## NAME
podman\-pull - Pull an image from a registry
## SYNOPSIS
**podman pull** [*options*] *source*
**podman image pull** [*options*] *source*
**podman pull** [*options*] [*transport*]*name*[:*tag*|@*digest*]
**podman image pull** [*options*] [*transport*]*name*[:*tag*|@*digest*]
## DESCRIPTION
Copies an image from a registry onto the local machine. **podman 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, **podman pull** defaults to the image with the
**latest** tag (if it exists) and pulls it. After the image is pulled, podman will
print the full image ID. **podman pull** can also pull an image
using its digest **podman pull** *image*@*digest*. **podman pull** can be used to pull
images from archives and local storage using different transports.
## Image storage
Images are stored in local image storage.
## SOURCE
The SOURCE is the location from which the container images are pulled.
The Image "SOURCE" uses a "transport":"details" format. Only the `docker` (container registry)
transport is allowed for remote access.
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.
$ podman pull dir:/tmp/myimage
**docker://**_docker-reference_ (Default)
An image reference stored in a remote container image registry. The reference can include a path to a
specific registry; if it does not, the registries listed in registries.conf will be queried to find a matching
image. By default, credentials from podman login (stored at $XDG_RUNTIME_DIR/containers/auth.json by default)
will be used to authenticate; if these cannot be found, we will fall back to using credentials in
$HOME/.docker/config.json.
$ podman pull quay.io/username/myimage
**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.
$ podman pull docker-archive:/tmp/myimage
**docker-daemon:**_docker-reference_
An image in _docker-reference_ format stored in the docker daemon internal storage. The _docker-reference_ can also be an image ID (docker-daemon:algo:digest).
$ sudo podman pull docker-daemon:docker.io/library/myimage:33
**oci-archive:**_path_**:**_tag_
An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
$ podman pull oci-archive:/tmp/myimage
## OPTIONS
#### **\-\-all-tags**, **a**
All tagged images in the repository will be pulled.
Note: When using the all-tags flag, Podman will not iterate over the search registries in the containers-registries.conf(5) but will always use docker.io for unqualified image names.
#### **\-\-arch**=*ARCH*
Override the architecture, defaults to hosts, of the image to be pulled. For example, `arm`.
#### **\-\-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`.
Note: You can also override the default path of the authentication file by setting the REGISTRY\_AUTH\_FILE
environment variable. `export REGISTRY_AUTH_FILE=path`
#### **\-\-cert-dir**=*path*
Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry.
Default certificates directory is _/etc/containers/certs.d_. (This option is not available with the remote Podman client)
#### **\-\-creds**=*[username[:password]]*
The [username[:password]] to use to authenticate with the registry if required.
If one or both values are not supplied, a command line prompt will appear and the
value can be entered. The password is entered without echo.
#### **\-\-disable-content-trust**
This is a Docker specific option to disable image verification to a Docker
registry and is not supported by Podman. This flag is a NOOP and provided
solely for scripting compatibility.
#### **\-\-help**, **-h**
Print usage statement
#### **\-\-os**=*OS*
Override the OS, defaults to hosts, of the image to be pulled. For example, `windows`.
#### **\-\-platform**=*OS/ARCH*
Specify the platform for selecting the image. (Conflicts with --arch and --os)
The `--platform` option can be used to override the current architecture and operating system.
#### **\-\-quiet**, **-q**
Suppress output information when pulling images
#### **\-\-tls-verify**=*true|false*
Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true,
then TLS verification will be used. If set to false, then TLS verification will not be used. If not specified,
TLS verification will be used unless the target registry is listed as an insecure registry in registries.conf.
#### **\-\-variant**=*VARIANT*
Use _VARIANT_ instead of the default architecture variant of the container image. Some images can use multiple variants of the arm architectures, such as arm/v5 and arm/v7.

## FILES
**registries.conf** (`/etc/containers/registries.conf`)
registries.conf is the configuration file which specifies which container registries should be consulted when completing image names which do not include a registry or domain portion.
NOTE: Use the environment variable `TMPDIR` to change the temporary storage location of downloaded container images. Podman defaults to use `/var/tmp`.
