This repository provides the build tool to build binary packages in aa safe and reproducible way. It can be used standalone or within theOpen Build Service (OBS).

Latest packages for obs-build are available fromopenSUSE: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 inside of KVM. This canbe considered also secure and reproducible.
• The "emulator" VM can be used to run builds using any otheremulator via a wrapper script.
• A QEMU user land emulation is also possible. This would givehigher speed, but requires a preparation inside of the basedistribution 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

Image formats

• Dockerfile—Docker container via docker or podman tooling)
• kiwi appliances—This includes a long list of formatssupported by the kiwi toolFrom live USB stick images, network deployment images, VM imagesto docker containers

• SimpleImage—chroot tar ball based on rpm spec file syntax
• Debian Livebuild
• Preinstallimages—for speeding up builds esp. inside of OBS
