Question

Amazon EC2定价api为每种类型的定价提供不同的属性，我如何知道我的ec2实例在哪个定价下运行。因为在定价api即json文件时，amazon提供的属性很少，并且在这些属性之外我只能从实例内部获取instanceType。如何获得其他人？

var titles: [String] = ["Title1", "Title2", "Title3"]


override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell 
{
   let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! CustomCollectionViewCell
   cell.titleLabel.text = self.titles[indexPath.row]
   cell.subtitleLabel.text = "Choose to start"
   cell.layer.cornerRadius = 10

   return cell
}

Answer 1

1）找到您的实例大小和AZ。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）拉出正确的文件以获得EC2的定价，例如目前 https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonEC2/current/index.json

3）在此文件中有＆＃34;产品＆＃34;。因此，例如在产品中找到eu-west的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"
  }
},

请注意此产品的SKU

4）接下来找到＆＃34;术语＆＃34; json文件中的部分。有＆＃34; OnDemand＆＃34;的部分。和＆＃34;保留＆＃34;。 In＆＃34; OnDemand＆＃34;一次提到感兴趣的产品的SKU（在上面的示例中为SYEPG42MVWFMUBT6）。在＆＃34;保留＆＃34;有几个条目有不同的术语

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等工具或json处理库，如python中包含的那样

从内部实例查询amazon ec2属性以检查定价
