% kpod(1) kpod-pull - Simple tool to pull an image from a registry
% Urvashi Mohnani
# kpod-pull "1" "July 2017" "kpod"
## NAME
kpod-pull - Pull an image from a registry
## SYNOPSIS
**kpod pull**
**NAME[:TAG|@DIGEST]**
[**--help**|**-h**]
## DESCRIPTION
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.
## imageID
Image stored in local container/storage
## SOURCE
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 `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using `(kpod login)`. If the authorization state is not found there, `$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_.
**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. Default is ${XDG_RUNTIME\_DIR}/containers/auth.json, which is set using `kpod login`.
If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using `docker login`.
**--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)
