ruby - describe_spot_price_history 返回的可用区 [eu-west-1a] 无效

Question

我使用的是 AWS Ruby 开发工具包，但发现一堆由 describe_spot_price_history 返回的错误消息。错误消息显示:无效可用区:eu-west-1a

此消息仅针对欧洲 (eu-west-1a...) 的可用区返回，而不会针对美国东部的其他可用区返回。你知道如何解决这个问题吗？谢谢!

这是我的 ruby 脚本:

begin
  ec2 = AWS::EC2.new(
    :access_key_id => access_key,
    :secret_access_key => access_secret)

  response = ec2.client.describe_spot_price_history(
    :start_time => start_time,
    :end_time => end_time,
    :instance_types => instance_type,
    :product_descriptions => 'Linux/UNIX',
    :availability_zone => availability_zone
  )

  prices = Array.new(response.spot_price_history_set.map(&:spot_price))
  prices = prices.flatten.collect { |i| i.to_f }
  puts prices

rescue
  puts "Error: " + $!
  exit 1
end

Answer 1

只需将ec2端点参数添加到EC2.new

  ec2 = AWS::EC2.new(
    :access_key_id => access_key,
    :secret_access_key => access_secret,
    :ec2_endpoint => 'ec2.eu-west-1.amazonaws.com')
