ALB does not redirect HTTP requests into HTTPS ones

Description

Ensure that the behaviour of the Load balancer is redirect any traffic from the encrypted endpoint rather than handling on http or failing to respond.

• Resource: aws_lb, aws_lb_listener
• Argument: redirect of aws_lb_listener

resource "aws_lb" "lb_good" {
}


resource "aws_lb_listener" "listener_good" {
  load_balancer_arn = aws_lb.lb_good.arn
  port              = "80"
  protocol          = "HTTP"

  default_action {
    type = "redirect"

    redirect {
      port        = "443"
      protocol    = "HTTPS"
      status_code = "HTTP_301"
    }

  }
}
