如何检测EBS卷类型？

Question

Is it possible to detect if an attached EBS volume is using GP2 (SSD) or provisioned IOPS (io2)?

Is there a simple curl command I can issue to detect what is attached to my instance? I am on the instance that I want to run this command on.

I'd also like to do it without requiring the AWS credentials

There is no curl command that will let you know what is the volume type. You will either have check that through the console. Or another way is using a AWS CLI command. Also that is not possible without using AWS Credentials .

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-describing-volumes.html

Using CLI Command.

aws ec2 describe-volumes
