How can I find the endpoint after I have created a Redis instance using the CDK?

Question

I'm doing this to create a Redis instance:

```
redis_cache_cluster = aws_elasticache.CfnCacheCluster(
            self,
            "RedisCacheCluster",
            cluster_name=f"ctest",
            cache_node_type="cache.t2.micro",
            cache_subnet_group_name="ghjghj",
            engine="redis",
            engine_version="7.0",
            num_cache_nodes=1,
            port=6379,
            vpc_security_group_ids=[
                'ghjghj'
            ]
        )
```

How can I get the endpoint after this? (Then assign it to an environment variable for a lambda?)

Mick, based on the documentation [here](https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_elasticache/CfnCacheCluster.html), it looks you should be able to use the following properties from the ```redis_cache_cluster``` variable to get the endpoint information:
* [attr_configuration_endpoint_address](https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_elasticache/CfnCacheCluster.html#aws_cdk.aws_elasticache.CfnCacheCluster.attr_configuration_endpoint_address)
* [attr_configuration_endpoint_port](https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_elasticache/CfnCacheCluster.html#aws_cdk.aws_elasticache.CfnCacheCluster.attr_configuration_endpoint_port)
* [attr_redis_endpoint_address](https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_elasticache/CfnCacheCluster.html#aws_cdk.aws_elasticache.CfnCacheCluster.attr_redis_endpoint_address)
* [attr_redis_endpoint_port](https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_elasticache/CfnCacheCluster.html#aws_cdk.aws_elasticache.CfnCacheCluster.attr_redis_endpoint_port)

I hope this helps.

Hi Mick.

There are several ways to find the endpoints. Please see the following [documentation page](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Endpoints.html) and use your preferred method (Console, CLI, or API).

I hope this helps.

I managed to get this working using CodeWhisperer:

```
redis_endpoint = redis_cache_cluster.attr_redis_endpoint_address
```
