How to utilize temporary AWS credentials in a launched EC2 instance, I can't seem to get an extremely simple POC running.
- Launch an EC2 instance
- SSH in
- Pull a piece of static content from a private S3 bucket
- Create an IAM role
- Spin up a new EC2 instance with the above IAM role specified; SSH in
- Set the credentials using aws configure and the details that (successfully) populated in http://169.254.169.254/latest/meta-data/iam/security-credentials/iam-role-name
- Attempt to use the AWS CLI directly to access the file
When I use the AWS CLI to access the file, this error is thrown:
A client error (Forbidden) occurred when calling the HeadObject operation: Forbidden
Completed 1 part(s) with ... file(s) remaining
Which step did I miss?
