Unable to run clasp in a Docker container.

Expected Behavior

I should be able to run clasp in a docker container.

Actual Behavior

Unable to authenticate as localhost service is listening on a random port.

Steps to Reproduce the Problem

1. docker-compose.yml

version: '2'

services:

  svc_gsuite:
    image: chrisgarrett/node-dev:8.2.1
    command: npm run up
    volumes:
    - ./src:/work/app
    - ~/.clasprc.json:/home/node/.clasprc.json

1. up script entry in package.json:

"up": "yarn install && npx clasp login && npm run watch",

1. copy link in and paste into browser.
2. redirection fails because port is random.

Specifications

• Node version (node -v): 8.2.1
• Version (clasp -v): 1.5.3
• OS (Mac/Linux/Windows): alpine 3.6

Options

1. Use an environment variable to specify port. This feels pretty natural as there are many node examples where this is used. I have this working already in my fork
2. Add an argument to login to specify the port.

Thoughts?

I will submit a PR for either of these after some feedback.

Can you be more specific on how you used clasp?

Can you run:

clasp login --no-localhost

What is the error you see?

See https://github.com/google/clasp#login

The clasp login --no-localhost option is for computers that can’t run local servers. If you want to not login at all, just login once and copy the ~/.clasprc to your machine’s home directory. Let me know if there’s something that you’d like changed, but this case of not using localhost is expected.
