AWS CLI S3 A client error (403) occurred when calling the HeadObject operation: Forbidden

Question

I\'m trying to setup a Amazon Linux AMI(ami-f0091d91) and have a script that runs a copy command to copy from a S3 bucket.

 aws --debug s3 cp s3://aws-codede         


        

Answer 1

I had a lambda function doing the same, copy from bucket to bucket.

The lambda had permissions to use the source bucket as trigger.

Configuration tab

But it also needs permissions to OPERATE with buckets.

Permissions tab

If s3 is not there, then you need to edit the Role used by the lambda and add it (see the s3FullAccess)
