在节点中使用AWS JS SDK来描述所有ec2实例

我一直在node中使用AWS JS SDK，并且我想描述所有地区的现有ec2 istances，但我得到一个空的reservation[]。我试图用 AWS.config.update{}指定一个区域，它按预期工作，它返回实例，但这是我想要的。我想查询AWS的所有实例，而不指定区域。有一个简单的方法！？（我用我的智能手机问这个问题，我现在无法访问我的电脑）。在节点中使用AWS JS SDK来描述所有ec2实例

谢谢你的帮助。

您必须遍历每个区域，并为每个区域调用一次。 API是区域特定的，您无法在单个API调用中获取所有区域中的所有EC2实例的列表。

根据Amazon Web Services docs，

例如，如果需要访问多个区域亚马逊EC2对象，创建针对每个区域的EC2服务对象，然后相应地设置每一个服务对象的区域配置。

var ec2_regionA = new AWS.EC2({region: 'ap-southeast-2', maxRetries: 15, apiVersion: '2014-10-01'}); 
var ec2_regionB = new AWS.EC2({region: 'us-east-1', maxRetries: 15, apiVersion: '2014-10-01'});

我的实现，

var AWS = require('aws-sdk'); 
 

 
var EC2Objects = [ 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'us-east-1'}),  //N. Virginia 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'us-east-2'}),  //Ohio 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'us-west-1'}),  //N. California 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'us-west-2'}),  //Oregon 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ca-central-1'}), //Canada (Central) 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'eu-west-1'}),  //Ireland 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'eu-central-1'}), //Frankfurt 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'eu-west-2'}),  //London 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ap-northeast-1'}), //Tokyo 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ap-northeast-2'}), //Seoul 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ap-southeast-1'}), //Singapore 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ap-southeast-2'}), //Syndney 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'ap-south-1'}),  //Mumbai 
 
    new AWS.EC2({apiVersion: '2016-11-15',region: 'sa-east-1'})  //Sao Paulo 
 
]; 
 

 
var instances = []; 
 
listEc2(); 
 

 
function listEc2(){ 
 
    var params = {}; 
 
    for(var i=0; i<EC2Objects.length; i++){ 
 
     EC2Objects[i].describeInstances(params, function(err, data) { 
 
      if (err) console.log(err, err.stack); // an error occurred 
 
      else  ec2ListBuilderCallback(data);   // successful response 
 
     }); 
 
    } 
 
} 
 

 
function ec2ListBuilderCallback(data){ 
 
    instances.push(data); 
 
    if(instances.length == EC2Objects.length){ 
 
     console.log(JSON.stringify(instances)); 
 
    } 
 
}

OUTPUT：

[{"Reservations":[]},{"Reservations":[{"ReservationId":"r-0e7c0a2e3cf30944c","Groups":[],"Instances":[{"InstanceId":"i-0391f0e44b04675ad","ImageId":"ami-0b33d91d","State":{"Code":16,"Name":"running"}],{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]},{"Reservations":[]}]

我切断了我使用的，因为它是很长的区域输出。
