i see. i have not tested it, but theoretically you can do something like that:

  1. create a bash script to get ip:
#!/usr/bin/env bash
echo '{"result":"'$(curl'"}'
Enter fullscreen mode Exit fullscreen mode
  1. use the script as data source in tf file:
data "external" "script" {
  program = ["bash", "./"] // is your script name

resource "aws_security_group" "ubuntu" {
  name        = "ubuntu-security-group"
  description = "Allow SSH only for"

  ingress {
    description = "SSH"
    from_port   = 22
    to_port     = 22
    protocol    = "tcp"
    cidr_blocks = ["${data.external.script.result}/32"]

Enter fullscreen mode Exit fullscreen mode
