Setup Jenkins using Ansible

In this document I’ll walk you through how you can  setup jenkins using ansible.

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.
Note :  You should have password less login enabled in second machine. use this link

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.
