#PubSub -> Cloud Storage Function

As the name suggests, this function can be used to subscribe to a pub/sub, create files and write them to cloud storage.

Files are created in a bucket in profile_id/filename format.

Create a pubsub topic if it doesnt already exist using:

 gcloud beta pubsub topics create YOUR_TOPIC_NAME

Create a bucket to stage the deployments of the function:

 gsutil mb gs://YOUR_BUCKET_NAME

Deploy the subscribe function using:

 gcloud alpha functions deploy subscribe --stage-bucket YOUR_BUCKET_NAME --trigger-topic YOUR_TOPIC_NAME

This will ensure that all files being written into Pub/Sub will be consumed by the function and written into Cloud Storage.
