Vagrantでインスタンスを指定したVPC subnet配下で起動してEIPを割り当てる方法

指定したVPCのSubnetにvagrant up --provider=awsでインスタンスを起動する方法です。

現時点でvagrant-awsのREADME.mdに下記のようなことが書いてあったけど、動かなかったので

• README.md

associate_public_ip - If true, will associate a public IP address to an instance in a VPC.

• やってみた結果

AWS Provider:
* The following settings shouldn't exist: public_ip_address

・・・

• 対応

Issue読んでみるとelastic_ipパラメータがあるらしい

• subnet_idを指定する
• aws.elastic_ipパラメータをtrueにするとインスタンス起動時にEIPが割り当てられrます

# -*- mode: ruby -*-
# vi: set ft=ruby :
require 'yaml'
# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

attributes = YAML.load_file(".aws/config.yml")

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "dummy"
  config.omnibus.chef_version = :latest

  config.vm.provider :aws do |aws, override|
    aws.tags = attributes["aws_provider"]["tags"]
    aws.access_key_id = attributes["aws_provider"]["access_key_id"]
    aws.secret_access_key = attributes["aws_provider"]["secret_access_key"]
    aws.keypair_name = attributes["aws_provider"]["keypair_name"]
    aws.region = attributes["aws_provider"]["region"]
    aws.ami = "ami-99107d98" #suz_lab_centos-core-6.5.1
    aws.instance_type = attributes["aws_provider"]["instance_type"]
    aws.security_groups = attributes["aws_provider"]["security_groups"]
    aws.subnet_id = attributes["aws_provider"]["subnet_id"]
    aws.elastic_ip = true
    override.ssh.username = attributes["aws_provider"]["ssh_username"]
    override.ssh.private_key_path = attributes["aws_provider"]["ssh_private_key_path"]
  end
end

終わりです。
