Security Warning

[PeterHuizing]

When I am building in a working directory with a lot of files, the docker build command is running a long time and gives a security warning and a timeout..
$ docker build -t helloworld .
SECURITY WARNING: You are building a Docker image from Windows against a Linux Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

Did you issue this command from a Cygwin or a similar shell on a Windows machine?

Hi Arun,
I used git-bash.
Another contribution: I found during the lab an issue using docker-commands in git-bash. Using the '-ti' -options resulted in "cannot enable tty mode on non tty input". I solved it with prepending the docker command with 'winpty'
For example: $ winpty docker run -ti mywildfly
