Use AWS CLI and JQ to get a list of instances sorted by launch time

Use the AWS CLI tools to generate a list instances, then pipe them to JQ to show only their launch time and instance id. Finally use sort to bring them out in runtime order. Find all those instances you launched months ago and have forgotten about.


There is 1 alternative - vote for the best!

Terminal - Alternatives
aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId,LaunchTime]' --output text | sort -n -k 2

You can do the filtering natively in the aws cli, without using jq (although jq is awesome!)

Know a better way?

If you can do better, submit your command here.

What others think

How would you go about listing instances in certain VPC with the Tag Name, private IP address of instance and instance id? The closest I have get is using the following commands.

This manage to lists all name of instances.

aws ec2 describe-instances --filters Name=vpc-id,Values=vpc-e2f17e8b --query 'Reservations[].Instances[].Tags[?Key==`Name`].Value[]'

This manage to list all private ip address, instance id and ALL tags which I don't need. I just need the name.

aws ec2 describe-instances --filters Name=vpc-id,Values=vpc-e2f17e8b | jq '.Reservations[].Instances[] | {PrivateIpAddress, InstanceId, Tags}'

I'm not sure why I can't execute command like yours in this way:

aws ec2 describe-instances | jq '.["Reservations"]|.[]|.Instances|.[]|.PrivateIpAddress + " " + .InstanceId + " " + .Tags[?Key==`Name`].Value[]'

This works but its showing all the Tags Key names

aws ec2 describe-instances | jq '.["Reservations"]|.[]|.Instances|.[]|.PrivateIpAddress + " " + .InstanceId + " " + .Tags'
