podman-push - Man Page

Push an image, manifest list or image index from local storage to elsewhere

Synopsis

podman push [options] image [destination]

podman image push [options] image [destination]

Description

Pushes an image, manifest list or image index 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: and oci-archive:.

Image storage

Images are pushed from those stored in local image 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.

$ podman push myimage dir:/tmp/myimage

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).

$ podman push myimage 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 push myimage docker-archive:/tmp/myimage

docker-daemon:docker-reference
 An image in docker-reference format stored in the docker daemon internal storage. docker-reference must contain a tag.

$ sudo podman push myimage 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 push myimage oci-archive:/tmp/myimage

Options

--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

--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.

--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)

--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

--digestfile Digestfile

After copying the image, write the digest of the resulting image to the file.  (Not available for remote commands)

--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.

--format, -f=format

Manifest Type (oci, v2s2, or v2s1) to use when pushing an image.

--quiet, -q

When writing the output image, suppress progress output

--remove-signatures

Discard any pre-existing signatures in the image. (Not available for remote commands)

--sign-by=key

Add a signature at the destination using the specified key. (Not available for remote commands)

--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.

Example

This example pushes the image specified by the imageID to a local directory in docker format.

# podman push imageID dir:/path/to/image

This example pushes the image specified by the imageID to a local directory in oci format.

# podman push imageID oci-archive:/path/to/layout:image:tag

This example pushes the image specified by the imageID to a container registry named registry.example.com

# podman push imageID docker://registry.example.com/repository:tag

This example pushes the image specified by the imageID to a container registry named registry.example.com and saves the digest in the specified digestfile.

# podman push --digestfile=/tmp/mydigest imageID docker://registry.example.com/repository:tag

This example pushes the image specified by the imageID and puts it 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
