openSUSE:Build Service Appliance
It's best to prepare the hosts you deploy the OBS appliances to with a LVM volume group of the name "OBS". This volume group should be as big as possible because it get's used by the OBS server components for data storage and the OBS workers for root/swap/cache file systems.
vgcreate "OBS" /dev/sdX1
The OBS server images contain a recent openSUSE distribution with a pre-installed and pre-configured OBS backend, API, web frontend and worker.
The system adapts to the hardware on first boot and defaults to automatic IP and DNS configuration via DHCP. The image scans for a LVM volume group called "OBS" and will use that to set up logical volumes for the workers root/swap/cache file systems. Additionally if this volume group contains a logical volume named "server" it will be used as the data partition for the server.
There are installation images. When you boot, they run a basic installer that lets you choose the block device to deploy the image to.
You put this image on a USB stick and boot from it.
For VirtualBox and VMware there are a configuration file (.vmx) and a disk image (.vmdk). You can load the configuration into VMware workstation/player or VirtualBox.
For QEMU/KVM there is a disk image in the qcow format which you can start.
Raw Disk Image
If you want to deploy directly to a block device there is an file system image (.raw)
There is also an image which includes a recent openSUSE distribtion and only the OBS worker component. The system on this image adapts to the hardware on first boot, defaults to automatic IP and DNS configuration via DHCP and OBS server discovery via SLP. This image is also looking for a LVM volume group with the name "OBS" during boot to create logical volumes for the workers root/swap/cache filesystems.
Raw Disk Image
You can use this file system image to deploy it directly to a block device or boot it with KVM/QEMU.
All images come pre-configured with the right set of repositories and can updated via the system tools YaST or zypper at any time. Another way is to replace the entire image. If you update the image keep in mind that you need to have have your data directory (/srv/obs) on a separate storage (LVM volume, partition etc.) otherwise it will get deleted.
