# Rancher Terraform DigitalOcean
Terraform module for a rancher server on Digitalocean.

### What you will get?

- A Rancher server running on DigitalOcean
- A Domain rule pointing to your Rancher server

### Features

- It works with your main DigitalOcean account or with DigitalOcean teams. For using a team you just need that team special token and your SSH keys installed there.
- It doesn't install puppet, chef or ansible on the host. Instead it uses [cloud-init](https://cloudinit.readthedocs.io/en/latest/).
- It closes all the external and internal traffic and the only ports opened are the `80` and `8080`.
- Login with root user is disabled, you will need your SSH keys.
- Iptables rules are persistent after reboot.
- You will get the new DigitalOcean beta metrics agent installed.

### What you will need?

- Terraform installed. This was tested with the 0.8.5 version. You can see terraform instructions [here](https://www.terraform.io/downloads.html).
- A DigitalOcean account. If you still don't have one you can create one [here](https://m.do.co/c/503f13cf640b) for free.
- You DigitalOcean token. You can get it from [here](https://cloud.digitalocean.com/settings/api/tokens).
- Public and private SSH keys on your local machine and set them up on your Digital Ocean account. You can learn how to do that [here](https://www.digitalocean.com/community/tutorials/how-to-use-ssh-keys-with-digitalocean-droplets).

### How to use it

Clone this repository

git clone git@github.com:lunagt/rancher-terraform-digitalocean.git

Inside the repository folder create a copy of the example `tfvars` file

cp terraform.example.tfvars terraform.tfvars

Edit this new file with the variables you want (see `variables` section at the end).

Runing it

terraform apply
    
If you don't need your server anymore, just destroy it

terraform destroy #and type 'yes' after this command
