Packer 无法与 AWS 实例通信

Question

我只是在玩打包机，我创建了一个简单的模板，如下所示：

{
  "variables": {
    "aws_access_key": "{{env `AWS_ACCESS_KEY`}}",
    "aws_secret_key": "{{env `AWS_SECRET_KEY`}}"
  },
  "builders": [
    {
      "type": "amazon-ebs",
      "access_key": "{{user `aws_access_key`}}",
      "secret_key": "{{user `aws_secret_key`}}",
      "region": "us-east-1",
      "vpc_id": "MY_DEFAULT_VPC_ID",
      "subnet_id": "MY_PUBLIC_SUBNET_ID",
      "source_ami": "ami-a025aeb6",
      "instance_type": "t2.micro",
      "ssh_username": "ubuntu",
      "ami_name": "packer-example {{timestamp | clean_resource_name}}"
    }
  ]
}

当我运行 packer build initial_ami.json 我得到以下错误。

amazon-ebs: output will be in this color.

==> amazon-ebs: Prevalidating any provided VPC information
==> amazon-ebs: Prevalidating AMI Name: packer-example 1628354042

==> Wait completed after 6 minutes 51 seconds

==> Some builds didn't complete successfully and had errors:

==> Builds finished but no artifacts were created.

所以一切正常，直到它尝试连接实例的 ssh 端口。它似乎正在使用 172.... IP，所以我认为它不会连接到实例。我的问题是：

这个问题是不是因为 packer 正在创建一个没有 public IP 的实例？
如果是这样，那么我如何强制加壳器创建一个具有 public IP 的实例，然后使用该 public IP 连接到 ssh 服务？

Answer 1

好的，我明白了，我们需要做的就是设置：

"associate_public_ip_address": true 在模板文件的构建器部分。

Answer 2

我建议您在构建 Packer 映像时不要使用 public IP，而是将 ssh_interface 设置为 private_ip，这样如果您将它用作ci/cd 流程的一部分，否则如果您更频繁地构建它们，您将收取大量数据传输成本
