The article provides a comprehensive guide to managing infrastructure using Terraform, an open-source Infrastructure as Code (IaC) tool designed to automate and version control infrastructure configurations. It explains the installation process of Terraform across various operating systems, the HashiCorp Configuration Language (HCL) used for defining infrastructure states, and the significance of Terraform Providers, Resources, Data Sources, and Modules. The guide outlines the Terraform workflow, which involves the commands terraform init, terraform plan, and terraform apply, detailing their roles in initializing configurations, previewing changes, and applying updates to infrastructure. Emphasizing the importance of managing Terraform's state files to track and optimize infrastructure changes, it also touches on advanced topics like importing existing infrastructure. The article concludes by suggesting Earthly as a tool to enhance build automation, while attributing the content to Damaso Sanoja, an experienced writer in the engineering sectors.
