I am trying to create ecr repo using pulumi typescript used basic example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const foo = new aws.ecr.Repository("foo", {
    imageScanningConfiguration: {
        scanOnPush: true,
    },
    imageTagMutability: "MUTABLE",
});

but when my repo gets created i am expecting name to be foo but it creates repo with random id foo-719afa7 how to create repo without random id ?
