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 figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared
