Connecting to AWS EC2 with terraform and execute commands

Question

I'm new to infrastructure. I'm trying to create an EC2 instance and execute commands using Terraform provisioners. However, when I apply the Terraform configuration, it times out.

$ ssh_keygen -f ./example -m PEM // this generate example.pub and example

provider "aws" {
  region = "us-west-2"
}

resource "aws_key_pair" "example" {
  key_name   = "keypair"
  public_key = file("./example.pub")
  tags = {
    Name = "Example Key Pair"
  }
}

resource "aws_instance" "web" {
  ami           = "ami-003634241a8fcdec0"
  instance_type = "t2.micro"
  key_name      = aws_key_pair.example.key_name
  tags = {
    Name = "Example EC2"
  }

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

  provisioner "file" {
    content     = "Hello World!"
    destination = "/home/ubuntu/example.txt"
  }

}

Answer 1

can you please add the following:

provisioner "file" {
source      = "example.txt"              # terraform machine
destination = "/home/ubuntu/example.txt" # remote machine
}

before:

provisioner "file" {
    content     = "Hello World!"
    destination = "/home/ubuntu/example.txt"
  }

where "example.txt" is an empty file available on your Terraform machine?

Does it hangs as well?
