While writing and updating training material for our Icinga 2 courseware, we are also re-evaluating the installation and configuration process by practical example and learning curve. Certain parts of the Icinga2 documentation are updated similar to the training material from training participants feedback and also by the trainers themselves.
In this special example, we found it tremendously hard to install the icinga rpm repository from packages.icinga.org inside the CentOS 7 training VM. By default you would just type a long string to fetch the yum repository information.
# wget https://packages.icinga.com -O /etc/yum.repos.d/ICINGA-release.repo # yum makecache
While this works pretty well for release repositories, how about the snapshot repository for testing bleeding edge stuff? Similar to EPEL release package we’d just want that for Icinga as well.
The RPM package called ‚icinga-rpm-release‘ contains the repository’s GPG key as well as the yum configuration for the release repository which is enabled by default. The snapshot repository is installed, but disabled. You may use it with the „–enablerepo“ yum parameter.
Example for el7:
Name: icinga-rpm-release Version: 7 Release: 1%{?dist} Summary: Icinga Package Repository Group: System Environment/Base License: GPLv2 URL: https://packages.icinga.com Source0: %{name}-%{version}.tar.gz Source1: https://packages.icinga.com Source2: https://packages.icinga.com Source3: https://packages.icinga.com BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) BuildArch: noarch Requires: redhat-release >= %{version} %description This package contains the Icinga package repository GPG key as well as configuration for yum. %prep %setup -q -c -T install -pm 644 %{SOURCE0} . %build %install rm -rf $RPM_BUILD_ROOT #GPG key install -Dpm 644 %{SOURCE1} $RPM_BUILD_ROOT%{_sysconfdir}/pki/rpm-gpg/RPM-GPG-KEY-ICINGA #yum install -dm 755 $RPM_BUILD_ROOT%{_sysconfdir}/yum.repos.d install -pm 644 %{SOURCE2} %{SOURCE3} $RPM_BUILD_ROOT%{_sysconfdir}/yum.repos.d %clean rm -rf $RPM_BUILD_ROOT %files %defattr(-,root,root,-) %config(noreplace) /etc/yum.repos.d/* /etc/pki/rpm-gpg/* %changelog
All distribution releases are organized in git branches, which keeps it fairly simply for Jenkins package builds.
Tip: Downloading the url-referenced sources („SourceX: Url“) works using spectool.
$ cd sources $ spectool -g ../icinga-rpm-release.spec modify, add, commit
In the end, you’ll get a nice rpm which installs just fine. No need to worry about the GPG key or where to store the configuration files.
# rpm -i https://packages.icinga.com # yum search icinga2
See you in the icinga2 training sessions!
