javascript – AWS Lambda无法连接到RDS实例,但我可以在本地吗？

我正在尝试从lambda连接到我的RDS实例.我在本地写了lambda并在本地测试,一切都很好用.我部署到lambda,突然它不起作用.下面是我正在运行的代码,如果有帮助,我将通过kinesis流调用lambda.

'use strict';

exports.handler = (event, context, handlerCallback) => {
    console.log('Recieved request for kinesis events!');
    console.log(event);
    console.log(context);

    const connectionDetails = {
        host:     RDS_HOST,
        port:     5432,
        database: RDS_DATABASE,
        user:     RDS_USER,
        password: RDS_PASSWORD
    };

    const db = require('pg-promise')({promiseLib: require('bluebird')})(connectionDetails);

    db
            .tx(function () {
                console.log('Beginning query');

                return this.query("SELECT 'foobar'")
                           .then(console.log)
                           .catch(console.log)
                           .finally(console.log);
            })
            .finally(() => handlerCallback());
};

以下是云监视的日志,如果它有帮助：

解决方法:

@MarkB @ Michael-sqlbot在评论中是正确的,这是一个安全组问题.

我终于获得了AWS支持响应,指出RDS安全组确实是特定IP的私有.这没有意义,因为我从未配置过,我可以从本地机器和弹性beanstalk访问数据库.我将0.0.0.0/0添加到安全组,现在lambda可以连接.谢谢你的帮助！
