buildah from - Creates a new working container, either from scratch or using a specified image as a starting point.
buildah from [options [...]] imageName
Creates a working container based upon the specified image name. If the supplied image name is "scratch" a new empty container is created.
The container ID of the container that was created. On error, -1 is returned and errno is returned.
--name name
A name for the working container
--pull
Pull the image if it is not present. If this flag is disabled (with --pull=false) and the image is not present, the image will not be pulled. Defaults to true.
--pull-always
Pull the image even if a version of the image is already present.
--transport transport
A prefix to prepend to the image name in order to pull the image. The default value is "docker://". Note that no separator is implicitly added when the values are combined.
--signature-policy signaturepolicy
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
If an image needs to be pulled from the registry, suppress progress output.
