Introduction

In the ever-evolving world of modern computing, the demand for efficient and scalable infrastructure management has never been greater. Traditional manual approaches to infrastructure provisioning and configuration are no longer sufficient to meet the demands of today's fast-paced businesses. This is where HashiCorp tools come into play. HashiCorp is a leading provider of infrastructure automation and management tools, including Terraform, Vault, Packer, Nomad, and Consul. These tools enable developers and architects to automate the provisioning, configuration, and management of their infrastructure, reducing the time and effort required to deploy and maintain applications.

What You Will Learn

This book is designed to provide a comprehensive guide to getting started with HashiCorp tools. It will cover the methodologies and best practices for using Terraform, Vault, Packer, Nomad, and Consul to automate your infrastructure.

Chapter 1: Introduction to Infrastructure-as-Code

In this chapter, we will introduce the concept of infrastructure-as-code. We will discuss the need for automation and management technologies in modern computing and how HashiCorp tools can help meet these needs. We will also explore the architecture of Terraform, Vault, Packer, Nomad, and Consul and how they work together to automate infrastructure management.

Chapter 2: Hands-On Deployment with Terraform

In this chapter, we will dive into the hands-on deployment of Terraform. We will start by setting up a Terraform environment and creating a simple infrastructure configuration. We will then apply the configuration to a virtual machine using the Terraform apply command. We will also explore the Terraform variables, resources, and modules and how they can be used to create complex infrastructure configurations.

Chapter 3: Configuration and Best Practices with Terraform

In this chapter, we will explore the configuration and best practices for Terraform. We will discuss the importance of version control, testing, and documentation in Terraform configurations. We will also cover advanced topics such as using Terraform with cloud providers such as AWS, Azure, and GCP and leveraging Terraform to manage multi-tenancy and security.

Chapter 4: Hands-On Deployment with Packer

In this chapter, we will dive into the hands-on deployment of Packer. We will start by creating a Packer template that defines the infrastructure configuration for a virtual machine. We will then use the Packer build command to generate a virtual machine image based on the template. We will also explore the Packer variables, resources, and drivers and how they can be used to customize the virtual machine image.

Chapter 5: Image Management with Packer

In this chapter, we will explore the image management with Packer. We will discuss the importance of image consistency and security in modern computing. We will also cover advanced topics such as using Packer to create multi-architecture virtual machine images and leveraging Packer to automate the deployment of containerized applications.

Chapter 6: Application Orchestration with Nomad and Consul

In this chapter, we will explore the application orchestration with Nomad and Consul. We will discuss the benefits of using a decentralized and distributed infrastructure management approach. We will also cover the installation and configuration of Nomad and Consul and how they can be used to manage application deployment and service discovery.

Chapter 7: Automated Infrastructure and Application Deployment on the VM/Container Base Ecosystem

In this chapter, we will explore the automated infrastructure and application deployment on the VM/container base ecosystem. We will discuss the benefits of using virtualization and containerization for infrastructure management. We will also cover the installation and configuration of popular virtualization and containerization platforms such as VMware, Hyper-V, and Docker.

Conclusion

In conclusion, this book provides a comprehensive guide to getting started with HashiCorp tools. It covers the methodologies and best practices for using Terraform, Vault, Packer, Nomad, and Consul to automate your infrastructure. By following the steps outlined in this book, you will be able to reduce the time and effort required to deploy and maintain applications, while also improving the scalability and reliability of your infrastructure.
