通过CLI停止RDS实例

Question

我正在尝试使用AWS的最新功能之一,它允许您停止RDS实例.

我按照这个文档说明了我需要运行命令: aws rds stop-db-instance --db-instance-identifier mydbinstance但是,当我这样做时,我得到了这个:

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:

add-role-to-db-cluster                   | add-source-identifier-to-subscription
add-tags-to-resource                     | apply-pending-maintenance-action

它继续列出其他RDS命令,但不包括stop-db-instance.我更新了我的CLI和我当前的版本:aws-cli/1.11.11 Python/2.7.9 Windows/8 botocore/1.4.68

我错过了什么？

UPDATE

我试图再次升级aws cli,但我得到的回报是一切都是最新的:

C:\Users\n.ihab>aws --version
aws-cli/1.11.11 Python/2.7.9 Windows/8 botocore/1.4.68

在此步骤之前我还需要升级其他东西吗？

这是一个新功能,自CLI版本起可用1.11.95.最新版本是1.11.109.更新到最新的AWS CLI版本,您可以使用stop-db-instance

升级前

$ aws --version
aws-cli/1.11.83 Python/2.7.10 Linux/4.1.17-22.30.amzn1.x86_64 botocore/1.5.46

$ aws rds stop-db-instance    
aws: error: argument operation: Invalid choice, valid choices are:

升级CLI并重启(Linux)

$ sudo pip install awscli --upgrade

升级后

$ aws --version
aws-cli/1.11.109 Python/2.6.9 Linux/4.1.17-22.30.amzn1.x86_64 botocore/1.5.72

$ aws rds stop-db-instance
aws: error: argument --db-instance-identifier is required
