instance count and volume attachement about terraform-aws-ec2-instance

[vukomir]

Hi @NFhbar

you can use the same variable when you specify the count number

module "ec2" {
  source                      = "../modules/ec2"
  instance_count              = "${var.fe_ec2_count}"
  name                        = "app"
  ami                         = "${var.fe_ec2_ami}"
  instance_type               = "t2.micro"
  subnet_id                   = ["${data.terraform_remote_state.vpc.private_subnets_id}"]
  vpc_security_group_ids      = ["${data.terraform_remote_state.vpc.sg_fe_id}"]
}

resource "aws_volume_attachment" "this_ec2" {
  count                       = ${var.fe_ec2_count}"
  device_name                 = "/dev/sdh"
  volume_id                   = "${element(aws_ebs_volume.this.*.id, count.index)}"
  instance_id                 = "${element(module.ec2_fe.id, count.index)}"
}

resource "aws_ebs_volume" "this" {
  count                       = ${var.fe_ec2_count}"
  availability_zone           = "${element(var.availability_zones, count.index)}"
  type                        = "gp2"
  size                        = 1
  
  tags                        = "${var.default_tags}"
  depends_on                  = ["module.ec2_fe"]
}
