Is there health check url I can use in Boundary?

Hi, I’m trying to attach ALB to Boundary Controllers. However, I can’t find a API that I can use as a health check path. Any suggestions ?

resource "aws_lb" "boundary" {
  name               = "boundary"
  load_balancer_type = "application"
  internal           = false
  subnets            = data.terraform_remote_state.network.outputs.tokyo_vpc_main.public_subnet_ids

}

resource "aws_lb_listener" "boundary_http" {
  load_balancer_arn = aws_lb.boundary.arn
  port              = "80"
  protocol          = "HTTP"

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

resource "aws_lb_listener" "boundary_https" {
  load_balancer_arn = aws_lb.boundary.arn
  port              = "443"
  protocol          = "HTTPS"
	ssl_policy        = "ELBSecurityPolicy-2016-08"
	certificate_arn   = "MYARN"

  default_action {
    type             = "forward"
		target_group_arn = aws_lb_target_group.boundary.arn
  }
}

resource "aws_lb_target_group" "boundary" {
  name     = "boundary"
  port     = 9200
  protocol = "HTTP"
  vpc_id   = data.terraform_remote_state.network.outputs.tokyo_vpc_main.vpc_id
}

resource "aws_lb_target_group_attachment" "boundary" {
  count            = var.num_controllers
  target_group_arn = aws_lb_target_group.boundary.arn
  target_id        = aws_instance.controller[count.index].id
  port             = 9200
}

resource "aws_security_group" "controller_lb" {
  vpc_id = data.terraform_remote_state.network.outputs.tokyo_vpc_main.vpc_id

}

resource "aws_security_group_rule" "allow_9200" {
  type              = "ingress"
  from_port         = 9200
  to_port           = 9200
  protocol          = "tcp"
  cidr_blocks       = ["0.0.0.0/0"]
  security_group_id = aws_security_group.controller_lb.id
}

We don’t have a steadfast health check endpoint yet, but you can use the root path on the controller API server as we do here.
