aws.sns.TopicSubscription

is where I started my search, but the problem with it is that

aws.sns.TopicSubscriptionArgs.topic

is required to be of type

pulumi.Input<aws.sns.Topic>

. Right now I am wishing it could be of type

pulumi.Input<aws.sns.Topic | aws.ARN>

i think you could do this by doing aws.sns.Topic.get

to create a pulumi resource instance for an existing aws topic

you can then subscribe to a lambda off of that topic

I'm looking into that as well.

It seems that that first argument,

name

, is arbitrary. The second arg,

id

, would be the ARN. But I'm getting an error:

InvalidParameter: Invalid parameter: TopicArn

. I suspect that I need to provide a custom provider to

aws.sns.Topic.get()

because the topic is in a different region.

that sounds reasonable

First result: Using

aws.sns.Topic.get()

works when the topic is found in the same region as the stack's default.

Final result: It works across regions, as long as an

aws.Provider

representing the foreign region is supplied to both

aws.sns.Topic.get()

and

new aws.sns.TopicSubscription()
