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

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.
