通過CLI停止RDS實例

Question

我正在嘗試使用AWS的最新功能之一，它允許您停止RDS實例。

我跟着this doc它解釋說，我需要運行命令：但是 aws rds stop-db-instance --db-instance-identifier mydbinstance，當我這樣做，我得到這個：

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 

並繼續列出其他RDS命令，但不包括stop-db-instance。 我更新了我的CLI和我擁有的當前版本：aws-cli/1.11.11 Python/2.7.9 Windows/8 botocore/1.4.68

我錯過了什麼？

UPDATE

我試圖CLI再次升級AWS然而我找回的是，一切是最新的：

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

C:\Users\n.ihab>pip install awscli --upgrade

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

有沒有別的東西，我需要在升級之前到這一步？

Answer 1

這是自CLI版本1.11.95以來的新功能。最新版本是1.11.109。更新至最新的AWS CLI版本，你可以使用stop-db-instance

升級之前

$ 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: 

升級CLI和重新啓動（Linux）的

$ sudo pip install awscli --upgrade 

後升級

$ 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
