Sample app:

import * as gcp from '@pulumi/gcp';

// Create a GCP resource (Storage Bucket)
export const bucket = new gcp.storage.Bucket('testBucket', {
  name: 'mytestbucketforjson',
  project: 'mindbody-casey-robertson'
});

new gcp.storage.BucketIAMMember(
  'my-bucket-iam',
  {
    bucket: bucket.name,
    member: 'allUsers',
    role: 'roles/storage.objectViewer'
  },
  {
    // Track Pulumi component by attaching to parent.
    // https://pulumi.io/reference/programming-model.html#components
    parent: bucket
  }
);

// Export the DNS name of the bucket
export const bucketName = bucket.url;
