Boto3 get Elasticache ARN

Question

I am trying to automate the creation and destruction of services in AWS. the destruction is tag-based, in order to use boto3.client('elasticache').list_tags_for_resource() I need to supply its ARN of the cache-cluster and it's not part of the describing method boto3.client('elasticache').describe_cache_clusters() like in other resources (DynamoDB or RDS for example) is there a different way to get the ARN (except of assembling it manually) or an alternate way to iterate over the existing cache-clusters and check the tags?

Answer 1

Based on AWS document , You can generate ARN with a format below.

arn:aws:elasticache:region:account-id:cluster:resource-name

Example:

arn:aws:elasticache:us-west-2:0123456789:cluster:myCluster

or

arn:aws:elasticache:us-west-2:0123456789:snapshot:mySnapshot
