## NAME
buildah commit - Create an image from a working container.

## SYNOPSIS
**buildah** **commit** [*options* [...]] **containerID** [**imageName**]

## DESCRIPTION
Writes a new image using the specified container's read-write layer and if it
is based on an image, the layers of that image.  If an image name is not
specified, an ID is assigned, but no name is assigned to the image.

## OPTIONS

**--disable-compression**

Don't compress filesystem layers when building the image.

**--signature-policy**

Pathname of a signature policy file to use.  It is not recommended that this
option be used, as the default behavior of using the system-wide default policy
(frequently */etc/containers/policy.json*) is most often preferred.

**--quiet**

When writing the output image, suppress progress output.

**--format**

Control the format for the image manifest and configuration data.  Recognized
formats include *oci* (OCI image-spec v1.0, the default) and *docker* (version
2, using schema format 2 for the manifest).

**--reference-time**

Sets the creation date in the image to match the last-modified time of the
specified file.  This option is mainly present for use in buildah's self-tests.

## EXAMPLE

buildah commit containerID newImageName
