This is the first part of a series of Demo’s taking you through how to create a basic CICD workflow using Gitlab, Jenkins and Ansible. It’s a real-time demo so please fast forward through any slow bits!

In this demo, I’ll cover the following tasks:

• Start with a newly built Ubuntu 20.04 server
• Install pre-requisite packages
• Install Jenkins
• Install some other helpful packages like ansible, wget, git, etc
• Install the default plugins
• Login and setup the Admin user

All the commands used in the demo are below:
