如何通过EC2的AWS CLI获取所有安全组以显示在表中 [英] How to get all security groups through AWS CLI of an EC2 to show in a table

问题描述

我正在尝试显示所有实例以及附加的安全组，阻止设备名称及其deleteontermination状态.我需要以表格格式显示此数据，但我不断收到以下错误.

I am trying to show all instances along with attached security groups, block device name and their deleteontermination status. I need to show this data in table format but I am continuously getting the below error.

请帮助我了解我在这里缺少什么.

Kindly help me to understand what I am missing here.

PR-MacBook-Pro:~ pr$ aws ec2 describe-instances --output table --query 'Reservations[*].Instances[*].[InstanceId,SecurityGroups[].GroupName,Placement.AvailabilityZone,BlockDeviceMappings[].DeviceName, BlockDeviceMappings[].Ebs.DeleteOnTermination]'

Row should have 1 elements, instead it has 2
PR-MacBook-Pro:~ pr$

推荐答案

我在Google搜索时遇到了这个问题.

I came across this while searching in google.

经过一些研究，我发现您必须使用 |join(`，`，@)

After I did a bit of research I found that you have to use | join(`, `, @)

所以命令将是

aws ec2 describe-instances --output table --query'Reservations [*].Instances [*].[InstanceId，SecurityGroups [].GroupName |join(`，`，@)，Placement.AvailabilityZone，BlockDeviceMappings [].DeviceName |join(`，`，@)，BlockDeviceMappings [].Ebs.DeleteOnTermination |join(`，`，to_array(to_string(@)))]'
