Building RPMs with Mock

I'll try to write down what I need to do to set-up a simple rpm build system using mock, whereby some packages have dependencies on my own builds. The build system I'm using is CentOS 7.

Requirements for the build system

yum install mock createrepo yum-utils

Create the following directories to allow inspection and modification of RPM packages

mkdir -p ~/rpm/BUILD ~/rpm/RPMS ~/rpm/SOURCES ~/rpm/SPECS ~/rpm/SRPMS

Create a ~/.rpmmacros file with the following content

%HOME       %{expand:%%(cd; pwd)}
%_topdir    %{HOME}/rpm

Any source rpm you now install (as regular user) will end up under $HOME/rpm/*

Generate a GPG signing key:

gpg --gen-key

follow the instructions

gpg --export -a 'Jorrit Jorritsma' > ~/RPM-GPG-KEY-jorrit

Import your public key to your RPM DB

sudo rpm --import RPM-GPG-KEY-jorrit

Add the following to your ~/.rpmmacros file

%_signature gpg
%_gpg_path ~/.gnupg
%_gpg_name Jorrit Jorritsma
%_gpgbin /usr/bin/gpg

Singing of packages can now be done with:

rpm --addsign *.rpm

Create a rpm repository under your web server:

sudo mkdir -p /var/www/html/repos
sudo chown jorrit. /var/www/html/repos
mkdir /var/www/html/repos/x86_64
createrepo /var/www/html/repo/x86_64

Add your own repo to your mock config for the target build (e.g. /etc/mock/epel-7-x86_64.cfg)

[jj]
name=jj
baseurl=http://centos7.fritz.box/repo/x86_64/
gpgcheck=0
skip_if_unavailable=False

get the src rpms

mkdir ~/asterisk
cd asterisk
wget -r --no-parent -A *.src.rpm https://ast.tucny.com/repo/

Build the packages

move to the package download location

cd asterisk/ast.tucny.com/repo/asterisk-common/el7/SRPMS

Build
