There are two files that still is need to be commited in future this is Vargantfile configuration and Refactory Changes in Chef and Terraform

New VargantFile

Vagrant.configure("2") do |config|
  config.vm.box = "bento/amazonlinux-2"

  # Run the setup_linux.sh script from the packer directory
  config.vm.provision "shell", path: "infra/packer/setup_aws_linux.sh"

  # Provision with Chef Solo
  config.vm.provision "chef_solo" do |chef|
    chef.add_recipe "cloudwatch"
    chef.add_recipe "postgresql"
    chef.add_recipe "ssm"

    # Specify the new path to your cookbooks
    chef.cookbooks_path = ["./infra/cookbooks"]
    
    # Update the roles path if you have any roles
    chef.roles_path = "path/to/roles" # Update this path as needed
  end
end

Refactoring process for future terraform main.tf file, so the variables should be updated too.

# ... existing configuration ...

# Example usage of for_each to create multiple instances
resource "aws_instance" "example" {
  for_each = var.instance_configuration

  ami           = each.value.ami
  instance_type = each.value.instance_type
  key_name      = each.value.key_name
  # ... other configuration ...

  tags = {
    Name = each.value.name
  }
}

Function implementation inside the bashscripts for optimizing the automation of our robotus solution:

# ... existing script ...

main() {
  # Обновление системы
  sudo yum update -y

  # Вызов функций установки
  install_cloudwatch
  install_postgres
  install_aws_ssm

  echo "Установка завершена успешно."
}

# The script will only execute the main function if it's run directly, not when sourced from another script
if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
    main
fi

Create Vagrantfile

# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "bento/amazonlinux-2"
  
  # Provision with the shell script
  config.vm.provision "shell", path: "setup_aws_linux.sh"
  
  # Additional Vagrant configuration as required
end
