问题描述
我正在创建 EC2 实例和多个不同大小的 EBS 卷。下面给出了创建相同的 terraform 脚本。
resource "aws_ebs_volume" "ebs_volume" {
for_each = {
0 = var.influxdb_data_volume_size
1 = var.influxdb_wal_volume_size
2 = var.telegraf_volume_size
3 = var.grafana_volume_size
4 = var.data_volume_size
}
availability_zone = var.availability_zone
size = each.value
type = "gp2"
tags = {
name = "${var.tag}-ebs-volume"
billing = var.tag
}
}
# section for the EBS volume attachment
resource "aws_volume_attachment" "volume_attachement" {
count = var.ebs_volume_count
volume_id = aws_ebs_volume.ebs_volume[count.index].id
device_name = "${element(var.ec2_device_names,count.index)}"
instance_id = aws_instance.ec2_production.id
}
# section for the aws_key_pair
resource "aws_key_pair" "key_pair" {
key_name = "${var.tag}-key-pair"
public_key = var.key_pair
tags = {
name = "${var.tag}-key-pair"
billing = var.tag
}
}
resource "aws_instance" "ec2_production" {
# count = "${var.ec2_instance_count}"
ami = var.ami
availability_zone = var.availability_zone
instance_type = var.ec2_instance_type
subnet_id = aws_subnet.subnet.id
associate_public_ip_address = true
vpc_security_group_ids = [aws_security_group.security_group_access_internet.id]
# disable_api_termination = true
key_name = "${var.tag}-key-pair"
ebs_block_device {
device_name = "/dev/sda1"
volume_type = "gp2"
volume_size = var.root_volume_size
}
tags = {
name = "${var.tag}-ec2"
billing = var.tag
}
}
aws_instance 资源中定义的卷是大小为 40GB 的根卷，我正在 aws_ebs_volume 资源中创建多个不同大小的卷。
现在我试图通过更新 variable.tf 文件将根卷的大小从 40GB 更改为 60GB。
当我使用 terraform plan 命令时，它会创建 6 个资源并销毁 6 个资源，其中包括 EBS 卷和 EC2 实例。
现在，我想增加任何根卷或任何其他重新创建或销毁任何内容的卷的大小。
下面我给出了 terraform plan

Plan: 6 to add,0 to change,6 to destroy.
有什么方法可以在不破坏任何东西的情况下实现更新卷大小吗？
