使用进行设置 AWS Config 的先决条件 AWS CLI

在设置 AWS 之前 AWS CLI,您需要创建一个 Amazon S3 存储桶、一个 Amazon SNS 主题和一个将附加策略作为先决条件的IAM角色。然后,您可以使用 AWS CLI 为指定存储桶、主题和角色 AWS Config。请按照以下步骤设置 AWS Config的先决条件。

步骤 1:创建 Amazon S3 存储桶

如果您的账户中已存在 Amazon S3 存储桶,并且您想使用该存储桶,请跳过此步骤并转至 第 2 步:创建 Amazon SNS 主题

创建存储桶
  1. 打开 Amazon S3 控制台,网址为https://console.aws.amazon.com/s3/

  2. 选择创建存储桶

  3. 存储桶名称中,为您的存储桶输入DNS符合标准的名称。

    桶名称必须满足以下要求:

    • 在所有 Amazon S3 中是唯一的。

    • 长度必须介于 3 到 63 个字符之间。

    • 不包含大写字符。

    • 以小写字母或数字开头。

    创建存储桶后,便无法再更改其名称。请确保您选择的存储桶名称在 Amazon S3 中所有现有存储桶名称中唯一。有关存储桶命名规则和约定的更多信息,请参阅《Amazon Simple Storage Service 用户指南》中的存储桶约束和限制

    重要

    避免在存储桶名称中包含敏感信息。存储桶名称在指向存储桶URLs中对象的位置中可见。

  4. 区域中,选择您想要存储桶所在的 AWS 区域。

    请选择一个靠近您的区域可最大程度地减少延迟和成本以及满足法规要求。在某一区域存储的对象将一直留在该区域,除非您特意将其转移到其他区域。有关 Amazon S3 AWS 区域的列表,请参阅中的AWS 服务终端节点Amazon Web Services 一般参考

  5. Bucket settings for Block Public Access(阻止公有访问的桶设置)中,请选择要应用于桶的 Block Public Access(阻止公有访问)设置。

    我们建议您将所有设置保持为启用状态,除非您知道您需要为您的使用案例关闭其中一个或多个设置,例如托管公共网站。您为存储桶启用的阻止公有访问设置也将为您在存储桶上创建的所有访问点启用。有关屏蔽公共访问权限的更多信息,请参阅《Amazon Simple Storage Service 用户指南》中的使用 Amazon S3 屏蔽公共访问权限

  6. (可选)如果要启用 S3 对象锁定:

    1. 请选择 Advanced settings (高级设置),然后阅读显示的消息。

      重要

      您只能在创建存储桶时为其启用 S3 对象锁定。如果您为存储桶启用了对象锁定,则以后无法禁用它。启用对象锁定还会启用存储桶的版本控制。为存储桶启用对象锁定后,必须先配置对象锁定设置,然后才能保护存储桶中的任何对象。有关配置对象保护的更多信息,请参阅使用 Amazon S3 控制台配置 S3 对象锁定

    2. 如果要启用对象锁定,请在文本框中输入 enable 并选择 Confirm (确认)

    有关 S3 对象锁定功能的更多信息,请参阅《Amazon Simple Storage Service 用户指南》中的使用 Amazon S3 对象锁定以锁定对象

  7. 选择创建存储桶

使用创建存储桶时,必须创建一个客户端,然后使用该客户端发送创建存储桶的请求。 AWS SDKs作为最佳做法,您应在同一 AWS 区域中创建客户端和桶。如果您在创建客户端或桶时未指定区域,Amazon S3 将使用默认区域美国东部(弗吉尼亚北部)。

要创建用于访问双栈端点的客户端,必须指定。 AWS 区域有关更多信息,请参阅 Amazon S3 双堆栈端点。有关可用区域的列表 AWS 区域,请参阅中的区域和终端节点AWS 一般参考

创建客户端时,区域映射到特定于区域的端点。客户端使用此端点与 Amazon S3 进行通信:s3.<region>.amazonaws.com。如果您的区域是在 2019 年 3 月 20 日之后启动的,则您的客户端和存储桶必须位于同一区域。不过,您可以使用美国东部(弗吉尼亚北部)区域中的客户端在 2019 年 3 月 20 日之前启动的任何区域中创建存储桶。有关更多信息,请参阅传统端点

这些 AWS SDK代码示例执行以下任务:

  • 通过明确指定 AWS 区域创建客户端 – 在本示例中,客户端使用 s3.us-west-2.amazonaws.com 终端节点与 Amazon S3 通信。您可以指定任意 AWS 区域。有关列表 AWS 区域,请参阅《AWS 一般参考》中的区域和终端节点

  • 通过仅指定桶名称来发送创建桶请求 — 客户端向 Amazon S3 发送请求,请求在您创建客户端的区域中创建桶。

  • 检索有关桶位置的信息 — Amazon S3 将桶位置信息存储在与桶关联的位置子资源中。

创建一个启用对象锁定的存储桶。

示例 1:创建存储桶

以下 create-bucket 示例创建一个名为 my-bucket 的存储桶:

aws s3api create-bucket \ --bucket my-bucket \ --region us-east-1

输出:

{ "Location": "/my-bucket" }

有关更多信息,请参阅《Amazon S3 用户指南》中的创建存储桶

示例 2:创建带有强制拥有者的存储桶

以下 create-bucket 示例创建一个名为 my-bucket 的存储桶,该存储桶对于 S3 对象所有权使用强制存储桶拥有者设置。

aws s3api create-bucket \ --bucket my-bucket \ --region us-east-1 \ --object-ownership BucketOwnerEnforced

输出:

{ "Location": "/my-bucket" }

有关更多信息,请参阅 Amazon S3 用户指南ACLs中的控制对象所有权和禁用

示例 3:在“us-east-1”区域之外创建存储桶

以下 create-bucket 示例在 eu-west-1 区域中创建名为 my-bucket 的存储桶。us-east-1 之外的区域需要指定相应的 LocationConstraint 才能在所需区域创建存储桶。

aws s3api create-bucket \ --bucket my-bucket \ --region eu-west-1 \ --create-bucket-configuration LocationConstraint=eu-west-1

输出:

{ "Location": "http://my-bucket.s3.amazonaws.com/" }

第 2 步:创建 Amazon SNS 主题

如果您的账户中已有 Amazon SNS 主题并想使用该主题,请跳过此步骤并转至步骤 3:创建IAM角色

创建 Amazon SNS 主题
  1. https://console.aws.amazon.com/sns/v3/ hom SNS e 上打开亚马逊主机。

  2. 请执行以下操作之一:

    • 如果 AWS 账户 之前未在您下创建过任何主题,请阅读主页SNS上的 Amazon 描述。

    • 如果 AWS 账户 之前已在您的下方创建过主题,请在导航面板上选择主题

  3. Topics(主页)页面上,选择 Create topic(创建主题)。

  4. Create topic(创建主题)页面上,在 Details(详细信息)部分中,执行以下操作:

    1. 在 “类型” 中,选择主题类型(标准FIFO)。

    2. 输入主题的名称。对于FIFO主题,请在名称末尾添加 .fifo

    3. (可选)输入主题的显示名称

    4. (可选)对于FIFO主题,您可以选择基于内容的消息重复数据删除来启用默认的消息重复数据删除。有关更多信息,请参阅FIFO主题的消息重复数据删除。

  5. (可选)展开加密部分并执行以下操作。有关更多信息,请参阅静态加密

    1. 选择 Enable encryption(启用加密)

    2. 指定客户主密钥 (CMK)。有关更多信息,请参阅关键术语

      对于每CMK种类型,都会显示描述账户CMKARN和。

      重要

      如果您不是的所有者CMK,或者您使用不具有kms:ListAliaseskms:DescribeKey权限的账户登录,则将无法在 Amazon SNS 控制台CMK上查看相关信息。

      要求的所有者授CMK予您这些权限。有关更多信息,请参阅《AWS Key Management Service 开发者指南》中的 “AWS KMS API权限:操作和资源参考”。

      • 默认选择亚马逊 AWS 托管 CMKSNS(默认)别名/aws/sns

        注意

        记住以下内容:

        • 首次使用CMK为主题指定亚马逊 AWS 托管时, AWS KMS 会创建SNSCMK适用于亚马逊的 AWS 托管SNS。 AWS Management Console

        • 或者,在您首次对SSE启用状态的主题使用Publish操作时, AWS KMS 会创建CMK适用于 Amazon 的 AWS 托管SNS。

      • 要使用您的自定义CMK密钥 AWS 账户,请选择客户主密钥 (CMK) 字段,然后CMK从列表中选择自定义密钥。

        注意

        有关创建自定义密钥的说明CMKs,请参阅《AWS Key Management Service 开发者指南》中的创建密钥

      • 要使用CMKARN来自您 AWS 账户 或其他 AWS 账户的自定义密钥,请将其输入到客户主密钥 (CMK) 字段。

注意

您也可以在其他账户中使用 Amazon SNS 主题,但在这种情况下,您可能需要为授予访问权限的主题创建策略 AWS Config。有关向 Amazon SNS 主题授予权限的信息,请参阅,Amazon SNS 主题的权限然后转至步骤 3:创建IAM角色

步骤 3:创建IAM角色

您可以使用IAM控制台创建一个IAM角色,该角色授予访问您的 Amazon S3 存储桶、访问您的 Amazon SNS 主题以及获取支持 AWS 资源的配置详细信息的 AWS Config 权限。当您使用控制台创建IAM角色时, AWS Config 会自动为您附加该角色所需的权限。

注意

如果您使用的是使用的 AWS 服务 AWS Config (例如 Sec AWS urity Hub 或 Cont AWS rol Tower),并且已经创建了IAM角色,则应确保在设置时使用的角色与已创建的 AWS Config 角色 AWS Config 保持相同的最低权限,以便其他 AWS 服务继续按预期运行。 AWS Config

例如,如果 Cont AWS rol Tower 的IAM角色 AWS Config 允许读取 Amazon S3 对象,则应保证在设置时使用的IAM角色中授予的权限相同 AWS Config。否则,它可能会干扰 AWS 控制塔的运行。

有关IAM角色的更多信息 AWS Config,请参阅 Ident AWS ity and Access Managem ent。

为 AWS 服务创建角色
  1. 登录 AWS Management Console 并打开IAM控制台,网址为https://console.aws.amazon.com/iam/

  2. 在IAM控制台的导航窗格中,选择角色,然后选择创建角色

  3. 对于选择可信实体,选择 AWS 服务

  4. 选择你想要的用例 AWS Config:Config-可自定义、Config-OrganizationsCon fig 或 Config-Conformance Packs。然后选择下一步

  5. 命名、查看和创建页面上,查看有关您的角色的详细信息,然后选择创建角色

要使用 AWS SDK,必须使用您的凭据对其进行配置。有关更多信息,请参阅工具参考指南中的共享配置AWS SDKs和凭据文件
