Followup to #14906, in which a nonexistent option was found in a man page. The xref script was designed to catch that, but I was too lax in my parsing: the option was documented using wrong syntax, and the script didn't catch it. Solution: do not allow *any* unrecognized cruft in the option description lines. And fix all improperly-written entries to conform to the rule: **--option**=*value(s)* Two asterisks around option, which must have two dashes. One asterisk around value(s). This is going to cause headaches for some people adding new options, but I don't think I can fix that: there are many factors that make an unparseable line. Adding 'hint' code would make the script even more complex than it is. I have to assume that our contributors are smart enough to look at surrounding context and figure out the right way to specify options. Signed-off-by: Ed Santiago <santiago@redhat.com>

## 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. 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
|
|
|
|
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, 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`
|
|
|
|
#### **--cert-dir**=*path*
|
|
|
|
Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry. (Default: /etc/containers/certs.d)
|
|
Please refer to containers-certs.d(5) for details. (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`.
|
|
|
|
#### **--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.
|
|
|
|
#### **--digestfile**=*Digestfile*
|
|
|
|
After copying the image, write the digest of the resulting image to the file. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
|
|
|
|
#### **--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.
|
|
|
|
#### **--sign-by**=*key*
|
|
|
|
Add a 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)
|
|
|
|
#### **--tls-verify**
|
|
|
|
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
