How to add IAM role to an existing instance in aws

Question

I would like to add an IAM Role to an existing EC2 instance in AWS. I tried using AWS CLI, however I could not find a way to do that.

Answer 1

As of AWS CLI v1.11.46,  you can now attach an IAM role to an existing EC2 instance that was originally launched without an IAM role using the associate-iam-instance-profile command.

You can also replace the currently attached IAM role for a running instance using replace-iam-instance-profile-association.
