This is a higher level app on top of the core rpm-ostree tool. It
contains a variety of tools and scripts for making disk images,
installer images, and ostree trees.
The rpm-ostree-toolbox should be called with one of three subcommands:
- treecompose
- installer
- imagefactory
Depending on the subcommand being called with rpm-ostree-toolbox, a number of different input files are required. The main configuration file is generally called config.ini. These are intended to be kept inside revision control. For example, this git repository holds the Fedora Atomic configuration:
https://git.fedorahosted.org/cgit/fedora-atomic.git
This allows you to create a tree of ostree content. It takes various inputs from a JSON file to perform most of its actions. When complete, you will have an ostree with content suitable for creating disk images.
Example invocation:
rpm-ostree-toolbox treecompose -c fedora-atomic/config.ini
It will write output into the current working directory.
This command creates ISO and PXE images that can be used as install media. This can either be done with a container-based approach or using libvirt.
With imagefactory, you can create various virtualized images with libvirt related tooling. Currently it is capable of making qcow2, raw, vsphere, and rhevm images. This can be altered with the -i argument.
These need to reference an installer image.
