Fedora Arm Secondary Architecture/Koji Builders

Revision as of 15:56, 15 April 2010 by Dpcabra1 (talk | contribs) (→‎Add the host entry for the koji builder to the database)

Koji Daemon - Builder

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.

Configuration Files:

  • /etc/kojid/kojid.conf - Koji Daemon Configuration
  • /etc/sysconfig/kojid - Koji Daemon Switches

Install kojid: 

root@localhost$ yum install koji-builder

Required Configuration

/etc/kojid/kojid.conf: This needs to point at your koji-hub. 

; The URL for the xmlrpc server
server=http://hongkong.proximity.on.ca/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

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

/etc/kojid/kojid.conf: If using SSL, these settings need to be valid. 

;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


Add the host to the createrepo channel

Channels are a way to control which builders process which tasks. By default hosts are added to the default channel. At least some build hosts also needs to be added to the createrepo channel so there will be someone to process repo creation tasks initiated by kojira. 

kojiadmin@localhost$ koji add-host-to-channel kojibuilder1.example.com createrepo


Start Kojid

root@localhost$ /sbin/service kojid start

Check /var/log/kojid.log to verify that kojid has started successfully.
