This document discusses using Ansible and Jenkins for continuous integration and continuous delivery (CI/CD). It provides an overview of the tools that will be used in the example lab, including Vagrant, Sonar Source, Maven, GIT, Nexus, Jenkins, and Ansible. It outlines the reference architecture and pipeline flow, and describes how Ansible playbooks will be used to provision lab infrastructure with Vagrant and deploy applications from the Jenkins pipeline. Resources are provided for reproducing the lab, including links to the example application, Ansible plugin, and Vagrant code repository.

INTRODUCTION
What is this all about?
● Jenkins is great for CI/CD implementation.
● Ansible is a great tool for provisioning.
● Why not reuse our Ansible Roles?
● This process could be applied in different scenarios like on premises, cloud, containers,
bare metal and so on.

TOOLS
For this lab, we are going to use:
● Vagrant + libvirt for virtualization
● Sonar Source for source code quality analysis.
● Maven
● GIT
● Nexus for artifactory repository
● Jenkins for CI/CD process flow
● Ansible for lab provisioning and application deployment

INTEGRATION TIPS
Here some tips to avoid headaches:
● The target machines should have a Jenkins user with sudo to perform the needed
tasks.
● Prefer adding a SSH private key on Jenkins credentials and access it at the pipeline.
The target machines must have the public key.
● Install your roles before running the playbook.
● You may limit the provision on a set of hosts using the “-limit” option

ANSIBLE PLAYBOOKS
Let's going to see each playbook in detail:
● Lab infrastructure provisioning with Ansible and Vagrant
● Application provisioning from Jenkins pipeline and Ansible

RESOURCES
Everything you're going to need to reproduce this lab:
● Ansible Plugin
● Vagrant ALM @ GitHub
● Soccer Stats (example app) @ GitHub
● How to start using Ansible if I no nothing about platform?
