images – Image metadata¶

This module provides classes for manipulating images.json files. images.json files provide details about images included in composes.

productmd.images.SUPPORTED_IMAGE_TYPES = ['boot', 'cd', 'docker', 'dvd', 'ec2', 'kvm', 'live', 'netinst', 'p2v', 'qcow2', 'raw-xz', 'rescue', 'vagrant-libvirt', 'vagrant-virtualbox']¶: supported image types

productmd.images.SUPPORTED_IMAGE_FORMATS = ['iso', 'qcow', 'qcow2', 'raw', 'raw.xz', 'rhevm.ova', 'sda.raw', 'tar.gz', 'tar.xz', 'vagrant-libvirt.box', 'vagrant-virtualbox.box', 'vdi', 'vmdk', 'vmx', 'vsphere.ova']¶: supported image formats, they match with file suffix

Classes¶

Parameters:	variant (str) – compose variant UID arch (str) – compose architecture image (`Image`) – image

dump(f)¶

Dump data to a file.

Parameters:	f (file or str) – file-like object or path to file

dumps()¶
