API requests hang indefinitely

Hi,

I’m using google datastore API and if I run my application from my local computer then the application connects to the datastore, but if I deploy the application it cannot connect to the datastore.

Environment details

• OS: Debian GNU/Linux 8
• Node.js version: 6.9.4
• npm version: shipped with Node.js 6.9.4
• @google-cloud/datastore: 0.6.1

Steps to reproduce

I ran the following example on AppEngine instance:

const Datastore = require('@google-cloud/datastore');

const datastore = Datastore({
      projectId: '<$projectId>',
      keyFilename: './gcloud-keyfile.json'
});

const query = datastore.createQuery('UserModel')
  .filter('user_name', '=', 'gosho');

datastore.runQuery(query)
  .then((results) => {
    const users = results[0];
    users.forEach((user) => console.log(user));
  });

My question is, why cannot my deployed application connect to the datastore?

Thanks!

Just released google-cloud version 0.46.2 – anyone willing to test, please update and let us know how it went.

We suspect that this is due to a recent change in grpc@1.1.1 not dealing properly with the lack of /etc/services. We are working on an updated version of the Node.js docker image with a work-around that should be available in a few hours.

Could folks try deploying again (in a few hours) with the latest runtime image to see if the problem gets resolved?
