Docker -it on Windows 10 bash, input device is not a TTY

I'm having issues running Docker containers interactively on Windows using bash.
Here's the output when I run my sup command:
```
2019/06/14 12:57:01 Running task docker run -it --env-file=.env $NAME ./test.py
the input device is not a TTY.  If you are using mintty, try prefixing the command with 'winpty'
exit status 1

```
