--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. 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). (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.

--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)
