node.js - AWS 通过 api 网关添加实例

问题描述

所以我在 Lambda 中有函数。函数连接到 api 网关，它应该添加 EC2 实例。当我通过 api gateway 方法测试到达端点时，它返回状态 200 但没有添加任何实例。也许实例参数是错误的？基本上该功能是文档示例的修改版本。

var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-2'});

exports.handler = function index(event, context, callback) {
    // Load the AWS SDK for Node.js

// Load credentials and set region from JSON file

// Create EC2 service object
var ec2 = new AWS.EC2({apiVersion: '2016-11-15'});

// AMI is amzn-ami-2011.09.1.x86_64-ebs
var instanceParams = {
   InstanceType: 't2.micro',
   KeyName: 'firstkeypair',
   ImageId: 'ami-0bbe28eb2173f6167'
};

// Create a promise on an EC2 service object
var instancePromise = new AWS.EC2({apiVersion: '2016-11-15'}).runInstances(instanceParams).promise();

// Handle promise's fulfilled/rejected states
instancePromise.then(
  function(data) {
    console.log(data);
    var instanceId = data.Instances[0].InstanceId;
    console.log("Created instance", instanceId);
    // Add tags to the instance
    tagParams = {Resources: [instanceId], Tags: [
       {
          Key: 'Name',
          Value: 'SDK Sample'
       }
    ]};
    // Create a promise on an EC2 service object
    var tagPromise = new AWS.EC2({apiVersion: '2016-11-15'}).createTags(tagParams).promise();
    // Handle promise's fulfilled/rejected states
    tagPromise.then(
      function(data) {
        console.log("Instance tagged");
      }).catch(
        function(err) {
        console.error(err, err.stack);
      });
  }).catch(
    function(err) {
    console.error(err, err.stack);
  });
}

编辑： 通过向 Lambda 函数添加 EC2 完全访问权限来解决。
