amazon-web-services - 将 taskRoleArn 附加到 AWS Fargate 不起作用

Question

我正在尝试将 IAM 角色附加到 AWS Fargate 容器。没有错误，容器可以执行。但是，容器无法调用 AWS API。

从容器：

• 运行aws命令时，我得到了Unable to locate credentials 错误
• curl到http://169.254.169.254/latest/meta-data/iam/info不成功

我的任务定义：

}

我应该怎么做才能让它工作？谢谢。

具有相同的症状，awscli通过 pip 安装最新版本而不是使用打包版本解决了我的问题。

旧版本（例如 ubuntu trusty 中可用的版本）不支持从 Fargate 运行。
