elastx/terraform-demo

Created to demonstrate the power of Hashicorps Terraform

Terraform Demo

This is just a quickstart for using terraform on Elastx. It creates:

#	Resource
1	Router
2	Subnets, web and db
4	instances, 2 web, 2 db
2	floating IPs for web cluster
2	Server Groups with anti-affiniy (web, db) makes sure instances aren't on same physical hardware
3	Security Groups "demo-ssh-sg", "demo-web-sg" and "demo-db-sg"
1	Key pair "demo_rsa"

Default user is changed to "elastx" with cloud-config.

File structure

Name	Description
README.md	This file, obviously
demo_rsa(|\.pub)	SSH keypair, only to be used for this demonstration
terraform.tf	The terraform manifest with all defined resources
terraform-openrc.sh	should be run initially to setup username, tenant and password
terraform.tfstate(|\.backup)	tfstate and tfstate.backup so that terraform can keep track on changes

How to use

Make sure you have installed Terraform

First off, run the terraform-openrc.sh script. It will ask about username, tenant and password. Then run "terraform plan". If that fails, make sure you've used the correct credentials (runt terraform-openrc.sh again)

Last, "terraform apply" will install

$ . ./terraform-openrc.sh
[...]
$ terraform init (if it is the first time you run terraform)
$ terraform plan
$ terraform apply

You should now have a fully working environment with everything described in the beginning of this README.
