How do you determine the ARN of a Redshift cluster via the AWS API?

Question

I'm trying to add tags to a Redshift cluster using CreateTags, http://docs.aws.amazon.com/redshift/latest/APIReference/API_CreateTags.html and you'll notice it requires an ARN for the resource.

Is there some other API call to retrieve the ARN or do I have to construct it manually?

The ARN format is documented here. Specifically for a Redshift cluster the ARN format is:

arn:aws:redshift:region:account-id:cluster:cluster-name

If you know the region, account-id and cluster-name then you can construct the ARN.
