README for kamailio-deb-jenkins

This repository provides configuration and scripts as used by the server for building Debian packages for the Kamailio project.

Development of this setup is sponsored by Sipwise.

Involved Software

• Debian (amd64)
• Jenkins
• jenkins-debian-glue
• Jenkins Job Builder

Deployment instructions

NOTE: Using user admin for administration as present on EC2, adjust if necessary.

Install etckeeper for tracking changes in /etc:

sudo apt-get -y install etckeeper git

Automatically deploy jenkins-debian-glue:

wget https://raw.github.com/mika/jenkins-debian-glue/master/puppet/apply.sh
sudo bash ./apply.sh $PASSWORD

Use custom systemd unit for jenkins service:

sudo systemctl stop jenkins
sudo ln -s /home/admin/kamailio-deb-jenkins/jenkins/jenkins.service /etc/systemd/system/jenkins.service
sudo systemctl daemon-reload
sudo systemctl restart jenkins

Support providing additional configuration to cowbuilder + related tools:

sudo tee -a /etc/sudoers.d/jenkins >/dev/null <<EOF
# for *-binaries job
jenkins ALL=NOPASSWD: /usr/sbin/cowbuilder, /usr/sbin/chroot
# for *-piuparts job
jenkins ALL=NOPASSWD: /usr/sbin/piuparts, /usr/sbin/debootstrap, /usr/bin/piuparts_wrapper

# for cowbuilder instruction:
Defaults  env_keep+="architecture branch distribution release ARCH DEB_* DIST JOB_NAME MIRROR PIUPARTS_* LINTIAN*"
EOF

Grab a copy of this repository:

git clone https://github.com/sipwise/kamailio-deb-jenkins.git /home/admin/kamailio-deb-jenkins

Adopt pbuilder for usage with building for Ubuntu:

echo PBUILDER_CONFIG=/etc/jenkins/pbuilderrc | sudo tee -a /etc/jenkins/debian_glue
sudo cp /home/admin/kamailio-deb-jenkins/pbuilder/pbuilderrc /etc/jenkins/pbuilderrc
sudo dpkg -i /home/admin/kamailio-deb-jenkins/debs/ubuntu-keyring_2012.05.19_all.deb

Deploy nginx as proxy for Jenkins (consider adjusting this using Let's Encrypt SSL certificates though!):

sudo apt-get -y install nginx
sudo openssl req -days 3650 -nodes -new -x509 -keyout /etc/ssl/private/server.key -out /etc/ssl/private/server.cert
sudo cp /home/admin/kamailio-deb-jenkins/nginx/default /etc/nginx/sites-available/default
sudo /etc/init.d/nginx restart

Set up Debian repository directories:

sudo mkdir -p /srv/repository
sudo chown jenkins /srv/repository
sudo ln -s /srv/repository/ /srv/debian

GPG key setup for Debian repository:

sudo apt-get install haveged
sudo -s
su - jenkins
gpg --gen-key # note $KEY_ID
gpg --armor --export $KEY_ID --output /srv/debian/kamailiodebkey.gpg
echo KEY_ID=$KEY_ID | sudo tee -a /etc/jenkins/debian_glue

Set up jenkins-job-builder:

sudo mkdir -p /etc/jenkins_jobs
sudo tee -a /etc/jenkins_jobs/jenkins_jobs.ini >/dev/null <<EOF
[jenkins]
user=jenkins-job-builder
password=$PASSWORD
url=http://localhost:8080/
EOF

Install Matrix Reloaded Jenkins Plugin:

sudo wget -O /var/lib/jenkins/plugins/matrix-reloaded.hpi http://updates.jenkins-ci.org/latest/matrix-reloaded.hpi
sudo chown jenkins:nogroup /var/lib/jenkins/plugins/matrix-reloaded.hpi

Install Build Blocker Jenkins Plugin:

sudo wget -O /var/lib/jenkins/plugins/build-blocker-plugin.hpi http://updates.jenkins-ci.org/latest/build-blocker-plugin.hpi
sudo chown jenkins:nogroup /var/lib/jenkins/plugins/build-blocker-plugin.hpi

Install Build-timeout Plugin:

sudo wget -O /var/lib/jenkins/plugins/build-timeout.hpi http://updates.jenkins-ci.org/latest/build-timeout.hpi
sudo chown jenkins:nogroup /var/lib/jenkins/plugins/build-timeout.hpi

Install groovy-label-assignment Plugin:

sudo wget -O /var/lib/jenkins/plugins/groovy-label-assignment.hpi http://updates.jenkins-ci.org/latest/groovy-label-assignment.hpi
sudo chown jenkins:nogroup /var/lib/jenkins/plugins/groovy-label-assignment.hpi

Adjust for usage with headless Java (if not already present):

echo JAVA_ARGS="-Djava.awt.headless=true" | sudo tee -a /etc/default/jenkins

Generate according Jenkins jobs:

cd /home/admin/kamailio-deb-jenkins/jjb
make

Build slave setup

It's possible to run the build process on a separate Jenkins slave. To set up the build slave follow those steps:

sudo apt update
sudo apt -y install git gnupg
git clone https://github.com/sipwise/kamailio-deb-jenkins
cd kamailio-deb-jenkins/
./ec2/bootstrap.sh -l  # list supported distributions
sudo ./ec2/bootstrap.sh -u $DISTRIBUTION  # e.g. bullseye

Depending on your setup, connect the slave to your master then (SSH, swarm plugin, Amazon EC2 plugin,...).
