Architecture of Terraform
- Terraform is developed in Go language and installation of terraform is one executable
- Providers are not part of terraform installations as we try to create infra, as part of initializations providers are downloaded
- Providers have resources and datasources as part of it
Concepts of Terraform
- Provider: This determines the target area to create infra structure
- Refer Here for the list of providers
- Terraform providers are of three categories
- official
- partner
- community
- Refer Here for providers documenation by hashicorp
- Note: For you reference we have used the following template
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "2.33.0"
}
azurerm = {
source = "hashicorp/azurerm"
version = "=3.0.0"
}
}
}
provider "azurerm" {
features {
}
}
provider "aws" {
region = "us-west-2"
}
resource "aws_instance" "fromtf" {
ami = "ami-03f65b8614a860c29"
tags = {
Name ="from terraform"
}
key_name = "my_id_rsa"
vpc_security_group_ids = ["sg-05adaf452b268c335"]
instance_type = "t2.micro"
}
resource "azurerm_resource_group" "test" {
name = "test"
location = "eastus"
}
- Arguments and Attributes:
- Argument refers to inputs in terraform
- Attributes refers to outputs in terraform
