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. + +## 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 `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using `(podman login)`. If the authorization state is not found there, `$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 + +**--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. + +**--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`. (Not available for remote commands) + +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_. (Not available for remote commands) + +**--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. + +**--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.
