Not sure I understand the question correctly. You can specify your own name, without the auto-generated suffix. <https://www.pulumi.com/docs/intro/concepts/resources/names/#autonaming>

``` this.RTassnA = new aws.ec2.RouteTableAssociation(this.vpc.id + "assnA",{
      subnetId: this.subnet1.id.toString(),
      routeTableId: this.privatertA.id,
    },{parent: this});```

I thought I could append the vpcId to it but Im overriding the values in the name tag.

nvm, generated my own UUID for the resource to stop name collision

ok nvm dont add a uuid to your resource name or itll delete your entire stack...like resources you arent even changing

Wait what? There must be something else going on.

replaced my network and made me have to get our network team to reconnect the tgw to it

here is the stack output from the pipeline

its cool though...it was just our lab. I have the pipeline require manual intervention for our prod environments so I was able to stop it

but yeah it replaced everything after just adding a uuid to a route table name and association

<@U01T6KFAADP> You might find this example code a useful reference for both the infra you're building and the naming stuff you're hitting: <https://github.com/pulumi/workshops/tree/main/aws-advanced-networking>

This is an example of how I get unique names within components: <https://github.com/pulumi/workshops/blob/main/aws-advanced-networking/hub.py#L29-L30>
