Study Notes
Introduction to Terraform
- Terraform is an Infrastructure as Code (IaC) tool for automating infrastructure provisioning and management across various cloud providers.
- It supports multiple cloud platforms (AWS, Azure, GCP, on-prem).
- Terraform employs a declarative syntax to define desired infrastructure, not the steps to create it.
- It tracks infrastructure changes using a state file.
- Execution plans show changes before application.
- Terraform works with various cloud environments and custom APIs.
- Advantages include efficient management and consistent infrastructure, while complex projects can present a learning curve.
Installation and Setup
- Terraform installs on Windows, macOS, and Linux.
- Package managers (Homebrew, Chocolatey) help with installation.
- Download the appropriate binary from HashiCorp.
- Place correctly placed the binary in a directory included your system's PATH.
- Verify installation with
terraform -v
. - Initialization from package managers: brew install terraform (macOS) or choco install terraform (Windows).
- A directory (e.g.,
terraform-project
) is created. - Provider configuration (e.g., AWS region) is added to the
.tf
file. terraform init
downloads needed provider plugins.terraform validate
ensures correct configuration syntax.- Cloud platform integration requires specific actions:
- AWS: Configure IAM user and credentials with
aws configure
. - Azure: Authenticate using Azure CLI (
az login
). - GCP: Use gcloud CLI to authenticate (
gcloud auth application-default login
).
- AWS: Configure IAM user and credentials with
- Specify providers (aws, azurerm, google) in
.tf
files with region and other settings.
Terraform Configuration Language (HCL)
- Terraform uses HashiCorp Configuration Language (HCL).
- Configuration is in
.tf
files. - Key elements include providers, resources, variables and outputs.
- Provider Block: Specifies the cloud provider (e.g.,
provider "aws"
). - Resource Block: Defines infrastructure elements (e.g., EC2 instances). The syntax is
resource "resource_type" "resource_name" { key = "value" }
. - Data Source Block: Fetches data from existing infrastructure (e.g.,
data "aws_ami"
). - Variable Block: Allows configurable inputs (e.g., region). The syntax is
variable “variable_name” { type = string, default = "default_value", description = "…"}
- Output Block: Shows values after execution. The syntax is
output "output_name" { value = … }
