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:

...

• 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

...

sudo systemctl status docker

Setting up the Peer Jenkins server

Step 1 : Pulling the latest jenkins image from docker hub

...

• if the Jenkins container is restarting again and again then check the logs using below command

  Code Block
  language bash
  sudo docker logs --tail 50 –follow --timestamps Jenkins

  
  

• If the logs are showing like below Wrong volume permissions?
  

  Code Block
  language bash
  touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied Can not write to /var/jenkins_home/copy_reference_file.log.

  The volume directory /data/jenkins need to be separated with the admin ownership to keep the Jenkins home

  Code Block
  language bash
  sudo chown 1000 /data/Jenkins

  Then run the command: (Now the container is up and running)

  Code Block
  language bash
  sudo docker ps -a

  Executing into Jenkins container

  Code Block
  language bash
  sudo docker exec -it jenkins /bin/bash

  Inside the Jenkins container, go to /var/Jenkins_home/secrets/ directory. Copy the initial admin password like this

  Code Block
  language bash
  cat /var/Jenkins_home/secrets/initialAdminPassword

  
  

Accessing Jenkins Peer and continue setup

Default port for Jenkins is 8080 and this should be open. To set up your new Jenkins installation, open your browser and type your domain or IP address followed by port 8080

...

Finally, click on the Start using Jenkins button and you will be redirected to the Jenkins dashboard logged in as the admin user you have created in one of the previous steps.

If you’ve reached this point, you’ve successfully installed Jenkins.
