如何在aws-cli ec2命令中使用通配符? [英] How can I use wildcards in `aws-cli ec2` commands?

问题描述

我有一些EC2实例.我想使用 ec2 describe-instances 命令获取基于标签的特定值的实例列表.

I have some EC2 instances. I want to use the ec2 describe-instances command to get a list of instances based on a specific value of a tag.

该表显示了我的用例.

Instance  | Value (key:Purpose)     | Outcome
----------+-------------------------+------------
InstanceA | Going                   | Filter
InstanceB | Shopping,Going          | Filter
InstanceC | Going,Shoping           | Filter
InstanceD | Shopping,Going,Chatting | Filter
InstanceE | GoingGreat              | DONT Filter
InstanceF | NotGoing                | DONT Filter

所以我想以某种方式在ec2-describe-instances命令中使用通配符，以便获得预期的结果.

So I want to somehow use wildcard in the ec2-describe-instances command so that I get the expected outcome.

推荐答案

下面是一个示例，该示例如何根据标记的值过滤 ec2-describe-instances 的输出:

Here is an example of how to filter the output of ec2-describe-instances based on the value of a tag:

aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId]' --filters "Name=platform,Values=windows" --output text

此示例显示所有EC2实例的实例ID，其中"platform"标签设置为"windows".

This example shows the Instance ID for all EC2 instance with the "platform" tag set to a value of "windows".

在Values参数中也可以使用通配符(例如， Name = platform，Values = win * ).

Wildcards are also permitted in the Values parameter (eg Name=platform,Values=win*).
