Provisioning using Terraform and ansible

Step1: Creating a terraform instance and installing terraform on that .

created bash file to install.

sudo su
apt-get update -y
#Now we will install terraform create the terra_install bash file and run it
vi terra_install.sh

sudo apt-get update && sudo apt-get install -y gnupg software-properties-common
wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
gpg --no-default-keyring \
--keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
--fingerprint
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update -y
sudo apt-get install terraform -y

Step 2. writing Script to install ansible master and playbook running.

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
    }
  }
}

provider "aws" {
  region  = "us-east-1"
  access_key = "YOUR_ACCESS_KEY"
  secret_key = "YOUR_SECRET_KEY"
}

resource "aws_instance" "ansible" {
  ami           = "ami-053b0d53c279acc90"
  instance_type = "t2.micro"
  key_name      = "pratice"
  subnet_id     = "subnet-02f1ba0ff720df4f0"

  tags = {
    Name = "ansible-instance"
  }

  user_data = <<-EOF
    #!/bin/bash
    apt-get update
    apt-get install -y software-properties-common
    apt-add-repository --yes --update ppa:ansible/ansible
    apt-get install -y ansible
  EOF

  connection {
    type        = "ssh"
    user        = "ubuntu"
    private_key = file("pratice.pem")
    host        = self.public_ip
  }

  provisioner "local-exec" {
    command = "/usr/bin/ansible-playbook -i ${self.public_ip}, playbook.yml"
  }
}

Step 3.to apply use the command

terraform apply

Step4. To destroy use the below command

terraform destroy
