从内部实例查询 amazon ec2 属性以检查定价

Question

Amazon EC2 定价 api 为每种定价类型提供不同的属性，我如何知道我的 ec2 实例在哪种定价下运行。因为在定价 api 即 json 文件中，亚马逊提供了很少的属性，并且在这些属性中，我只能从实例内部获取 instanceType。怎么搞定别人？

Answer 1

1) 找到您的实例大小和可用区。例如

[ec2-user@ip-10-50-1-171 temp]$ ec2-metadata |grep placement
placement: eu-west-1a
[ec2-user@ip-10-50-1-171 temp]$ ec2-metadata |grep instance-type
instance-type: t2.micro

2) 为 EC2 的定价提取正确的文件，例如目前 https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonEC2/current/index.json

3) 在这个文件中有“产品”。因此，例如在产品中为 eu-west 找到一个 t2.micro

"SYEPG42MVWFMUBT6" : {
  "sku" : "SYEPG42MVWFMUBT6",
  "productFamily" : "Compute Instance",
  "attributes" : {
    "servicecode" : "AmazonEC2",
    "location" : "EU (Ireland)",
    "locationType" : "AWS Region",
    "instanceType" : "t2.micro",
    "instanceFamily" : "General purpose",
    "vcpu" : "1",
    "physicalProcessor" : "Intel Xeon Family",
    "clockSpeed" : "Up to 3.3 GHz",
    "memory" : "1 GiB",
    "storage" : "EBS only",
    "networkPerformance" : "Low to Moderate",
    "processorArchitecture" : "32-bit or 64-bit",
    "tenancy" : "Shared",
    "operatingSystem" : "SUSE",
    "licenseModel" : "No License required",
    "usagetype" : "EU-BoxUsage:t2.micro",
    "operation" : "RunInstances:000g",
    "preInstalledSw" : "NA",
    "processorFeatures" : "Intel AVX; Intel Turbo"
  }
},

记下此产品的 SKU

4) 接下来在 json 文件中找到“terms”部分。有“按需”和“保留”部分。在“OnDemand”中，感兴趣的产品的 SKU（在上面的示例中为 SYEPG42MVWFMUBT6）被提及一次。在“保留”中有几个条目具有不同的术语

如果您需要以编程方式执行所有这些步骤，则必须使用 shell 脚本和 jq 之类的工具或用于 json 处理的库（例如 python 附带的库）
