Fix man page to document podman push --format fully. Also found that push was not handling the tlsverify so fixed this. Signed-off-by: Daniel J Walsh <dwalsh@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
|
|
|
|
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
