Which role is attached to instance

Question

How to check which IAM roles and it's policy json, are attached to the running EC2 instance?

Is it possible through AWS CLI?

I tried firing the command - aws iam list-instance-profiles,
it gave me the following error -

An error occurred (AccessDenied) when calling the ListInstanceProfiles operation: User: is not authorized to perform: iam:ListInstanceProfiles on resource:

No need to look for AWS CLI installed your Machine, Just machine should have internet and no block from metadata. You can curl the metadata from EC2:

curl -s http://169.254.169.254/latest/meta-data/iam/info |grep InstanceProfileArn  | awk '{print $3}'
