This repository provides the `build` tool to build binary packages in a
a safe and reproducible way. It can be used standalone or within the
Open Build Service (OBS).
Latest packages for `obs-build` are available from
[openSUSE:Tools downloads](https://software.opensuse.org/download/package?package=obs-build&project=openSUSE%3ATools).
Supported build environments
============================
Unsecure:
- chroot
- LXC
Secure but with limited reproducibility:
- docker
- nspawn
Secure and with full reproducibility:
- KVM
- XEN
- ZVM (S390)
In addition there is currently experimental support for
- UML
- PVM (PowerPC)
- OpenStack
- Amazon EC2
For hardware emulation there are
- qemu
which runs a QEMU system emulator inside of KVM. This can
be considered also secure and reproducible.
- The "emulator" VM can be used to run builds using any other
emulator via a wrapper script.
- A QEMU user land emulation is also possible. This would give
higher speed, but requires a preparation inside of the base
distribution for this mode.
Supported build formats
=======================
Major distribution package formats
- spec to rpm eg SUSE, Fedora, RedHat, CentOS, Mandriva
- dsc to deb eg Debian, Ubuntu
- PKGBUILD to pkg eg Arch Linux
Image formats
- Dockerfile Docker container via docker or podman tooling)
- kiwi appliances This include a long list of formats supported by the kiwi tool.
From live USB stick images, network deployment images, VM images
to docker containers
https://documentation.suse.com/kiwi/9/html/kiwi/building-types.html
- SUSE Product SUSE product media builds
- SimpleImage chroot tar ball based on rpm spec file syntax
- Debian Livebuild
- Preinstallimages for speeding up builds esp. inside of OBS
Desktop Image formats
- AppImage
- FlatPak
- Snapcraft
Special modes and formats:
- debbuild building debian debs our of rpm spec file
- debbootstrap debian builds using debootstrap as engine
- mock rpm spec file build using mock as engine
- collax debian package variation
- fissile docker images based on BOSH dev releases
- helm helm charts
Use the --help option for more information.
