+# Terraform setup for DigitalOcean
+
+This is a teraform setup for my LPI Labs. The servers are deployed on DigitalOcean. The DNS is automatically updated with the server names.
+
+## Prerequisites
+
+* Install *Terraform* on your local host:
+
+```
+$ wget https://releases.hashicorp.com/terraform/0.11.7/terraform_0.11.7_linux_amd64.zip
+$ unzip terraform_0.11.7_linux_amd64.zip
+$ sudo cp terraform /usr/local/bin
+```
+
+## Instructions
+
+* Get the repo
+
+```
+$ git clone https://git.theo-andreou.org/Personal/lpi-deploy-digitalocean.git
+$ cd terraform-scaleway
+```
+
+* Copy the *terraform.tfvars.example* to *terraform.tfvars* and setup your settings:
+
+```
+do_token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+domain = "example.org"
+count = 14
+
+server_name = {
+  "debian" = "lpi-deb"
+  "centos" = "lpi-centos"
+}
+
+images = {
+  "debian" = "debian-9-x64"
+  "centos" = "centos-7-x64"
+}
+
+ssh_keys = [
+    "xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx",
+]
+
+dns_server = "ns1.example.org"
+dns_key_name = "control.ns1.example.org"
+dns_key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/xxxxxxxxxxxxxxxxxxxxxxxxxxx+xxxxxxxxxxxxxxxxxxxxx+xxx=="
+```
+
+* Initialize your *Terraform* environment:
+
+```
+$ terraform init
+``` 
+
+* Create a *Terraform* plan:
+
+```
+$ terraform plan -out lpi.plan
+```
+
+* Apply the plan:
+
+```
+$ terraform apply "lpi.plan"
+```
+
