:PASSWORD) to use for authenticating to a registry
--quiet, -q
Suppress output information when pulling images
--signature-policy="PATHNAME"
Pathname of a signature policy file to use. It is not recommended that this option be used, as the default behavior of using the system-wide default policy (frequently /etc/containers/policy.json) is most often preferred
--tls-verify
Require HTTPS and verify certificates when contacting registries (default: true)
