Fedora Arm Secondary Architecture/Koji Builders
To configure a Koji builder system (either VM or physical hardware).
Kojid is the build daemon that runs on each of the build machines. Its primary responsibility is polling for incoming build requests and handling them accordingly. Koji also has support for tasks other than building. Creating install images is one example. kojid is responsible for handling these tasks as well. kojid uses mock for building. It also creates a fresh buildroot for every build. kojid is written in Python and communicates with koji-hub via XML-RPC.

Steps to Perform
Ensure that there is a good amount of space on the ARM system for mock (
/var/cache/mock) before proceeding. You will want a minimum of about 8GB.
On the ARM VMs, you may need to increase the VM size. Stop the VM, add additional storage, and then restart the VM:
On the VM:
Allow 30 seconds for system shutdown.
virsh destroy domain dd if=/dev/zero bs=1M count=8192 >>/var/lib/libvirt/images/arm/domain.img fsck -f /var/lib/libvirt/images/arm/domain.img resize2fs /var/lib/libvirt/images/arm/domain.img virsh start domain
Where domain is the VM name, such as
If using a physical ARM system, ensure that
/var/cache/mock have sufficient space, perhaps by symlinking them to subdirectories of the mountpoint of an external disk, NFS share, or iSCSI block device.
yum install koji-builder
Perform the steps outlined on the NFS Configuration page, including adding entries to the /etc/hosts file.
/etc/kojid/kojid.conf: This needs to point at your koji-hub.
; The URL for the xmlrpc server server=http://hongkong/kojihub ; the username has to be the same as what you used with add-host ; in this example follow as below user = arm-001-001 ;Matches your VM name ; The URL for the packages tree pkgurl=http://hongkong/yum/arm_built/base/12/arm/ ; This item may be changed, but may not be the same as KojiDir on the kojihub.conf file (although it can be something under KojiDir, just not the same as KojiDir) ; The directory root for temporary storage workdir=/tmp/koji
SSL Certificates For Authentication
Copy the appropriate certificate(s) from
;client certificate ; This should reference the builder certificate we created above, for ; kojibuilder1.example.com cert = /etc/kojid/arm-001-008.pem ;certificate of the CA that issued the client certificate ca = /etc/kojid/koji_ca_cert.crt ;certificate of the CA that issued the HTTP server certificate serverca = /etc/kojid/koji_ca_cert.crt
After, start Kojid and configure it to start at each boot:
service kojid start chkconfig kojid on
/var/log/kojid.log on the builder to verify that kojid has started successfully.
Finally, check the Koji hosts web display on HongKong to see that the host is working properly -- it should be enabled, ready, and checking it.
