Overview

This cop warns against an ingress rule from 0.0.0.0/0 on port 22 (SSH). That is a Very Bad Idea™.

# bad
resource "aws_launch_configuration" "lc" {}

resource "aws_autoscaling_group" "asg" {
  launch_configuration = aws_launch_configuration.lc.name
}

# good
resource "aws_launch_template" "tpl" {}

resource "aws_autoscaling_group" "asg" {
  launch_template {
    id      = aws_launch_template.tpl.id
    version = "$Latest"
  }
}
