## SYNOPSIS
|
|
**podman import** [*options*] *path* [*reference*]
|
|

**podman image import** [*options*] *path* [*reference*]

## DESCRIPTION
|
|
**podman import** imports a tarball (.tar, .tar.gz, .tgz)
|
|
and saves it as a filesystem image. Remote tarballs can be specified using a URL.

Various image instructions can be configured with the **--change** flag and
|
|
a commit message can be set using the **--message** flag.

|
**reference**, if present, is a tag to assign to the image.
