Andrey Devyatkin a67ba5536d Fix #3281: Unexpected result when using build args with default values ... Fix the issue when build arg is set to None instead of empty string. Usecase: cat docker-compose.yml .... args: - http_proxy - https_proxy - no_proxy If http_proxy, https_proxy, no_proxy environment variables are not defined then http_proxy, https_proxy, no_proxy build args will be set to string None which breaks all downloads With this change undefined build args will be set to empty string instead of string None Signed-off-by: Andrey Devyatkin <andrey.a.devyatkin@gmail.com>		2016-05-28 11:39:41 +02:00
