IAM policy on S3 bucket

Question

I always get confused in two but I wanted to add a IAM policy on S3 bucket. Basically I have created an output bucket for Amazon transcriptions but it seems I need to add IAM role to allow Transcription job to write to the bucket. I think if I can attach AmazonTranscribeFullAccess to S3 bucket, it will work but I am unable to attach this policy. Could you please advise how can I add this policy on the new bucket?

Answer 1

There are a few concepts you will want to dig deeper into to understand the difference between IAM policies and S3 bucket policies. A detailed guide is: https://docs.aws.amazon.com/AmazonS3/latest/dev/how-s3-evaluates-access-control.html

You can attach IAM policies to Users, Groups and Roles, and you can attach bucket policies to S3 buckets.

Try adding S3 access to the user/role that you are using to run the transcribe job.
