## NAME
podman\-pull - Pull an image from a registry
## SYNOPSIS
**podman pull** [*options*] *source* [*source*...]
**podman image pull** [*options*] *source* [*source*...]
**podman pull** [*options*] [*transport*]*name*[:*tag*|@*digest*]
**podman image pull** [*options*] [*transport*]*name*[:*tag*|@*digest*]
## DESCRIPTION
podman pull copies an image from a registry onto the local machine. The command can pull one or more images. If the image reference in the command line argument does not contain a registry, it is referred to as a`short-name` reference. If the image is a 'short-name' reference, Podman will prompt the user for the specific container registry to pull the image from, if an alias for the short-name has not been specified in the `short-name-aliases.conf`. 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 images using a digest **podman pull** *image*@*digest* and can also be used to pull images from archives and local storage using different transports.
*IMPORTANT: Images are stored in local image storage.*
## SOURCE
SOURCE is the location from the container image is pulled from. It supports all transports from **[containers-transports(5)](https://github.com/containers/image/blob/main/docs/containers-transports.5.md)**. If no transport is specified, the input is subject to short-name resolution and the `docker` (i.e., container registry) transport is used. For remote clients, `docker` is the only supported transport.
```
# Pull from a container registry
$ podman pull quay.io/username/myimage
# Pull from a container registry with short-name resolution
$ podman pull fedora
# Pull from a container registry via the docker transport
$ podman pull docker://quay.io/username/myimage
# Pull from a local directory
$ podman pull dir:/tmp/myimage
# Pull from a tarball in the docker-archive format
$ podman pull docker-archive:/tmp/myimage
# Pull from a local docker daemon
$ sudo podman pull docker-daemon:docker.io/library/myimage:33
# Pull from a tarball in the OCI-archive format
$ podman pull oci-archive:/tmp/myimage
```
## OPTIONS
#### **--all-tags**
All tagged images in the repository will be pulled.
*IMPORTANT: When using the all-tags flag, Podman will not iterate over the search registries in the **[containers-registries.conf(5)](https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md)** 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. If the authorization state is not found there, `$HOME/.docker/config.json` is checked, which is set using `docker login`.
Default is `${XDG\_RUNTIME\_DIR}/containers/auth.json`, which is set using `podman login`.
*IMPORTANT: The default path of the authentication file can be overwritten 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: /etc/containers/certs.d)
Please refer to **[containers-certs.d(5)](https://github.com/containers/image/blob/main/docs/containers-certs.d.5.md)** for details. (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 the 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. The `--platform` option can be used to override the current architecture and operating system.
*IMPORTANT: Conflicts with --arch and --os*
#### **--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
**short-name-aliases.conf** (`/var/cache/containers/short-name-aliases.conf`, `$HOME/.cache/containers/short-name-aliases.conf`)
When users specify images that do not include the container registry where the
image is stored, this is called a short name. The use of unqualified-search registries entails an ambiguity as it is unclear from which registry a given image, referenced by a short name, may be pulled from.
Using short names is subject to the risk of hitting squatted registry namespaces. If the unqualified-search registries are set to ["public-registry.com", "my-private-registry.com"] an attacker may take over a namespace of `public-registry.com` such that an image may be pulled from `public-registry.com` instead of the intended source `my-private-registry.com`.
While it is highly recommended to always use fully-qualified image references, existing deployments using short names may not be easily changed. To circumvent the aforementioned ambiguity, so called short-name aliases can be configured that point to a fully-qualified image reference. Distributions often ship a default shortnames.conf expansion file in /etc/containers/registries.conf.d/ directory. Administrators can use this directory to add their own local short-name expansion files.
When pulling an image, if the user does not specify the complete registry, container engines attempt to expand the short-name into a full name. If the command is executed with a tty, the user will be prompted to select a registry from the
default list unqualified registries defined in registries.conf. The user's selection is then stored in a cache file to be used in all future short-name expansions. Rootfull short-names are stored in /var/cache/containers/short-name-aliases.conf. Rootless short-names are stored in the $HOME/.cache/containers/short-name-aliases.conf file.
For more information on short-names, see `containers-registries.conf(5)`
**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`.
## EXAMPLES
Pull a single image with short name resolution.
