Prerequisites

•  OS - Ubuntu {at least two machine required in production}
•  First machine for Ansible  installation
•  Second machine where we will install jenkins server
• You should have basic understanding of ansible workflow.

Ansible Installation
Before starting with installing jenkins using ansible, you need to have ansible installed in your system.

 $ curl https://raw.githubusercontent.com/OpsTree/AnsiblePOC/alok/scripts/Setup/setup_ansible.sh | sudo bash

Setup jenkins using Ansible

Install jenkins ansible roles

Once we have ansible installed in our system, we can start installing the jenkins using ansible. To install we will use an already available ansible role to setup jenkins

$ ansible-galaxy install geerlingguy.jenkins

to know more about the jenkins role hit this link https://galaxy.ansible.com/detail#/role/440

Ansible roles default directory path is /etc/ansible/roles
Make ansible playbook file
 

Now the next step is to use the installed jenkins roles to install the jenkins. For this purpose we will create a playbook  and hosts file with below content

$ cd ~/MyPlaybook/jenkins

create a file hosts and add below content

[jenkins_hosts]

192.168.33.15

Next create  a file site.yml and add below content

---

- hosts: jenkins_hosts

 roles:

     - { role: geerlingguy.jenkins }

so configuration file is done, the next step is to run ansible playbook command

$ ansible-playbook -i hosts site.yml

Now that Jenkins is running, go to http://192.168.33.15:8080. You'll be welcome by the default Jenkins screen.
