如何使用命令行检查 aws ec2 实例创建日期？

Question

To determine how old the aws ec2 instances are, and to destroy those nodes if they are older than 90 days, I need to check the creation date of the node.

What is the correct way to do that using COMMAND LINE?

What I tried?

I tried the command ec2metadata , but the output doesn't contain creation date.

You can get this information with

aws configservice get-resource-config-history --resource-type AWS::EC2::Instance --resource-id i-xxxxxxxx   

The last element in this json is what you need.
You can check get-resource-config-history and find resources between specific dates.
You can also get creation date of your root volume with

aws ec2 describe-volumes --volume-ids vol-xxxxx    

This can also give you age of your root volume (if not changed).
