Invoking gsutil or gcloud from a Google cloud function?

I have a Google Firebase app with a Cloud Functions back-end. I'm using the node.js 10 runtime which is Ubuntu 18.04. Users can upload files to Google Cloud Storage, and that triggers a GCF function.

What I'd like that function to do is copy that file to Google Cloud Filestore (that's File with an L), Google's new NFS-mountable file server. They say the usual way to do that is from the command line with gsutil rsync or gcloud compute scp.

My question is: are either or both of those commands available on GCF nodes? Or is there another way? (It would be awesome if I could just mount the Filestore share on the GCF instance, but I'm guessing that's nontrivial.)

Using NFS based storage is not a good idea in this environment. NFS works by providing a mountable file system, something that will not work in Cloud Functions environment as the file system is read only with the exception of /tmp folder.

You should consider using cloud native storage systems like GCS for which the Application Default Credentials are already setup. See the list of supported services here.

According to the official documentation Cloud Filestore documentation

Use Cloud Filestore to create fully managed NFS file servers on Google Cloud Platform (GCP) for use with applications running on Compute Engine virtual machines (VMs) instances or Google Kubernetes Engine clusters.

You can not mount the Filestore on GCF.

Also, you can not execute gsutil or gcloud commands from a Google cloud function Writing Cloud Functions.

Google Cloud Functions can be written in Node.js, Python, and Go, and are executed in language-specific runtimes
