.nh .TH podman-push 1 .SH NAME .PP podman-push - Push an image, manifest list or image index from local storage to elsewhere .SH SYNOPSIS .PP \fBpodman push\fP [\fIoptions\fP] \fIimage\fP [\fIdestination\fP] .PP \fBpodman image push\fP [\fIoptions\fP] \fIimage\fP [\fIdestination\fP] .SH DESCRIPTION .PP Pushes an image, manifest list or image index from local storage to a specified destination. .SH Image storage .PP Images are pushed from those stored in local image storage. .SH DESTINATION .PP DESTINATION is the location the container image is pushed to. It supports all transports from \fBcontainers-transports(5)\fR\&. If no transport is specified, the \fBdocker\fR (i.e., container registry) transport is used. For remote clients, including Mac and Windows (excluding WSL2) machines, \fBdocker\fR is the only supported transport. .EX # 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 .EE .SH OPTIONS .SS \fB--authfile\fP=\fIpath\fP .PP Path of the authentication file. Default is \fB${XDG_RUNTIME_DIR}/containers/auth.json\fR on Linux, and \fB$HOME/.config/containers/auth.json\fR on Windows/macOS. The file is created by \fBpodman login\fP\&. If the authorization state is not found there, \fB$HOME/.docker/config.json\fR is checked, which is set using \fBdocker login\fP\&. .PP Note: There is also the option to override the default path of the authentication file by setting the \fBREGISTRY_AUTH_FILE\fR environment variable. This can be done with \fBexport REGISTRY_AUTH_FILE=\fIpath\fP\fP\&. .SS \fB--cert-dir\fP=\fIpath\fP .PP Use certificates at \fIpath\fP (*\&.crt, *\&.cert, *\&.key) to connect to the registry. (Default: /etc/containers/certs.d) For details, see \fBcontainers-certs.d(5)\fP\&. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines) .SS \fB--compress\fP .PP Compress tarball image layers when pushing to a directory using the 'dir' transport. (default is same compression type, compressed or uncompressed, as source) .PP Note: This flag can only be set when using the \fBdir\fP transport .SS \fB--compression-format\fP=\fBgzip\fP | \fIzstd\fP | \fIzstd:chunked\fP .PP Specifies the compression format to use. Supported values are: \fBgzip\fR, \fBzstd\fR and \fBzstd:chunked\fR\&. The default is \fBgzip\fR unless overridden in the containers.conf file. .SS \fB--compression-level\fP=\fIlevel\fP .PP 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. .SS \fB--creds\fP=\fI[username[:password]]\fP .PP 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. .PP 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 \fBcontainers-registries.conf(5)\fR); to authenticate against those consider using a \fBcontainers-auth.json(5)\fR file. .SS \fB--digestfile\fP=\fIDigestfile\fP .PP After copying the image, write the digest of the resulting image to the file. .SS \fB--disable-content-trust\fP .PP 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. .SS \fB--encrypt-layer\fP=\fIlayer(s)\fP .PP 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. .SS \fB--encryption-key\fP=\fIkey\fP .PP 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. .SS \fB--force-compression\fP .PP If set, push uses the specified compression algorithm even if the destination contains a differently-compressed variant already. Defaults to \fBtrue\fR if \fB--compression-format\fR is explicitly specified on the command-line, \fBfalse\fR otherwise. .SS \fB--format\fP, \fB-f\fP=\fIformat\fP .PP Manifest Type (oci, v2s2, or v2s1) to use when pushing an image. .SS \fB--quiet\fP, \fB-q\fP .PP When writing the output image, suppress progress output .SS \fB--remove-signatures\fP .PP Discard any pre-existing signatures in the image. .SS \fB--sign-by\fP=\fIkey\fP .PP 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) .SS \fB--sign-by-sigstore\fP=*param-file*** .PP Add a sigstore signature based on further options specified in a container's sigstore signing parameter file \fIparam-file\fP\&. See containers-sigstore-signing-params.yaml(5) for details about the file format. .SS \fB--sign-by-sigstore-private-key\fP=\fIpath\fP .PP 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) .SS \fB--sign-passphrase-file\fP=\fIpath\fP .PP If signing the image (using either \fB--sign-by\fP or \fB--sign-by-sigstore-private-key\fP), read the passphrase to use from the specified path. .SS \fB--tls-verify\fP .PP Require HTTPS and verify certificates when contacting registries (default: \fBtrue\fP). If explicitly set to \fBtrue\fP, TLS verification is used. If set to \fBfalse\fP, TLS verification is not used. If not specified, TLS verification is used unless the target registry is listed as an insecure registry in \fBcontainers-registries.conf(5)\fP .SH EXAMPLE .PP This example pushes the image specified by the imageID to a local directory in docker format. .PP \fB# podman push imageID dir:/path/to/image\fR .PP This example pushes the image specified by the imageID to a local directory in oci format. .PP \fB# podman push imageID oci-archive:/path/to/layout:image:tag\fR .PP This example pushes the image specified by the imageID to a container registry named registry.example.com .PP \fB# podman push imageID docker://registry.example.com/repository:tag\fR .PP 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. .PP \fB# podman push --digestfile=/tmp/mydigest imageID docker://registry.example.com/repository:tag\fR .PP This example pushes the image specified by the imageID and puts it into the local docker container store .PP \fB# podman push imageID docker-daemon:image:tag\fR .PP This example pushes the alpine image to umohnani/alpine on dockerhub and reads the creds from the path given to --authfile .EX # podman push --authfile temp-auths/myauths.json alpine docker://docker.io/umohnani/alpine Getting image source signatures Copying blob sha256:5bef08742407efd622d243692b79ba0055383bbce12900324f75e56f589aedb0 4.03 MB / 4.03 MB [========================================================] 1s Copying config sha256:ad4686094d8f0186ec8249fc4917b71faa2c1030d7b5a025c29f26e19d95c156 1.41 KB / 1.41 KB [========================================================] 1s Writing manifest to image destination Storing signatures .EE .PP This example pushes the rhel7 image to rhel7-dir with the "oci" manifest type .EX # podman push --format oci registry.access.redhat.com/rhel7 dir:rhel7-dir Getting image source signatures Copying blob sha256:9cadd93b16ff2a0c51ac967ea2abfadfac50cfa3af8b5bf983d89b8f8647f3e4 71.41 MB / 71.41 MB [======================================================] 9s Copying blob sha256:4aa565ad8b7a87248163ce7dba1dd3894821aac97e846b932ff6b8ef9a8a508a 1.21 KB / 1.21 KB [========================================================] 0s Copying config sha256:f1b09a81455c351eaa484b61aacd048ab613c08e4c5d1da80c4c46301b03cf3b 3.01 KB / 3.01 KB [========================================================] 0s Writing manifest to image destination Storing signatures .EE .SH SEE ALSO .PP \fBpodman(1)\fP, \fBpodman-pull(1)\fP, \fBpodman-login(1)\fP, \fBcontainers-certs.d(5)\fP, \fBcontainers-registries.conf(5)\fP, \fBcontainers-transports(5)\fP
