查询从 AWS 定价 API 启动实例的成本

Question

我正在使用 AWS 定价 API：

http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/price-changes.html

问题是它有这样的数据

"KV46EU5KJGKB53ZX" : {
  "sku" : "KV46EU5KJGKB53ZX",
  "productFamily" : "Compute Instance",
  "attributes" : {
    "servicecode" : "AmazonEC2",
    "location" : "US East (N. Virginia)",
    "locationType" : "AWS Region",

我不知道如何将locationType和location与我用于启动 EC2 实例的数据相关联（例如在 us-east-1 中）。

有没有办法知道启动 EC2 实例的成本？

Answer 1

我不知道

价目表 API 提供的结构中存在这种交叉引用/映射数据，不幸的是，EC2 API 中的 DescribeRegions 也没有提供这些数据。

但是，在常规文档下的"区域和终端节点"页面上，很容易找到它。 根据该信息，您可以构建一个简单的字典或查找表。

Answer 2

我建议jq处理大型json文档。例如，对于 SKU KV46EU5KJGKB53ZX的按需定价：

curl -s https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonEC2/current/index.json 
 | jq .terms.OnDemand.KV46EU5KJGKB53ZX

给

{
  "KV46EU5KJGKB53ZX.JRTCKXETXF": {
    "offerTermCode": "JRTCKXETXF",
    "sku": "KV46EU5KJGKB53ZX",
    "effectiveDate": "2016-12-01T00:00:00Z",
    "priceDimensions": {
      "KV46EU5KJGKB53ZX.JRTCKXETXF.6YS6EN2CT7": {
        "rateCode": "KV46EU5KJGKB53ZX.JRTCKXETXF.6YS6EN2CT7",
        "description": "$0.156 per Dedicated RHEL m1.medium Instance Hour",
        "beginRange": "0",
        "endRange": "Inf",
        "unit": "Hrs",
        "pricePerUnit": {
          "USD": "0.1560000000"
        },
        "appliesTo": []
      }
    },
    "termAttributes": {}
  }
}

只是自己构建的。我知道它不会更新，但是...

注意：我从 AWS 定价用户界面中提取的此列表中缺少中国
