AWSR001

The AWSR001 analyzer reports when a fmt.Sprintf() call contains the format string ending .amazonaws.com. This domain suffix is only valid in the AWS Commercial and GovCloud (US) partitions.

To ensure the correct domain suffix is used in all partitions, the *AWSClient available to all resources provides the PartitionHostname() and RegionalHostname() receiver methods.

Flagged Code

fmt.Sprintf("%s.amazonaws.com", d.Id())

fmt.Sprintf("%s.%s.amazonaws.com", d.Id(), meta.(*AWSClient).region)

Passing Code

meta.(*AWSClient).PartitionHostname(d.Id())

meta.(*AWSClient).RegionalHostname(d.Id())

Ignoring Check

The check can be ignored for a certain line via a //lintignore:AWSR001 comment on the previous line or at the end of the offending line, e.g.

//lintignore:AWSR001
fmt.Sprintf("%s.amazonaws.com", d.Id())
