# Purpose

Spins up a [Docker](https://www.docker.com) Swarm mode cluster within a
[Vagrant](https://www.vagrantup.com) environment and uses
[Ansible](https://www.ansible.com) to provision the whole environment.

## Requirements

- [Ansible](https://www.ansible.com)
- [VirtualBox](https://www.virtualbox.org)
- [Vagrant](https://www.vagrantup.com)

## Information

This environment will consist of the following:
- 7 [Ubuntu] 16.04 nodes
- 3 [Docker] Swarm Managers (node0-node2)
- 4 [Docker] Swarm Workers (node3-node6)

- 7 [Ubuntu](https://www.ubuntu.com) `16.04` nodes
- 3 [Docker](https://www.docker.com) Swarm Managers (node0-node2)
- 4 [Docker](https://www.docker.com) Swarm Workers (node3-node6)

I have also included a [Python] script `docker-management.py` that will be
worked on over time to do some initial various things but will have more
functionality over time.

Usage
-----
Easily spin up the [Vagrant] environment.
```
## Usage

Easily spin up the [Vagrant](https://www.vagrantup.com) environment.

```bash
vagrant up
```
Once everything provisions you are now ready to begin using your [Docker] Swarm
