Terraform volume tags changes on alternate run if defined in both aws_instance and aws_ebs_volume resources

[saveshnshetty]

Hi team,
I've defined volume tags in aws_instance resource and aws_ebs_volume resource since I need to add tags to root volume also. But when I ran "terraform apply" second time. Ebs volumes tags got replaced with aws instance volume tags. On third run it got replaced with original ebs volume tags .
This tags changes alternatively . Can you please look into it .

syntax :
resource "aws_instance" "app" {
count = "1"
ami = "${lookup(var.ami,var.region)}"
ebs_optimized = "${var.ebs_optimized}"
instance_type = "${var.instance_type_app}"
monitoring = "${var.monitoring}"
key_name = "${var.key_name}"
user_data = "${data.template_file.userdata-app..rendered[count.index]}"
network_interface {
network_interface_id = "${element(aws_network_interface.network-interface-app..id, count.index)}"
device_index = 0
}
tags {
Name = "$app-${count.index + 1}"
Type = "app"
Env = "${var.env}"
Customer_id = "${var.customer_id}"
}

	root_block_device {
		volume_type           = "${var.root_volume_type}"
		volume_size           = "${var.root_volume_size}"
		delete_on_termination = "${var.root_delete_on_termination}"
	}


	volume_tags {
		Name                  = "${var.env}-s4hana-app-${count.index + 1}"
		Type                  = "root-volume"
		Env                   = "${var.env}"
        Customer_id           = "${var.customer_id}"
	}

}

resource "aws_ebs_volume" "ebs-app" {
count = "${var.app_count}"
availability_zone = "****"
size = "${var.ebs_volume_size[0]}"
type = "${var.ebs_volume_type[0]}"
tags {
Name = "app-tmp"
Type = "ebs-volume"
Env = "${var.env}"
Customer_id = "${var.customer_id}"
}
}
