that is, if it detects that it already exists, use it, otherwise create it.

That's what should be happening the bucket should only be created the first time

in myStack im doing this

As long as the bucket_name stays the same it shouldn't create a new bucket every time

@thdxr only if it was created in that same app the first time around. Right?

Well if the bucket name is the same it should fail to create

Exactly.
