Terraform Configuration Language Syntax	Learn Terraform Configuration Language Syntax like Blocks, Arguments, Comments etc

Step-01: Introduction

• Understand Terraform Language Basics

1. Understand Blocks
2. Understand Arguments, Attributes & Meta-Arguments
3. Understand Identifiers
4. Understand Comments

Step-02: Terraform Configuration Language Syntax

• Understand Blocks
• Understand Arguments
• Understand Identifiers
• Understand Comments
• Terraform Configuration
• Terraform Configuration Syntax

# Template
<BLOCK TYPE> "<BLOCK LABEL>" "<BLOCK LABEL>"   {
  # Block body
  <IDENTIFIER> = <EXPRESSION> # Argument
}

# Azure Example
# Create a resource group
resource "azurerm_resource_group" "myrg" { # Resource BLOCK
  name = "myrg-1" # Argument
  location = "East US" # Argument 
}
# Create Virtual Network
resource "azurerm_virtual_network" "myvnet" { # Resource BLOCK
  name                = "myvnet-1" # Argument
  address_space       = ["10.0.0.0/16"]
  location            = azurerm_resource_group.myrg.location # Argument with value as expression
  resource_group_name = azurerm_resource_group.myrg.name # Argument with value as expression
}

Step-03: Understand about Arguments, Attributes and Meta-Arguments.

• Arguments can be required or optional
• Attribues format looks like resource_type.resource_name.attribute_name
• Meta-Arguments change a resource type's behavior (Example: count, for_each)
• Additional Reference
• Resource: Azure Resource Group
• Resource: Azure Resource Group Argument Reference
• Resource: Azure Resource Group Attribute Reference
• Resource: Meta-Arguments
