If I explicitly set the

name

on a

aws.elasticloadbalancingv2.TargetGroup

then update the

port

to a different value, I get this message:

Plan apply failed: Error creating LB Target Group: DuplicateTargetGroupName: A target group with the same name 'fibonacci-dev' exists, but with different settings
        status code: 400, request id: db1ef58c-fd8f-11e8-be77-fbf35d396053

@stocky-spoon-28903 I assume this is because Port is a force-new property and so we re-create the resource before trying to delete the old version.

That seems to defeat the purpose of using a

name

, no?

It appears that the AWS API requires

name

to be unique across a region. I guess the

name_prefix

property is exposed by terraform (and projected by pulumi as

namePrefix

) was added to do the autonaming by default. When name is unset, you just get a resource with the name

tf-<some-random-id>

I think explicitly setting name and then trying to do any operation which requires the resource to be replaced (and it looks like for TargetGroup changing many properties requires the entire resource to be replaced) is not going to work given that we don't set delete before create today. But @stocky-spoon-28903 or @microscopic-florist-22719 would know for certain.
