podman-push(1)

NAME
podman-push - 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.

Image storage
Images are pushed from those stored in local image storage.

DESTINATION
DESTINATION is the location the container image is pushed to. It supports all transports from containers-transports(5). If no transport is specified, the docker (i.e., container registry) transport is used. For remote clients, including Mac and Windows (excluding WSL2) machines, docker is the only supported transport.
    # Push to a container registry
    $ podman push quay.io/podman/stable
    # Push to a container registry via the docker transport
    $ podman push docker://quay.io/podman/stable
    # Push to a container registry with another tag
    $ podman push myimage quay.io/username/myimage
    # Push to a local directory
    $ podman push myimage dir:/tmp/myimage
    # Push to a tarball in the docker-archive format
    $ podman push myimage docker-archive:/tmp/myimage
    # Push to a local docker daemon
    $ sudo podman push myimage docker-daemon:docker.io/library/myimage:33
    # Push to a tarball in the OCI format
    $ podman push myimage oci-archive:/tmp/myimage

OPTIONS

  --authfile=path
Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json on Linux, and $HOME/.config/containers/auth.json on Windows/macOS. The file is created by podman login(podman-login.1.md). If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using docker login.

Note: There is also the option to override the default path of the authentication file by setting the REGISTRY_AUTH_FILE environment variable. This can be done with 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) For details, see containers-certs.d(5) ⟨https://github.com/containers/image/blob/main/docs/containers-certs.d.5.md⟩. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

  --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

  --compression-format=gzip | zstd | zstd:chunked
Specifies the compression format to use. Supported values are: gzip, zstd and zstd:chunked. The default is gzip unless overridden in the containers.conf file. zstd:chunked is incompatible with encrypting images, and will be treated as zstd with a warning in that case.

  --compression-level=level
Specifies the compression level to use. The value is specific to the compression algorithm used, e.g. for zstd the accepted values are in the range 1-20 (inclusive) with a default of 3, while for gzip it is 1-9 (inclusive) and has a default of 5.

  --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 appears and the value can be entered. The password is entered without echo.

Note that the specified credentials are only used to authenticate against target registries. They are not used for mirrors or when the registry gets rewritten (see containers-registries.conf(5)); to authenticate against those consider using a containers-auth.json(5) file.

  --digestfile=Digestfile
After copying the image, write the digest of the resulting image to the file.

  --disable-content-trust
This is a Docker-specific option to disable image verification to a container registry and is not supported by Podman. This option is a NOOP and provided solely for scripting compatibility.

  --encrypt-layer=layer(s)
Layer(s) to encrypt: 0-indexed layer indices with support for negative indexing (e.g. 0 is the first layer, -1 is the last layer). If not defined, encrypts all layers if encryption-key flag is specified.

  --encryption-key=key
The [protocol:keyfile] specifies the encryption protocol, which can be JWE (RFC7516), PGP (RFC4880), and PKCS7 (RFC2315) and the key material required for image encryption. For instance, jwe:/path/to/key.pem or pgp:admin@example.com or pkcs7:/path/to/x509-file.

  --force-compression
If set, push uses the specified compression algorithm even if the destination contains a differently-compressed variant already. Defaults to true if --compression-format is explicitly specified on the command-line, false otherwise.

  --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.

  --retry=attempts
Number of times to retry pulling or pushing images between the registry and local storage in case of failure. Default is 3.

  --retry-delay=duration
Duration of delay between retry attempts when pulling or pushing images between the registry and local storage in case of failure. The default is to start at two seconds and then exponentially back off. The delay is used when this value is set, and no exponential back off occurs.

  --sign-by=key
Add a “simple signing” signature at the destination using the specified key. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

  --sign-by-sigstore=param-file
Add a sigstore signature based on further options specified in a container's sigstore signing parameter file param-file. See containers-sigstore-signing-params.yaml(5) for details about the file format.

  --sign-by-sigstore-private-key=path
Add a sigstore signature at the destination using a private key at the specified path. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

  --sign-passphrase-file=path
If signing the image (using either --sign-by or --sign-by-sigstore-private-key), read the passphrase to use from the specified path.

  --tls-verify
Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true, TLS verification is used. If set to false, TLS verification is not used. If not specified, TLS verification is used unless the target registry is listed as an insecure registry in containers-registries.conf(5) ⟨https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md⟩

EXAMPLE
Push the specified image to a local directory:
    # podman push imageID dir:/path/to/image

Push the specified image to a local directory in OCI format:
    # podman push imageID oci-archive:/path/to/layout:image:tag

Push the specified image to a container registry:
    # podman push imageID docker://registry.example.com/repository:tag

Push the specified image to a container registry and save the digest in the specified file:
    # podman push --digestfile=/tmp/mydigest imageID docker://registry.example.com/repository:tag

Push the specified image into the local Docker daemon container store:
    # podman push imageID docker-daemon:image:tag

Push the specified image with a different image name using credentials from an alternate authfile path:
    # podman push --authfile temp-auths/myauths.json alpine docker://docker.io/umohnani/alpine
