Hi,

I’m trying to spin up a clustered mode of redis instance and it seems like this results in ansible trying to spin up a non clustered mode of redis. There is no parameter for clustered mode, so only way for signifying cluster seems to be setting cluster.on in parameter group. Below is my yml

> - name: Provision cluster redis aws  
> hosts: localhost  
> connection: local  
> tasks:
> - name: Set up redis cluster  
> elasticache:  
> name: “clustered-redis”  
> state: present  
> engine: redis  
> region: “us-east-1”  
> cache\_engine\_version: 3.2.10  
> node\_type: cache.t2.small  
> num\_nodes: 1  
> cache\_port: “6379”  
> cache\_parameter\_group: “default.redis3.2.cluster.on”

Below is the error I get back from running above, (aws access keys set as env variable)

> “msg”: “An error occurred (InvalidParameterCombination) when calling the CreateCacheCluster operation: Cluster mode should be disabled in parameter group, but found it is enabled.”,

Is there support for a clustered mode of redis on AWS Elasticache?

I could not find a module for elasticache where cluster on,  
however, I used the command module to create the elasticache,

aws elasticache create-replication-group --replication-group-id xxxx --cache-parameter-group-name “default.redis7.1.cluster.on”

creating a replication group can use the default.redis7.1.cluster.on"
