Book description
Discover how to manage and scale your infrastructure using Infrastructure as Code (IaC) with Terraform
Key Features
- Get up and running with the latest version of Terraform, v0.13
- Design and manage infrastructure that can be shared, tested, modified, provisioned, and deployed
- Work through practical recipes to achieve zero-downtime deployment and scale your infrastructure effectively
Book Description
HashiCorp Configuration Language (HCL) has changed how we define and provision a data center infrastructure with the launch of Terraform—one of the most popular and powerful products for building Infrastructure as Code. This practical guide will show you how to leverage HashiCorp's Terraform tool to manage a complex infrastructure with ease.
Starting with recipes for setting up the environment, this book will gradually guide you in configuring, provisioning, collaborating, and building a multi-environment architecture. Unlike other books, you’ll also be able to explore recipes with real-world examples to provision your Azure infrastructure with Terraform. Once you’ve covered topics such as Azure Template, Azure CLI, Terraform configuration, and Terragrunt, you’ll delve into manual and automated testing with Terraform configurations. The next set of chapters will show you how to manage a balanced and efficient infrastructure and create reusable infrastructure with Terraform modules. Finally, you’ll explore the latest DevOps trends such as continuous integration and continuous delivery (CI/CD) and zero-downtime deployments.
By the end of this book, you’ll have developed the skills you need to get the most value out of Terraform and manage your infrastructure effectively.
