Retrieve project id from Google Compute Engine machine?

I have two Google Cloud Platform projects (staging and production). I would like my application deployed on Google Compute Engine instance to automatically detected the project id. What is the way to do it?

In my environment I've got:

curl: (6) Could not resolve host: metadata.google.internal

The following worked for me:

PROJECTID=`gcloud projects list | awk 'FNR>1 {print$1}'`

which returns the project details, which is then parsed for project id.

You can determine project ID directly in shell script with: 

PROJECTID=$(curl -s "http://metadata.google.internal/computeMetadata/v1/project/project-id" -H "Metadata-Flavor: Google")

Or use metadata lib for your language to get required data.
I'm able to get project ID in Golang with: 

import "cloud.google.com/go/compute/metadata"
...
var ProjectId, _ = metadata.ProjectID()

You can query the metadata server programmatically for a variety of information, including the project id.

For the project id:

$ curl "http://metadata.google.internal/computeMetadata/v1/project/project-id" -H "Metadata-Flavor: Google"

This will return your project id, eg: my-gcp-project

Or if you need the numeric project id:

$ curl "http://metadata.google.internal/computeMetadata/v1/project/numeric-project-id" -H "Metadata-Flavor: Google"

This will return the numeric project id, eg: 0123456789
