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.

Opstree SHOA Part 1: Build & Release

At Opstree we have started a new initiative called SHOA, Saturday Hands On Activity. Under this program we pick up a concept, tool or technology and do a hands on activity. At the end of the day whatever we do is followed by a blog or series of blog that we have understood during the day.

Since this is the first Hands On Activity so we are starting with Build & Release

 

What we intend to do 

 

Setup Build & Release for project under git repository https://github.com/OpsTree/ContinuousIntegration.

What all we will be doing to achieve it

• Finalize a SCM tool that we are going to use puppet/chef/ansible.
• Automated setup of Jenkins using SCM tool.
• Automated setup of Nexus/Artifactory/Archiva using SCM tool.
• Automated setup of Sonar using SCM tool.
• Dev Environment setup using SCM tool: Since this is a web app project so our Devw443 environment will have Nginx & tomcat.
• QA Environment setup using SCM tool: Since this is a web app project so our QA environment will have Nginx & tomcat.
• Creation of various build jobs
• Code Stability Job.
• Code Quality Job.
• Code Coverage Job.
• Functional Test Job on dev environment.
• Creation of release Job.
• Creation of deployment job to do deployment on Dev & QA environment.

This activity is open for public as well so if you have any suggestion or you want to attend it you are most welcome
