Simple "hello world" test with Docker and Mono

This example will run a simple C# console application in a Ubuntu Docker container.

The application will print "Hello Mono!" to the console.

Step 1

####Set up a vagrant box to run the example on

######Open a command prompt and run:

$ vagrant init phusion/ubuntu-14.04-amd64
$ vagrant up

######SSH into the VM with:

$ vagrant ssh

######Install Docker in the VM with:

 $ sudo apt-get update
 $ sudo apt-get install docker.io
 $ sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker
 $ sudo sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io

Step 2

######Copy the "MonoDockerTest" folder to the VM with SCP:

$ scp -P 2222 -r MonoDockerTest vagrant@127.0.0.1:/home/vagrant/DockerTest/

username: vagrant

password: vagrant

Step 3

######In the VM:

1. Navigate to the folder with the Dockerfile

2. Build the Docker image with the following command:

   $ sudo docker build -t hello .
   

3. Run the Docker container with the following command:

   $ sudo docker run hello
   

It should output:

Hello Mono!
