I've just added ElastiCache to my stack, but I'm having problems getting the address from the output using Typescript, has anyone been able to implement this successfully. I'm trying with the same approach I've done for RDS, but keep getting

Calling [toString] on an [Output<T>] is not supported. To get the value of an Output<T> as an Output<string> consider either: 1: o.apply(v => `prefix${v}suffix`) 2: pulumi.interpolate `prefix${v}suffix` See <https://pulumi.io/help/outputs> for more details. This function may throw in a future version of @pulumi/pulumi.

Rather than the expected value

Have you got some example code of what exactly your trying to do?

@echoing-dinner-19531

export async function manageRedisCache(config) {
  try {
    const subnetGroup = new aws.elasticache.SubnetGroup(config.name, {
      name: config.name,
      subnetIds: config.subnetIds,
      description: `Subnet group for ${config.name} Cache Cluster`,
      tags: {
        Name: config.name,
      },
    });
    const redisInstance = await new aws.elasticache.Cluster(config.name, {
      engine: "redis",
      nodeType: config.size,
      numCacheNodes: 1,
      subnetGroupName: subnetGroup.name,
      securityGroupIds: config.securityGroupIds,
      securityGroupNames: config.securityGroupNames,
      tags: {
        Name: config.name,
      },
    });
    return {
      instance: redisInstance,
      data: {
        address: redisInstance.clusterAddress.apply((v) => v),
        port: redisInstance.port.apply((v) => v) as unknown as string,
      },
    };
  } catch (e) {
    throw e;
  }
}

I'm then passing the value from the function into a function to create my Fargate services

Ah right, yes once values are "Outputs" they need to stay Outputs. There is no way to go from

Output<string>

to just

string

except via resources (and they will just return more outputs)

The instance is being created fine, I'm having a problem reading the values for the output

Change your "data.address" and "data.port" to be

Output<string>

@abundant-window-12532 redis elasticache instances don't return a

clusterAddress

, only memcached based ones. You need

redisInstance.cacheNodes[0].address

which is an array You don't need to do an

apply

if you're just returning an

Output

@billowy-army-68599 thanks for that, helped. I'm also seeing vpc under awsx, which has much more functionality that in aws
