Also, confusingly, the docs:
Copy code
CacheNodes
[]ClusterCacheNode
List of node objects including id, address, port and availability_zone. Referenceable e.g. as ${aws_elasticache_cluster.bar.cache_nodes.0.address}
appear to suggest referencing via terraform syntax? lol.
Probably has a lot to do with me being in over my head with Go, admittedly.

@ambitious-salesmen-39356 it's not iterable because it's an output, if you wrap it in an Apple func you can iterate with it. What are you trying to do exactly?
a
Just get any and all DNS addresses out of the cluster. Memcached exposes it as a top level output, redis doesn't
b
are you trying to pass them to another resource?
a
yeah a route53 record and probably as a stack export as well.
b
can you share the code you have?
a
Well, what I was trying to do is not viable apparently =D
b
ha! maybe some pseudo code for wyat you're trying to do?
a
if this was python...
Copy code
deployment.clusterDNS = cluster.CacheNodes[0].address
it's a single node cluster, I'd have to range loop it for a multi-node naturally
I have no formal developer/CS background so I probably struggle more with this sort of thing than most.
b
me neither, we can struggle through this together 🙂 give me a little while I'll try some stuff out
a
You really have been exceptionally helpful. Sadly I sent in the registration forms for my firstborn many years ago, so I'll have to find something else to name in your honour

b
can you share your memcache code @ambitious-salesmen-39356? I'm gonna try figure this out now
a
redis actually, or this would be easy 🙂
@billowy-army-68599 I actually figured it out: https://www.pulumi.com/docs/intro/concepts/programming-model/#lifting 
deployment.clusterDNS *=* cluster.CacheNodes.Index(<http://pulumi.Int|pulumi.Int>(0)).Address().Elem()
b
oh wow, I was just fighting this!
I was using the index and the nodes as well, I'll post my solution in a bit but I'd love to see yours too
a
I mean, that's it really
Copy code
r53RecordName := pulumi.String(fmt.Sprintf("<http://redis.%s.veem.com|redis.%s.veem.com>", pulumi.String(ev.Get("name"))))

	_, err = route53.NewRecord(ctx, clusterName, &route53.RecordArgs{
		Name:   r53RecordName,
		Ttl:    <http://pulumi.Int|pulumi.Int>(300),
		Type:   pulumi.String("CNAME"),
		ZoneId: pulumi.String("<REDACTED>"),
		Records: pulumi.StringArray{
			cluster.CacheNodes.Index(<http://pulumi.Int|pulumi.Int>(0)).Address().Elem(),
		},
	}, pulumi.Parent(deployment))
b
love it!
a
I just pulled it from the programming model docs and prayed ¯\_(ツ)_/¯
