Node.js check if running locally or in google cloud VM?

Question

In a Node.js script, How can I check if I'm running in Google Cloud VM or locally?

I'm not using Google App Engine.

Is it possible to do this without making any network requests, synchronously?

The correct method as mention by Kolban is to check the instance metadata. Environment variables are not reliable. — John Hanley

Thanks @Kolban! That's what I was looking for (although would be better to not have to make a network request). — d-_-b

You could, for example, check for the various environment variables that will be set, such as GOOGLE_CLOUD_PROJECT or GAE_INSTANCE, accessible from a Node.js script as:

process.env.GOOGLE_CLOUD_PROJECT

Edit /etc/environment on the VM, append the following:

GCLOUD=1

And then in Node:

const isRunningInVM = Boolean(process.env.GCLOUD)
