{{Note box|This howto is for building your own koji build farm.

For how to use the koozali.org build farm, please see [[Koji Usage]]}}

Official Koji documentation can be found at: https://docs.pagure.org/koji/

And some components do not work yet}}

And some components do not work yet.}}

I'll document what I have done so far, what is working and what is not.

Line 13: Line 16:

Major Koji components:

−

* hub

* hub (koji-hub)

−

* web server

* web server (koji-web)

−

* ~~build servers~~

* builders

−

* build daemon

* build daemon (kojid)

−

* Dnf|Yum repository creation and maintenance daemon

* Dnf|Yum repository creation and maintenance daemon (kojira)

You need at least the one server which can perform all functions, or split it into a hub, web plus 1+ build servers.

A typical scenario will be to have 2+ servers.

* hub - which will run the hub, web and dnf|Yum repository daemon

* builders - there can be multiple of these

For our purposes, all of these servers will be based on bare Rocky 8 - minimal install, servers.

== Install ==

{{Note box|1=You can run everything (the hub, web and build) on the one server, just run the script without any parameters.}}

Create your hub, web and build servers (Rocky 8 minimal install).

On all servers enable the network and name the servers as the FQDN (the servers need to be accessible via their FQDN's, so either via DNS or you need to add them to your /etc/hosts files).

It's also a good idea to update them to the latest

nmtui

dnf update

</syntaxhighlight>

Log into the hub server, download and run the install script

curl https://src.koozali.org/smedev/smeserver-koji/raw/branch/master/install-koji-farm.sh > install-koji-farm.sh

chmod o+x install-koji-farm.sh

./install-koji-farm.sh

</syntaxhighlight>

The install-koji-farm.sh script will accept multiple parameters<syntaxhighlight lang="bash">

install-koji-farm.sh [web=<web FQDN> | build=<build FQDN> | scm=<scm ip or name>:/* | debug]

</syntaxhighlight>

* web=<FQDN> - defaults to hub FQDN

*build=<FQDN> - multiple allowed

*scm=<IP or Name of SCM>:/* - multiple allowed

*debug - will list each line executed, plus lots of other gunk (very noisy)

You will be prompted for various items

*values for your ssl certificates (e.g. Country, State, City, Organization, Organisational Unit)

* For the web server (unless it's the hub)

**to accept the build server signature

**for the root password on the web server

*For each build server

**to accept the build server signature

**for the root password on the build server

The web interface will be available via http://<your hub server>/koji

=== Build Targets ===

This will have created 6 build targets with various build tags to use

* dist-sme10-os (dist-sme10-os-build)

* dist-sme10-contribs (dist-sme10-contribs-build)

* dist-sme11-os (dist-sme11-os-build)

* dist-sme11-contribs (dist-sme11-contribs-build)

* dist-sme12-os (dist-sme12-os-build)

* dist-sme12-contribs (dist-sme12-contribs-build)

There is a hierarchy inheritance structure for each release (see 10, 11 & 12), where the basic settings are inherited (e.g. yum or dnf, centos:7 or rockylinux:8 bootstrap image for mock) as well as which external repositories to use (e.g. centos7/el7 versions or rocky8/el8 versions)

+ dist-sme<release>-os

++ dist-sme<release>-os-build

++ dist-sme<release>-contribs

+++ dist-sme<release>-contribs-buikl

++ dist-sme<release>-addons

−

~~In our build, we will have only 2 servers.~~

++ dist-sme<release>-testing

−

* hub - ~~which will run the hub, web, build daemon and def|Yum repository daemon~~

++ dist-sme<release>-updates

−

* build server - ~~there can be multiple of these, but we'll just do 1 to start with~~

−

~~These servers will be based on bare Rocky 8~~ - ~~minimal install, servers.~~

===== Hub/Web Server =====

How to build etc. will be covered in the 'to be written' koji usage page......

===Additional Builders===

You can add additional build servers later, via<syntaxhighlight lang="bash">

koji-add-builder.sh <FQDN of build server> [debug]

</syntaxhighlight>

===Additional Users===

You can add end Users via

koji-add-user.sh <User Name> [ permission=<permission> | debug ]

</syntaxhighlight>

Where <permission> could be "admin".

This will add the user into the koji db and generate ssl CLI and browser keys, which will be bundled up in a tgz file at /etc/pki/koji/bundle/koji-<User Name>-bundle.tgz.

This bundle should be copied and extracted into their home (~) directory and will create a .koji directory containing config and keys.This can be on a remote machine with the koji client installed.

cd ~

tar -zxf koji-<User Name>-bundle.tgz

koji moshimoshi

</syntaxhighlight>

=== Bootstrap ===

The setup of the repos used for building SME10, SME11 & SME12 are all included in the install script, but a brief description of what has been setup seems sensible.

==Install - The long way (Beware: Demons lurk here) ==

{{Warning box|This has been left here to help understand what is in the scripts (which may have changed since this was written)}}

====Koji Builders====

For this exercise I only created 1 build server. You can have as many as you like...

OS: Rocky 8.8-minimal

Memory: 8GB

Disk: 20GB (can apparently use a lot of disk, depending on how active a build server it is)

FQDN: build1.koozali.org

=====Koji Hub setup for build server=====

First off, set up some items on the koji hub for your build server/s

Create a ssl cert for the build server with CN=build1.koozali.org<syntaxhighlight lang="bash">

koji_make_cert.sh build1.koozali.org

</syntaxhighlight>

Add the build server into the koji database<syntaxhighlight lang="bash">

su - kojiadmin

koji add-host build1.koozali.org x86_64 noarch

koji add-host-to-channel build1.koozali.org createrepo

exit

</syntaxhighlight>

We'll want the build servers to have access to the koji filesystem via nfs, so on the koji hub server (koji.koozali.org)<syntaxhighlight lang="bash">

dnf install nfs-utils

systemctl enable --now nfs-server

systemctl start nfs-server

nano /etc/exports

</syntaxhighlight>we only have one build server, but you can add additional build servers to the line, separated by a space<syntaxhighlight lang="ini">

firewall-cmd --permanent --add-service=nfs

firewall-cmd --permanent --add-service=mountd

firewall-cmd --permanent --add-service=rpc-bind

firewall-cmd --reload

</syntaxhighlight>

=====Builder setup=====

You'll need to set up your network: You can do this during the install or post install (ensure network activated, IP address, FQDN, Gateway, DNS)

Log into your build server as root and<syntaxhighlight lang="bash">
