title: Envrionment variables in Cloud Run referencing the Google Cloud project id
body: <p>Even though it was not documented <a href="https://cloud.google.com/run/docs/reference/container-contract#env-vars" rel="nofollow noreferrer">here</a>, I think the <code>GOOGLE_CLOUD_PROJECT</code> environment variable used to be defined inside the container but it is not anymore  </p>
  
  <p>I can even find it referenced in code here:<br>
  <a href="https://github.com/kelseyhightower/konfig/blob/master/konfig.go#L314" rel="nofollow noreferrer"><code>project := os.Getenv("GOOGLE_CLOUD_PROJECT")</code></a></p>
  
  <p>Where can I find my project id?</p>
