Docker build fails during Meteor install on Windows with the following output:

... Installing Meteor 1.8.0.2

Downloading Meteor distribution
Retrying download in 5 seconds...
Retrying download in 5 seconds...
*repeat last line*

After diving into the container I figured out that the culprit is this line in install-meteor.sh:
METEOR_VERSION=$(head $APP_SOURCE_DIR/.meteor/release | cut -d "@" -f 2)

On Windows the line endings are \r\n. This means that cut outputs 1.8.0.2\r in METEOR_VERSION. Since this version doesn't exist, the Meteor install script keeps 404'ing and retrying.
