Wikipedia defines Docker as

An open-source project that automates the deployment of applications inside software containers...provides an additional layer of abstraction and automation of operating-system-level virtualization on Windows and Linux.

In simpler words

Docker is an open-source tool to build and deploy your distributed applications easily in a sandbox that can be run on any linux host later

(called container later)

CONTAINERS ! What are those ?

Containers are like VMs !

This is how VMs works

This is how actually containers works

Containers are

Created based on

Docker images

This is your base image

This is a container

To run and distribute

Docker containers

YOU NEED

A Docker Daemon

DOCKER HOST

DOCKER DAEMON

DOCKER containers

Tensorflow

REDIS

CHATBOT

Web APP

To interact with the

docker daemon

you must have

a Docker Client

DOCKER HOST

Dockerfile

FROM ubuntu
MAINTAINER Ouadie LAHDIOUI

RUN apt-get install -y software-properties-common python
RUN add-apt-repository ppa:chris-lea/node.js
RUN echo "deb http://us.archive.ubuntu.com/ubuntu/ precise universe" >> /etc/apt/sources.list
RUN apt-get update
RUN apt-get install -y nodejs
#RUN apt-get install -y nodejs=0.6.12~dfsg1-1ubuntu1
RUN mkdir /var/www

ADD app.js /var/www/app.js
