% podman(1) podman-push - Push an image from local storage to elsewhere
% Dan Walsh
# podman-push "1" "June 2017" "podman"
## NAME
podman push - Push an image from local storage to elsewhere
## SYNOPSIS
**podman** **push** [*options* [...]] **imageID** [**destination**]
## DESCRIPTION
Pushes an image from local storage to a specified destination.
Push is mainly used to push images to registries, however **podman push**
can be used to save images to tarballs and directories using the following
transports: **dir:**, **docker-archive:**, **docker-daemon:**, **oci-archive:**, and **ostree:**.
## imageID
Image stored in local container/storage
## DESTINATION
The DESTINATION is a location to store container images
The Image "DESTINATION" uses a "transport":"details" format.
If a transport is not given, podman push will attempt to push
to a registry.
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_.
**ostree:**_image_[**@**_/absolute/repo/path_]
An image in local OSTree repository. _/absolute/repo/path_ defaults to _/ostree/repo_.
## OPTIONS
**--authfile**
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`.
**--creds="CREDENTIALS"**
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.
**cert-dir="PATHNAME"**
Pathname of a directory containing TLS certificates and keys.
Default certificates directory is _/etc/containers/certs.d_.
**--compress**
Compress tarball image layers when pushing to a directory using the 'dir' transport. (default is same compression type, compressed or uncompressed, as source)
Note: This flag can only be set when using the **dir** transport
**--format, -f**
Manifest Type (oci, v2s1, or v2s2) to use when pushing an image to a directory using the 'dir:' transport (default is manifest type of source)
Note: This flag can only be set when using the **dir** transport
**--quiet, -q**
When writing the output image, suppress progress output
**--remove-signatures**
Discard any pre-existing signatures in the image
**--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
**--sign-by="KEY"**
Add a signature at the destination using the specified key
**--tls-verify**
Require HTTPS and verify certificates when contacting registries (default: true)
## EXAMPLE
This example extracts the imageID image to a local directory in docker format.
`# podman push imageID dir:/path/to/image`
This example extracts the imageID image to a local directory in oci format.
`# podman push imageID oci-archive:/path/to/layout:image:tag`
This example extracts the imageID image to a container registry named registry.example.com
`# podman push imageID docker://registry.example.com/repository:tag`
This example extracts the imageID image and puts into the local docker container store
`# podman push imageID docker-daemon:image:tag`
This example pushes the alpine image to umohnani/alpine on dockerhub and reads the creds from
the path given to --authfile
```
# podman push --authfile temp-auths/myauths.json alpine docker://docker.io/umohnani/alpine
