amazon-web-services - 您没有启用 Auto Scaling 所需的角色

Question

我在尝试创建表时看到此警报。我已按照 these instructions 将 AmazonDynamoDBFullAccess 策略添加到我的 IAM 用户。

我已经退出/登录，但仍然收到此消息。我需要额外的策略才能在 DynamoDB 中启用自动扩展吗？

我不知道你是否已经找到了这个问题的答案，但你要做的就是进入“IAM”中的“角色”并创建一个新角色。您选择“Application Auto Scaling”，然后选择“Application Auto Scaling -DynamoDB”，再单击“下一步”几次，即可完成。当前文档似乎并未涵盖此步骤。
