Introduction

This document describes the steps to create Peer Jenkins server and establish the connection with the LF master Jenkins

Infrastructure Requirements for VM

Minimum hardware requirements:

  • 256 MB of RAM
  • 1 GB of drive space (although 10 GB is a recommended minimum if running Jenkins as a docker container)
  • Ubuntu 16.04 or higher OS

Recommended hardware configuration:

  • 1 GB+ of RAM
  • 50 GB+ of drive space

Software requirements:

  • Java
  • Web browser compatibility
  • Docker to be installed if Jenkins server running as a container


Installation Guide

Install Java

Since Jenkins is a Java application, the first step is to install Java. Update the package index and install the Java 8 OpenJDK package with the following commands

sudo apt-get update
sudo apt install openjdk-8-jdk


Install Docker

Step 1: First, in order to ensure the downloads are valid, add the GPG key for the official Docker repository to your system

curl -s https://apt.dockerproject.org/gpg | sudo apt-key add
apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

Step 2: Add the Docker repository to APT sources

sudo
add-apt-repository "deb https://apt.dockerproject.org/repo ubuntu-$(lsb_release -cs) main"

Step 3: Next, update the package database with the Docker packages from the newly added repo

sudo apt-get update

Step 4 : Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 (xenial):

sudo apt-cache policy docker-engine

You should see output like the follow:

Output of apt-cache policy docker-engine

docker-engine

Step 5: Finally, Install Docker

sudo apt-get install docker-engine=1.13.0-0~ubuntu-xenial

Step 6: Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it's running

sudo systemctl status docker


Setting up the Peer Jenkins server

Step 1 : Pulling the latest jenkins image from docker hub

sudo docker pull jenkins
sudo docker images

Step 2 : create a jenkins.sh file under /data directory

sudo vi jenkins.sh

add below startup script in Jenkins.sh file for running the Jenkins in a container

#!/bin/bash
export DROOT=/data
export DOMAIN=your.domain.name
docker run --detach --name jenkins --restart=always --hostname jenkins.$DOMAIN --volume $DROOT/jenkins:/var/jenkins_home  --volume /var/run/docker.sock:/var/run/docker.sock --publish 80:8080 jenkins/jenkins

save the changes and run the script using below command

./jenkins.sh (or) 
sudo sh jenkins.sh


Step 3 : Pulling the latest jenkins image from docker hub

sudo docker ps
