AWS CLI查找活动的预留实例列表 [英] AWS CLI to find out list of active reserved instances

问题描述

我正在尝试找出活动的保留实例的列表.

I am trying to find out list of reserved instances that are active.

aws ec2 describe-reserved-instances --filters  "Name=instance-state-State,Values=active" --query 'Reservations[].Instances[].Tags[?Key==`Name`].Value[]'

上面的命令不起作用，我认为Name字段不正确. 有什么帮助吗? 谢谢

The above command does not work, and I think the Name field is not right. Any help? Thanks

推荐答案

这是另一种说法.搜索

State == `active`

进入查询语句.输出也包括标签.顺便说一句，从查询周围的单引号更改为双引号(在Mac上)，将需要您使用反斜杠转义反引号.

into the query statement. The output includes labels as well. By the way, changing from single-quotes around the query to double-quotes (on a mac) will require you to escape the backticks with backslashes.

aws ec2 describe-reserved-instances --query 'ReservedInstances[?State == `active`].{Count: InstanceCount, Type: InstanceType}' --output json

输出:

[
    {
        "Count": 50,
        "Type": "t2.medium"
    },
    {
        "Count": 3,
        "Type": "m4.2xlarge"
    },
    {
        "Count": 17,
        "Type": "m3.large"
    },
    {
        "Count": 3,
        "Type": "m3.2xlarge"
    },
    {
        "Count": 2,
        "Type": "m3.2xlarge"
    },
    {
        "Count": 3,
        "Type": "m3.xlarge"
    },
    {
        "Count": 6,
        "Type": "m4.4xlarge"
    }
]
