Create a snippet of Terraform HCL code that create an AWS autoscaling group, and an ALB in front to expose an application to internet.
Sure, here's an example Terraform HCL code that creates an AWS Autoscaling Group and an Application Load Balancer to expose an application to the internet:
``` 
# Configure the AWS provider
provider "aws" {
  region = "us-east-1"
}

# Create a security group to allow traffic to the ALB
resource "aws_security_group" "alb_sg" {
  name_prefix = "alb_sg"
  ingress {
    from_port = 80
    to_port = 80
    protocol = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

# Create an ALB and target group
resource "aws_lb" "alb" {
  name               = "example-alb"
  internal           = false
  load_balancer_type = "application"

  subnets = ["subnet-12345678", "subnet-87654321"]

  security_groups = [aws_security_group.alb_sg.id]

  tags = {
    Environment = "production"
  }
}

resource "aws_lb_target_group" "target_group" {
  name        = "example-target-group"
  port        = 80
  protocol    = "HTTP"
  vpc_id      = "vpc-12345678"

  health_check {
    path = "/health"
  }

  tags = {
    Environment = "production"
  }
}

# Create an autoscaling group
resource "aws_launch_configuration" "launch_configuration" {
  name_prefix   = "example-lc-"
  image_id      = "ami-12345678"
  instance_type = "t2.micro"

  # Other settings here (e.g. security groups, userdata, etc.)
}

resource "aws_autoscaling_group" "autoscaling_group" {
  name                      = "example-asg"
  launch_configuration      = aws_launch_configuration.launch_configuration.id
  target_group_arns         = [aws_lb_target_group.target_group.arn]
  health_check_type         = "EC2"
  min_size                  = 1
  max_size                  = 3
  desired_capacity          = 2
  vpc_zone_identifier       = ["subnet-12345678", "subnet-87654321"]
  termination_policies      = ["Default"]
  wait_for_capacity_timeout = "10m"

  tags = {
    Environment = "production"
  }
}
``` 
Note that you will need to customize the settings for your specific use case (e.g. specify your own AMI ID, VPC ID, subnet IDs, etc.). This is just an example to give you an idea of how to create an autoscaling group with an ALB in Terraform.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
