Terraform Block
It is used to define global configuration and behavior for terraform execution
- Setting the required Terraform version.
- Configuring the backend for storing the state file.
- Defining experimental or optional features.
- Specifying variables used across multiple modules or configurations.
Example:
terraform { required_version = ">= 0.12" backend "s3"
{ bucket = "terraform-state-bucket" key
= "terraform.tfstate" region = "us-west-2" } }
Different Types of Blocks in Terraform
Terraform is an infrastructure as a code tool that allows you to define and configure your infrastructure using your declarative code. Its syntax is very simple. Terraform uses a configuration language to describe the desired state of your infrastructure, and this language is composed of various block types. These block types play a crucial role in defining and configuring infrastructure in Terraform.
In Terraform, a block is a fundamental unit used to define and configure different aspects of your infrastructure. Blocks are written in HashiCorp Configuration Language (HCL) and allow you to declare resources, providers, variables, outputs, and other configuration elements within your Terraform code.
Each block serves a specific purpose and has its own syntax and set of properties. Here are some common block types used in Terraform:
