If I have an array of AZ names created like this:

azNames := make([]string, numOfAZs)
for idx := 0; idx < numOfAZs; idx++ {
	azNames[idx] = rawAzInfo.Names[idx]
}

where

rawAzInfo

is the result of the

aws.GetAvailabilityZones

resource, how can I use that array as an input to the AvailabilityZones argument of the

elb.NewLoadBalancer

resource? Alternately, if I have an array of instance IDs, how could I use that array of instance IDs as an input to the Instances argument of the

elb.NewLoadBalancer

resource?

AvailabilityZones

is of type

pulumi.StringArrayInput

so we would need to construct a

pulumi.StringArray

. https://github.com/pulumi/pulumi-aws/blob/master/sdk/go/aws/elb/loadBalancer.go#L264 Should be something like:

azNames := make([]pulumi.StringInput, numOfAZs)
for idx := 0; idx < numOfAZs; idx++ {
	azNames[idx] = pulumi.String(rawAzInfo.Names[idx])
}

OK, thanks for that. I've made the change, but I'm not quite sure how to reference it in the ELB configuration. Is this right...?

elb, err := elb.NewLoadBalancer(ctx, fmt.Sprintf("elb-%s", baseName), &elb.LoadBalancerArgs{
	AvailabilityZones: pulumi.StringArray{azNames},
	Instances:         pulumi.StringArray{cpNodeIds},
})

I would expect that you should be able to just reference aznames directly

AvailabilityZones: azNames,

given that

pulumi.StringArrayInput

is just a type alias for

[]pulumi.StringInput

That was my thought, too, but

gopls

gives me this: "cannot use azNames (variable of type []pulumi.StringInput) as pulumi.StringArrayInput value in struct literal: missing method ElementType"

What if you wrap it in

pulumi.StringArray(azNames)

That seems to work. I swear I thought I'd tried that already, but 🤷🏻‍♂️
