file system issue when i use vagrant+docker on windows

Question

this is my vagrant file

Vagrant.configure("2") do |config|
  config.vm.define "app" do |app|
    app.vm.provider "docker" do |d|
      d.build_dir = "."
      d.cmd = ["/sbin/my_init", "--enable-insecure-key"]
    end
  end
  config.ssh.username = "root"
  config.ssh.private_key_path = "insecure_key"
end

This is my docker file

FROM phusion/baseimage:0.9.15
MAINTAINER neetu

ENV HOME /root
RUN mkdir /buzzbuild
ADD . /buzzbuild
RUN cd /buzzbuild/ && chmod 777 install.sh && sh install.sh
CMD ["/sbin/my_init"]
EXPOSE 80 443 5000 15672

so as you can see .. 1) i am adding my buidl directory(.) to /buzzbuild 2) and am running a install script there (after i CD into that dir)

and i get

root@8bde177d1bc2:/buzzbuild# ./test2.sh -bash: ./install.sh: /bin/sh^M: bad interpreter: No such file or directory

the contents of the install script are :-

#!/bin/sh
#apt-get update
apt-get update
apt-get install -y -q git

If i create new file (test.sh) adn change permissions on it and add the same content it works.

but the install.sh script does not work.

I suspect its a problem of files getting added from windows to ubuntu(container)

any suggestions ?

what's wrong

The error message root@8bde177d1bc2:/buzzbuild# ./test2.sh -bash: ./install.sh: /bin/sh^M: bad interpreter: No such file or directory gives you a hint that your install.sh file has Windows style end of lines.

Windows end of lines are made of two characters: \\r\\n while Linux end of lines are just \\n . ^M represents the \\r character in the error message.

what to do

Either make sure all your scripts are using Linux style end of line before building your image or in your Dockerfile add a RUN statement that fixes end of lines:

ADD . /buzzbuild
RUN cd /buzzbuild/ \
    && sed -i 's/\r//' install.sh \
    && chmod 777 install.sh \
    && sh install.sh
