启动源实例时出错：InvalidBlockDeviceMapping：大小为 8GB 的​​卷小于快照

Question

我在使用 terraform-aws-service-catalog 中的 ec2-instance gruntwork 模块启动单个 ec2 实例（现有 AMI 的卷大小 = 32GB）时遇到了一个问题。它不允许创建具有给定快照 ID（大小=32GB）的根卷。启动ec2实例时弹出错误-

module.demo_instance.module.ec2_instance.aws_instance.instance: Creating...
Error: Error launching source instance: InvalidBlockDeviceMapping: Volume of size 8GB is smaller than  snapshot 'snap-0850762dcfacpb2957', expect size >= 32GBB
  on .terraform/modules/demo_instance.ec2_instance/modules/single-server/main.tf line 23, in resource "aws_instance" "instance":
  23: resource "aws_instance" "instance" {

我看到 ec2 实例正在使用来自 terraform-aws-server 的单服务器模块，它的默认 root_volume_size 为 8GB，无法从 ec2-instance 模块修改。我试图附加到 ec2 实例的 ebs_volume 似乎不起作用

module "demo_instance" {
      source = "git::git@github.com:gruntwork-io/terraform-aws-service-catalog.git//modules/services/ec2-instance?ref=v0.44.5"
    
      name          = "${var.name}-${var.account_name}"
      instance_type = var.instance_type
    
      ami = "ami-03a0a2de6ce3aq7ff7"
      
      ami_filters = null
    
    
      enable_ssh_grunt = false
      keypair_name     = local.key_pair_name
    
      vpc_id    = var.vpc_id
      subnet_id = var.subnet_ids[0]
      
    
      ebs_volumes = {
        "demo-volume" = {
          type        = "gp2"
          size        = 32
          snapshot_id = "snap-0850762dcfacpb2957"    
        },
      }
      
      allow_ssh_from_cidr_blocks = var.allow_ssh_from_cidr_list
    
      allow_ssh_from_security_group_ids  = []
      allow_port_from_cidr_blocks        = {}
      allow_port_from_security_group_ids = {}
    
      route53_zone_id            = ""
      dns_zone_is_private        = true
      route53_lookup_domain_name = ""
    }

有没有办法使用 ec2-instance gruntwork 模块修改 root_volume_size 的默认值（8GB）？任何帮助将不胜感激。

Gruntwork 就该问题提出了issue。 size 未在 ec2-instance 模块中公开。同时single-server模块可以直接使用。
