Spis treści

1 Introduction to HCL

Define the history of HCL, the basic syntax and, show the basic configuration syntax and the basic usage of the HCL

2 The Hashicorp ecosystem

Show the different software create by Hashicorpt like Vault, Consul, Terraform

3 Introduction to Go

A small introduction on the Go language, we use Go to define the configuration template described in the book

4 Infrastructure As Code

Define what is the Infrastructure as Code and how we can do that

5 Introduction to the Cloud and DevOps

In this chapter, we have a short introduction to the Cloud and the DevOps

6 Use HCL for Terraform

We start to use the HCL for define Terraform template

7 Consul HCL

In this chapter we introduce the HCL for Consul, we learn how to configure Consul using the HCL

8 Vault HCL

Use the HCL for configure Vault

9 Infrastructure as Code with HCL

Design the Infrastructure as Code use the Hashicorp language, in particular, we use Terraform, Vault and Consul

10 Provisioning and Maintain the Infrastructure as Code

In this chapter, we see how to use Jenkins and the HCL for provisioning and maintain the infrastructure as code

Get started with programming and using the Hashicorp Language (HCL). This book introduces you to the HCL syntax and its ecosystem then it shows you how to integrate it as part of an overall DevOps approach.

Next, you’ll learn how to implement infrastructure as code, specifically, using the Terraform template, a set of cloud infrastructure automation tools. As part of this discussion, you’ll cover Consul, a service mesh solution providing a full-featured control plane with service discovery, configuration, and segmentation functionality. You’ll integrate these with Vault to build HCL-based infrastructure as code solutions.  

Finally, you’ll use Jenkins and HCL to provision and maintain the infrastructure as code system. After reading and using Beginning HCL Programming, you'll have the know-how and source code to get started with flexible HCL for all your cloud and DevOps needs.  

You will:

• Get started with programming and using HCL
• Use Vault, Consul, and Terraform
• Apply HCL to infrastructure as code
• Define the Terraform template with HCL
• Configure Consul using HCL
• Use HCL to configure Vault
• Provision and maintain infrastructure as code using Jenkins and HCL
