+# docker-example
+An example Docker image creation from scratch.
+
+### Install Docker Machine
+
+Follow the procedure [here](https://docs.docker.com/machine/install-machine/) to install docker-machine. Machine let's you start virtual hosts using virtual-box (in our case) and run docker on it.
+
+Note: you can run the following natively too. I'm using a virtual host to keep the dev env isolated.
+
+Get some help using :
+
+```sh
+$ docker-machine --help
+```
+
+### Create a VM (dev) running boot2docker
+
+Let's create a machine (virtual host). Ensure virtual-box is installed and running on your local machine.
+
+```sh
+$ docker-machine create --driver virtualbox dev
+
+$ docker-machine env dev (shows the new VM env configuration)
+
+# Copy the project's Dockerfile | package.json | server.js files into the VM.
+
+$ docker-machine scp -r . dev:/home/docker/
+
+$ docker-machine ssh dev (to login into the new VM)
+
+(optional)
+
+$ docker-machine start dev (start the VM)
+
+$ docker-machine stop dev (stop the VM)
+
+$ docker-machine ls (show list of VMs)
+
+$ docker-machine kill dev (kill the VM)
+
+$ docker-machine rm dev (to remove the VM completely)
+```
+
+### Getting Started
+
+Once you have ssh into `dev` VM which is a boot2docker image. You should see that `docker` is pre-installed on it. You are ready to start off.
+
+```sh
+
+$ docker build -t ksck23/node .
+
+$ docker run -it --rm --name app ksck23/node
+```
