Granting Access to an S3 Bucket for a User
Below you can find a step-by-step guide on how to set access to a specific Amazon S3 bucket for a single user (a bucket user-lionin the example):
- Go to My Security Credentials.
- Select Get Started with IAM Users.
- Select the Create Policy option in the Policy section, then select Create Your Own Policy.
- The next step is to add a Policy Document, which will look like this:
*This Policy does not require editing. I.e. you permit to use the methods “s3:ListBucket” and “s3:GetBucketLocation” with the bucket
arn:aws:s3:::${aws:username}, and “s3:PutObject”, “s3:GetObject”, “s3:DeleteObject”, “s3:PutObjectAcl” for the all objects in that bucket.
- At this step, you will need to go back to My Security Credentials, select the Users section and create a user who will have access to the mentioned bucket.
- Then, attach the previously created policy to a user.
