Public IP not coming in instances from Terraform code

问题

要求上述代码如下所示：

公司希望体系结构具有以下服务：

  1. 创建具有VPC、2个子网和每个子网中的1个实例的模板。
  2. 将安全组、互联网网关和网络接口附加到实例。

以下是 Terraform 代码，未在实例中获取公共 IP：

  1.  # 块设置
  2.     terraform {

所有的东西都被创建，但 EC2 实例没有获取公共 IP。如果我在实例下使用以下代码：

  1. resource "aws_instance" "TF_instance1" {
  2.   ami                         = "ami-024e6efaf93d85776"
  3.   instance_type               = "t2.micro"
  4.   associate_public_ip_address = true ## <-- 添加此行
  5.   key_name                    = "assign.ohio"
  6.   network_interface {
  7.     network_interface_id = aws_network_interface.TF_NI1.id
  8.     device_index         = 0
  10.   }
  11.   tags = {
  12.     Name = "TF_instance1"
  13.   }
  14. }

会出现以下错误：

  1. 错误：冲突的配置参数

你需要在你的EC2实例上关联公共IP，示例如下：

  1. resource "aws_instance" "TF_instance2" {
  2.   ami                         = "ami-024e6efaf93d85776"
  3.   instance_type               = "t2.micro"
  4.   associate_public_ip_address = true ## <-- 添加这一行
  5.   key_name                    = "assign.ohio"
  6.   network_interface {
  7.     network_interface_id = aws_network_interface.TF_NI2.id
  8.     device_index         = 0
  9.   }
  10.   tags = {
  11.     Name = "TF_instance2"
  12.   }
  13. }

查看文档以供参考。

英文:

You need to associate public IP on your EC2 instance, example below:

  1. resource &quot;aws_instance&quot; &quot;TF_instance2&quot; {
  2. ami                         = &quot;ami-024e6efaf93d85776&quot;
  3. instance_type               = &quot;t2.micro&quot;
  4. associate_public_ip_address = true ## &lt;-- Add this
  5. key_name                    = &quot;assign.ohio&quot;
  6. network_interface {
  7. network_interface_id = aws_network_interface.TF_NI2.id
  8. device_index         = 0
  9. }
  10. tags = {
  11. Name = &quot;TF_instance2&quot;
  12. }
  13. }

Check the docs for reference.

以下是翻译好的部分：

  • 如果您能ping一下您收到的错误，那将是很好的。
  • 或者，您可以创建弹性 IP 并附加到实例上。
  • 尝试以下代码：
  1. resource "aws_instance" "TF_instance2" {
  2.   ami                         = "ami-024e6efaf93d85776"
  3.   instance_type               = "t2.micro"
  4.   associate_public_ip_address = true ## <-- 添加这一行
  5.   key_name                    = "assign.ohio"
  6.   network_interface {
  7.     network_interface_id = aws_network_interface.TF_NI2.id
  8.     device_index         = 1
  9.   }
  10.   tags = {
  11.     Name = "TF_instance2"
  12.   }
  13. }

请注意，我已将HTML实体编码（如"）还原为原始文本。

英文:

It would be good if you ping the error you are receiving.
Alternatively, you can create Elastic IP and attach to the instance.

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/eip

Try the below code:

  1. resource &quot;aws_instance&quot; &quot;TF_instance2&quot; {
  2. ami                         = &quot;ami-024e6efaf93d85776&quot;
  3. instance_type               = &quot;t2.micro&quot;
  4. associate_public_ip_address = true ## &lt;-- Add this
  5. key_name                    = &quot;assign.ohio&quot;
  6. network_interface {
  7. network_interface_id = aws_network_interface.TF_NI2.id
  8. device_index         = 1
  9. }
  10. tags = {
  11. Name = &quot;TF_instance2&quot;
  12. }
  13. }
