Amazon CLI 与 Bash 脚本一起使用的 IAM 示例

以下代码示例向您展示了如何使用 Amazon Command Line Interface 带有 IAM 的 with Bash 脚本来执行操作和实现常见场景。

操作是大型程序的代码摘录,必须在上下文中运行。您可以通过操作了解如何调用单个服务函数,还可以通过函数相关场景和跨服务示例的上下文查看操作。

场景是展示如何通过在同一服务中调用多个函数来完成特定任务任务的代码示例。

每个示例都包含一个指向的链接 GitHub,您可以在其中找到有关如何在上下文中设置和运行代码的说明。

场景

以下代码示例展示了如何创建用户并代入角色。

警告

为了避免安全风险,在开发专用软件或处理真实数据时,请勿使用 IAM 用户进行身份验证,而是使用与身份提供商的联合身份验证,例如 Amazon IAM Identity Center

  • 创建没有权限的用户。

  • 创建授予列出账户的 Amazon S3 存储桶的权限的角色

  • 添加策略以允许用户代入该角色。

  • 代入角色并使用临时凭证列出 S3 存储桶,然后清除资源。
