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.

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

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
