我有这个代码:

const uploadAllToS3 = () => {
    console.log("upload useless file to s3, just to test access rights");
    new AWS.S3().putObject({
        Bucket: scheduledJobsConstants.s3BucketName(),
        Key: `test/${new Date()}.txt`, Body: "Hello!",
    }, (err) => {
        console.log(`env:${inspect(process.env)}
        provider:${AWS.CredentialProviderChain.defaultProviders}
        cred:${inspect(AWS.config.credentials)}
        err:${inspect(err)}`.replace(/(\r\n|\n|\r)/gm, ""));
    });
};

当这段代码在 ecs 中运行时(它假设一个可以访问 S3 存储桶的角色),我会在日志中得到这个:

日志的 env 部分:

env: {
    PATH: '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin',
    HOSTNAME: '485bbd95f87d',
    AWS_CONTAINER_CREDENTIALS_RELATIVE_URI: '/v2/credentials/be3d4d7c-28b6-47e6-8081-cd746d95cb28',
    ECS_CONTAINER_METADATA_FILE: '/opt/ecs/metadata/8c0b731d-49ce-4e19-bf79-64087b433876/ecs-container-metadata.json',
    NODE_VERSION: '8.9.4',
    YARN_VERSION: '1.3.2',
    NPM_CONFIG_PROGRESS: 'false',
    HOME: '/root'
  }

“AWS_CONTAINER_CREDENTIALS_RELATIVE_URI”存在于环境变量中,所以我认为 sdk 应该能够获取它。

日志的提供者部分只是 sdk 代码中定义的 4 个函数,如果在 env var 中看到“AWS_CONTAINER_CREDENTIALS_RELATIVE_URI”,则其中第 4 个函数将返回“ECSCredentials”。

奇怪的是,日志的 cred 部分在 ECS 中是“null”。当我在本地运行它时(我手动承担一个角色),日志的 cred 部分是“EnvironmentCredentials”,并且文件被上传到 S3。

日志的错误部分是:

我的代码或环境变量有什么问题吗?

我应该打印更多日志以帮助诊断此问题吗?

请指教,谢谢。

==========更新==========

我已经在 ECS 中运行了这段代码 const curlCommand = `curl http://169.254.170.2${process.env.AWS_CONTAINER_CREDENTIALS_RELATIVE_URI}`; exec(curlCommand, (error, stdout, stderr) => { console.log(`${curlCommand} err:${error} out:${stdout} stderr:${stderr}`); });

我得到的结果是: { "SecretAccessKey": "long string", "Token": "very long string", "Expiration": "2018-01-14T08:55:04+0000", "AccessKeyId": "shorted string" }

因此,如果 sdk 调用了http://169.254.170.2 ${process.env.AWS_CONTAINER_CREDENTIALS_RELATIVE_URI},它应该得到正确的响应。

简单的答案是做

AWS.config.credentials = new AWS.ECSCredentials(options);

大概是因为 aws-sdk 凭据的凭据未正确配置/配置。

尝试使用AWS.ECSCredentials.getgetPromise确保在使用凭据之前已加载它们:

const ecsCredentials = new AWS.ECSCredentials({ ... });
await ecsCredentials.getPromise();
AWS.config.credentials = ecsCredentials;
