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.

But when you call DescribeClusters, http://docs.aws.amazon.com/redshift/latest/APIReference/API_DescribeClusters.html no ARN is returned.

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

Sample

Answer 1

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.

Is the implication that you have to assemble this one manually? The other AWS services return fully constructed ARNs for resources. – Sample

The implication is that you can easily construct them manually. – Scutiform

Shouldn't this be displayed in the AWS console when viewing the cluster? I cannot find it. – Weep

@MatthewJamesBriggs Yes, it should be displayed, yet here we are 3 years later and it still doesn't appear to be visible in the AWS Console. – Cineaste

I don't see it in my console! every single resource beside redshift displays an arn. – Wagstaff

So annoying AWS doesn't display the ARN. It's the little things like these that make me doubt the modern IT industry :) – Roorback

Answer 2

The cluster ARN is now displayed within the Management Console's General Information pane (Amazon Redshift -> Clusters -> 'cluster-name'), and includes an identifier for the cluster's namespace:

arn:aws:redshift:region:<account_number>:namespace:<cluster_namespace_id>
