davidATsains commented 4 years ago

I am learning Terraform using this book. I am chapter 2 section: Deploy a single web server. i followed the code and everything. but when I curl the public ip:8080,
I have already tried curl http://elastic_instance_public_ip:8080 and curl https://elastic_instance_public_ip:8080

the result is Operation timed out How do I solve this issue.

Below is my code:

provider "aws" {
  version = "~>2.0"
  region  = "eu-west-1"

}

resource "aws_instance" "example" {
  ami                    = "ami-01f14919ba412de34"
  instance_type          = "t2.micro"
  vpc_security_group_ids = [aws_security_group.instance.id]

  user_data = <<-EOF
              #!/bin/bash
              echo "Hello Sainsburys" > index.html
              nohup busybox httpd -f -p 8080 &
              EOF

  tags = {
    Name = "test-example"
  }
}

resource "aws_security_group" "instance" {
  name = var.security_group_name

  ingress {
    from_port   = 8080
    to_port     = 8080
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

variable "security_group_name" {
  description = "The name of the security group"
  default     = "terraform-example-instance"
}
output "public_ip" {
  value = aws_instance.example.public_ip
  description = "The public IP of the instance"
}

You're running ami-01f14919ba412de34, which I believe is Amazon Linux. This AMI does not have busybox installed by default, so the User Data script is likely failing. You can most likely verify this by looking at the system log of your EC2 instance; it's a bit hard to dig it out, but it'll probably have an error about busybox not being found.

In the book, I use Ubuntu by default, so you may want to switch to that if you're going to use busybox.
