+## NAME
+podman\-push - Push an image from local storage to elsewhere
+
+## SYNOPSIS
+**podman push** [*options*] *image* [*destination*]
+
+**podman image push** [*options*] *image* [*destination*]
+
+## DESCRIPTION
+Pushes an image 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:**.
+
+## imageID
+Image stored in local container/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.
+
+  **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)`.
+
+  **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.
+
+  **docker-daemon:**_docker-reference_
+  An image _docker-reference_ stored in the docker daemon internal storage.  _docker-reference_ must contain either a tag or a digest.  Alternatively, when reading images, the format can also be docker-daemon:algo:digest (an image ID).
+
+  **oci-archive:**_path_**:**_tag_
+  An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
+
+## 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`. (Not available for remote commands)
+
+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)
+
+**--format**, **-f**=*format*
+
+Manifest Type (oci, v2s1, or v2s2) to use when pushing an image to a directory using the 'dir:' transport (default is manifest type of source)
+Note: This flag can only be set when using the **dir** transport
+
+**--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
+
+**--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. (Not available for remote commands)
+
+## 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
