Elasticache Redis clustered mode

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"
