Cannot run python cal sample from container (auth fails)

[drewkhoury]

Expected Behavior

When I try to run the python cal sample from within a container it should allow me to auth successfully.

Actual Behavior

The terminal (in container) provides an "offline url" which when clicked (on desktop) redirects to a random high port that is not available from the desktop.

e.g:
Clicking "Allow" will redirect you to: http://localhost:46603
Clicking "Allow" will redirect you to: http://localhost:40391

Steps to Reproduce the Problem

1. docker run -it python bash
2. container> pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
3. container> python quickstart.py
4. host (chrome)> Please visit this URL to authorize this application: https://accounts.google.com/o/oauth2/auth?...&access_type=offline
5. Auth, then the redirect will fail

Note: Have also tried modifying the auth code to run on port 8080 and expose that port in the container. Have also confirmed that the port is exposed with a test of "python -m http.server 8080" in the container.

The quickstart isn't written to be run in a container, and from some experimentation, there are some challenges depending on which host OS is used. A linux host with --net=host -p 8080:8080 + modify code to set port to 8080 should work, but may fail on a mac or others due to the server binding to localhost (instead of all addresses.)

Easiest way to get it to run on a container is to change the flow -- change run_local_server to run_console. Requires copy/pasting the resulting auth code, but simple if you just need to get it to work and try things out.
