如何创建只能访问特定S3存储桶的访问密钥

Question

I have four S3 buckets bucket1, bucket2, bucket3, bucket4 . I would like to create a new Access/secret key that only has access to these four buckets.

How should I do this? Should I use IAM to create a new user, then login as that user, and create the S3 buckets? Would I need to create a new policy?

Answer 1

Create an IAM policy that only gives access to these four buckets. You do this by specifying the ARN of each bucket in the policy. Create an IAM user and assign the policy to that user. Create access keys for that user.

Here is some documentation on creating the IAM policy to grant access to specific S3 buckets.
