## VPCを作成して削除するまでの流れを記載したもので、スクリプトではないので注意して下さい
require 'aws-sdk'
ACCESS_KEY = 'set your access key'
SECRET_KEY = 'set your secret key'
EC2_REGION = 'ec2.ap-southeast-1.amazonaws.com'
 
ec2 = AWS::EC2.new(
  :access_key_id => ACCESS_KEY,

).client

vpc_cidr = '10.0.0.0/16'
subnet_a = '10.0.1.0/24'
subnet_b = '10.0.2.0/24'

## VPCのCIDRを作成します
ec2.create_vpc(:cidr_block => vpc_cidr, :instance_tenancy => 'default')
 => {:request_id=>"afcd2cd2-07ce-4714-858b-2e45c800d514", :vpc=>{:tag_set=>[], :vpc_id=>"vpc-662d2c0f", :state=>"pending", :cidr_block=>"10.0.0.0/16", :dhcp_options_id=>"dopt-7a2d2c13", :instance_tenancy=>"default"}} 

## デフォルトでルートテーブルが割り当てられます
ec2.describe_route_tables[:route_table_set]
 => [{:route_set=>[{:destination_cidr_block=>"10.0.0.0/16", :gateway_id=>"local", :state=>"active", :origin=>"CreateRouteTable"}], :association_set=>[{:route_table_association_id=>"rtbassoc-7b2d2c12", :route_table_id=>"rtb-782d2c11", :main=>true}], :tag_set=>[], :propagating_vgw_set=>[], :route_table_id=>"rtb-782d2c11", :vpc_id=>"vpc-662d2c0f"}] 

## DHCPオプションもVPC作成時に割り当てられます
ec2.describe_dhcp_options[:dhcp_options_set]
 => [{:dhcp_configuration_set=>[{:value_set=>[{:value=>"ap-southeast-1.compute.internal"}], :key=>"domain-name"}, {:value_set=>[{:value=>"AmazonProvidedDNS"}], :key=>"domain-name-servers"}], :tag_set=>[], :dhcp_options_id=>"dopt-7a2d2c13"}]
