## NAME
podman\-commit - Create new image based on the changed container
## SYNOPSIS
**podman commit** [*options*] *container* [*image*]
**podman container commit** [*options*] *container* [*image*]
## DESCRIPTION
**podman commit** creates an image based on a changed container. The author of the
image can be set using the `--author` flag. Various image instructions can be
configured with the `--change` flag and a commit message can be set using the
`--message` flag. The container and its processes are paused while the image is
committed. This minimizes the likelihood of data corruption when creating the new
image. If this is not desired, the `--pause` flag can be set to false. When the commit
is complete, Podman will print out the ID of the new image.
If *image* does not begin with a registry name component, `localhost` will be added to the name.
If *image* is not provided, the values for the `REPOSITORY` and `TAG` values of the created image will each be set to `<none>`.
## OPTIONS
**--author**, **-a**=*author*
Set the author for the committed image
**--change**, **-c**=*instruction*
Apply the following possible instructions to the created image:
**CMD** | **ENTRYPOINT** | **ENV** | **EXPOSE** | **LABEL** | **ONBUILD** | **STOPSIGNAL** | **USER** | **VOLUME** | **WORKDIR**
Can be set multiple times
**--format**, **-f**=*format*
Set the format of the image manifest and metadata. The currently supported formats are _oci_ and _docker_. If
not specifically set, the default format used is _oci_.
**--iidfile**=*ImageIDfile*
Write the image ID to the file.
**--include-volumes**
Include in the committed image any volumes added to the container by the `--volume` or `--mount` options to the `podman create` and `podman run` commands.
**--message**, **-m**=*message*
Set commit message for committed image. The message field is not supported in _oci_ format.
**--pause**, **-p**
Pause the container when creating an image
**--quiet**, **-q**
Suppress output
