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)

Experimental support

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. This can be considered also secure and reproducible. It requires a kernel image as part of the build config.
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, e.g. SUSE, Fedora, RedHat, CentOS, Mandriva
dsc to deb, e.g. Debian, Ubuntu
PKGBUILD to pkg, e.g. Arch Linux
