有没有办法列出通过aws-cli按CreatedTime排序的启动配置？

Question

I am finding a way on how to list launch configurations sorted by CreatedTime . When I ran this command below, it does not return the oldest LC:

aws autoscaling describe-launch-configurations --max-items 1

Is there a way for this? Thank you!

You can control the the command's output using a JMESPath expression like this:

aws autoscaling describe-launch-configurations --query 'reverse(sort_by(LaunchConfigurations, &CreatedTime))'

The previous command will list all launch configurations ordered by descending CreatedTime . If you only want to get the latest launch config based on CreatedTime , add the [0] expression at the end of the command:

aws autoscaling describe-launch-configurations --query 'reverse(sort_by(LaunchConfigurations, &CreatedTime))[0]'
