buildah-commit man page

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, -D
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).
--rm
Remove the container and its content after committing it to an image. Default leaves the container and its content in place.

Example

buildah commit containerID

buildah commit --rm containerID newImageName

buildah commit --disable-compression --signature-policy '/etc/containers/policy.json' containerID

buildah commit --disable-compression --signature-policy '/etc/containers/policy.json' containerID newImageName
