我目前正在开发一个在 AWS 基础设施上运行的节点应用程序,它可以访问 DynamoDB 和 SSM。
我对 Node 的熟练程度不足以创建 MVCE,但这些都是与我相关的部分:
const AWS = require('aws-sdk')
AWS.config.update({ region: 'eu-west-1' })
const ddb = new AWS.DynamoDB.DocumentClient()
const ssm = new AWS.SSM()
const ssmQueryParams = {
Name: '/foo/bar/tablename',
WithDecryption: true
}
let ssmQueryResult
ssmQueryResult = (await ssm.getParameter(ssmQueryParams).promise())
const tableName = ssmQueryResult.Parameter.Value
const ddbParams = {
TableName: tableName,
Key: {
'foo_id': fooId
}
}
const ddbQueryResult = (await ddb.get(ddbParams).promise())
所以我想从 SSM 获取 DynamoDB 表名。如果我删除 SSM 部分,则代码有效。但有了它,我得到
{ Error: connect EHOSTUNREACH 169.123.123.123:80
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1097:14)
message: 'Missing credentials in config',
errno: 'EHOSTUNREACH',
code: 'CredentialsError',
syscall: 'connect',
address: '169.123.123.123',
port: 80,
time: 2019-06-25T12:34:02.909Z,
originalError:
{ message: 'Could not load credentials from any providers',
errno: 'EHOSTUNREACH',
code: 'CredentialsError',
syscall: 'connect',
address: '169.123.123.123',
port: 80,
time: 2019-06-25T12:34:02.909Z,
originalError:
{ errno: 'EHOSTUNREACH',
code: 'EHOSTUNREACH',

address: '169.123.123.123',
port: 80,
message: 'connect EHOSTUNREACH 169.123.123.123:80' } } }
那么,为什么我可以访问 DynamoDB 上的数据,但是当我想从 SSM 读取数据时,却出现凭据错误?
编辑:添加accessKeyId
和secretAccessKey
到AWS.config.update
不是一种选择。
