[![Build](https://travis-ci.org/joemccann/dillinger.svg?branch=master)](https://travis-ci.org/joemccann/dillinger)

## Description
It's just an ansible playbook and that the playbook installs docker and builds a nodejs image from a docker file and that docker file fetched from an another repository and after then that image push to your docker hub.

- Docker installation and image build and push through the same playbook

----
## Pre-Requests
- Install Ansible on your Master Machine
- Basic Knowledge of ansible
- Basic Knowledge of docker
- Need a docker hub account

##### Installation
[Ansible2](https://docs.ansible.com/ansible/2.3/index.html) (For your reference visit [How to install Ansible](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html))

----

## Reference
On this playbook was I used my old [nodjs](https://github.com/yousafkhamza/nodejs-dockerfile) docker file to create image so please be check the same. So, that repo cloned to a destination through ansible and genrated the image from this.

----
## Conclusion
It's just creating a docker image through ansible and then push that same to Docker hub.
