Installing Jenkins using Ansible Playbook on Ubuntu

-

Find below Ansible playbook for installing Jenkins on a Ubuntu machine.


Pre-requisites:
Java needs to be installed already on machine before setting up Jenkins. Here below is the playbook for installing Jenkins using Ansible in Ubuntu EC2:

sudo vi installJenkins.yml
Copy the below yellow highlighted in the above file: 

---
 - hosts: My_Group
  
   tasks:
    - name: ensure the jenkins apt repository key is installed
      apt_key: url=https://pkg.jenkins.io/debian/jenkins.io-2023.key state=present
      become: yes

    - name: ensure the repository is configured
      apt_repository: repo='deb https://pkg.jenkins.io/debian-stable binary/' state=present
      become: yes

    - name: ensure jenkins is installed
      apt: name=jenkins update_cache=yes
      become: yes

    - name: ensure jenkins is running
      service: name=jenkins state=started











sudo vi /etc/ansible/hosts
make sure you add below entry with target node IP changed (in red color).
[My_Group]  
xx.xx.xx.xx ansible_ssh_user=ubuntu ansible_ssh_private_key_file=~/.ssh/id_rsa  ansible_python_interpreter=/usr/bin/python3




Execute the below command:
ansible-playbook installJenkins.yml

This should install Jenkins on the target node and should install Jenkins.

Now enter public ip address or public dns name with port no 8080 of target server by in the browser to see Jenkins up and running.

http://target_node_public_dns_name:8080

Setup build agent/slave VM and Integrate with Jenkins Master

Jenkins has powerful feature of master slave architecture which enables distributed builds. This article we will learn how to establish slave nodes on Ubuntu machines and integrate with Jenkins Master. Jenkins Master Your main Jenkins server is the Master. The Master’s job is to handle: Scheduling build jobs. Dispatching builds to the slaves for the actual execution. Monitor the slaves (possibly taking them online and offline as required). Recording and presenting the build results. A Master instance of Jenkins can also execute build jobs directly. Jenkins Slave A Slave is a Java executable that runs on a remote machine. Following are the characteristics of Jenkins Slaves: It hears requests from the Jenkins Master instance. Slaves can run on a variety of operating systems. The job of a Slave is to do as they are told to, which involves executing build jobs dispatched by the Master. You can configure a project to always run on a particular Slave machine, or a particular type of Slave ma...

  How to setup SonarQube using Docker compose? SonarQube is static code analyis tool. It is open source and Java based tool. SonarQube can be setup using Docker Compose with less manual steps. What is Docker Compose? Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.  Since Docker Compose lets you configure related containers in a single YAML file, you get the same Infrastructure-as-Code abilities as Kubernetes. But they come in a simpler system that’s more suited to smaller applications that don’t need Kubernetes’ resiliency and scaling.   The purpose of  docker - compose  is to function as  docker  cli but to  issue multiple commands much more quickly. To make use of  docker - compose , you  need  to encode the commands you were running...

What is Amazon EKS Amazon EKS is a fully managed container orchestration service. EKS allows you to quickly deploy a production ready Kubernetes cluster in AWS, deploy and manage containerized applications more easily with a fully managed Kubernetes service. EKS takes care of master node/control plane. We need to create worker nodes. EKS cluster can be created in following ways: 1. AWS console 2. AWS CLI 3. eksctl command 4. using Terraform We will create EKS cluster using eksctl command line tool. Pre-requisites: This Lab is using Jenkins EC2 instance. Jenkins EC2 instance needs to have following configured: Install AWS CLI   – Command line tools for working with AWS services, including Amazon EKS. Install eksctl   –  A command line tool for working with EKS clusters that automates many individual tasks. Install kubectl    – A command line tool for working with Kubernetes clusters.  Create IAM Role with Administrator Access You need to create an IAM r...
