Bootstrap i686

Koji, by default, does not build packages as multiarch, it expects a i686 repo/buildroot as that is what mock expects. It appears that it requires a 32 bit bootstrap to start off. However, Enterprise Linux 8 does not have a 32 bit repo. To get around this, packages have to be bootstrapped using at least Fedora 28 (and Fedora 29 for couple of instances).

Setup

Install Mock and Configuration

Install mock...

% yum install epel-release
% yum install mock createrepo_c httpd -y
% useradd rpmbuild
% usermod -aG mock rpmbuild

Add a proper mock configuration...

% cat >> /etc/mock/rocky-8-i686.cfg << "EOF"

# with koji's mock settings

Setup the recursive repo

So we can create an empty repo so mock/dnf is ok with that. However, that won't cut everything. We need a couple RPM's first. We can pull the noarch packages that centos has right now to get us started.

% mkdir -p /var/www/html/src/{reqs,logs,mirror,hidden}

# Pull required RPM's
% wget http://mirror.centos.org/centos/8.3.2011/AppStream/x86_64/os/Packages/redhat-rpm-config-123-1.el8.noarch.rpm

# Generate repo data
% createrepo /var/www/html/src/reqs

Pull required hidden deps

We still need some hidden dependencies. And a lot of these can be built without a problem after the above has been setup. Below is a list, which can be found on our temporary copr. You should download the source RPM's and build them.

You won't find a rocky-logos or rocky-release in copr. However you may find them in our koji. Highly recommended downloading them from koji and building them.

Optional: Pull all the sources from the vault

You may need to pull all the sources from the vault. I used httrack to do this. Note that the link may die and you may need to build it yourself.

Another thing is, after I pulled down the sources, I deleted all the old stuff and moved all the module packages.

% cd /var/www/html/src/mirror
# -sN 0 helps ignore robots
% httrack https://vault.centos.org/8.3.2011/BaseOS/Source/SPackages/ -sN 0
% httrack https://vault.centos.org/8.3.2011/AppStream/Source/SPackages/ -sN 0
% httrack https://vault.centos.org/8.3.2011/HighAvailability/Source/SPackages/ -sN 0
% httrack https://vault.centos.org/8.3.2011/PowerTools/Source/SPackages/ -sN 0

# Now we need to move some things
% mv vault.centos.org/8.3.2011/BaseOS/Source/SPackages/ BaseOS
% mv vault.centos.org/8.3.2011/AppStream/Source/SPackages/ AppStream
% mv vault.centos.org/8.3.2011/HighAvailability/Source/SPackages/ HighAvailability
% mv vault.centos.org/8.3.2011/PowerTools/Source/SPackages/ PowerTools
% rm -rf vault.centos.org index.html

# I don't want to build modules. I'm doing that in koji, so instead, I'm moving them away.
% mkdir modules
% find . -type f -regextype sed -regex '.*module.*\.rpm' -exec mv {} modules/ \;

# Now I need to remove all the old stuff
# You can use repomanage on directories that are not actual repos and it will operate properly.
% for x in AppStream BaseOS HighAvailability PowerTools ; do rm $(repomanage --keep=1 ${x}) ; done

Actually build

I have a kind of hacky script that takes care of this for me. You can feed it one at a time.

# ~/bin/build-a-rpm
#!/bin/bash
PACKAGE=$1
LOGDIR=/var/www/html/src/logs/${NAME//.src.rpm/}
MOCKDIR=/var/lib/mock/rocky-8-i686
mock -r rocky-8-i386 $1

if [ $? -eq 0 ]; then
  rm ${MOCKDIR}/result/*.src.rpm
  cp ${MOCKDIR}/result/*.rpm /var/www/html/src/reqs
  createrepo /var/www/html/src/reqs
  echo $1 >> /tmp/DONE
else
  mkdir ${LOGDIR}
  cp ${MOCKDIR}/result/*.log ${LOGDIR}
  echo $1 >> /tmp/FAIL
fi
% build-a-rpm /var/www/html/src/mirror/BaseOS/tar-1.30-5.el8.src.rpm
