Ubuntu Server 18.04 – Automating Server Configuration with Ansible

How to install Ubuntu Server 19.10

Nowadays, it’s not uncommon to have hundreds of servers that make up your organization’s infrastructure. As our user base grows, we’re able to scale our environment to meet the demands of our customers. As we scale our resources and add additional servers, the amount of time we spend configuring them and setting them up increases considerably. The time spent setting up new servers can be a major burden—especially if we need to create hundreds of servers within a small window of time. As workload demands increase, we need to have a solution in place to manage our infrastructure and quickly deploy new resources with as minimal of a workload as possible. In this chapter, we explore the concept of configuration management along with automated deployments. This sure sounds complicated, but it’s not—you’ll be surprised how easy it is to automate your configuration.

In this chapter, we will cover:

  • Understanding the need for configuration management
  • Why Ansible?
  • Creating a Git repository
  • Getting started with Ansible
  • Making your servers do your bidding
  • Putting it all together: Automating a web server deployment
  • Using Ansible’s pull method
