Unable to login to ECR

Hello. I am having issues logging in to ecr using docker-py, my code is as follows:

from docker import Client
client = Client(base_url = 'tcp://127.0.0.1:2375')
client.login(username='AWS', password=auth_code, registry='https://xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com')
client.pull('xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/foo:latest')

Results with the following error:

docker.errors.APIError: 500 Server Error: Internal Server Error ("error parsing HTTP 403 response body: invalid character 'Y' looking for beginning of value: "Your Authorization Token has expired. Please run 'aws ecr get-login' to fetch a new one."")

The thing is, auth_code is generated from aws ecr get-login, which works perfectly. Can any one shed some light on this?

I did some debugging and in docker/api/image.py response is status_code 500 text:

error parsing HTTP 403 response body: invalid character 'Y' looking for beginning of value: "Your Authorization Token has expired. Please run 'aws ecr get-login' to fetch a new one."

I found it helpful to delete the Amazon login credentials from ~/.docker/config.json as well. The token is only good for 12 hours.

It looks like somewhere in the login process the local version is finding what it thinks is an auth and so the login uses the cached result. Adding reauth=True to the login call fixes it. Sorry for the rabbit hole Tomas.
