 # cloud-aws-stack
 Host default provisioning templates for Nuxeo
+
+## What's in this modules?
+
+This is a set of Terraform modules for configuring  infrastructure environments with AWS. 
+
+
+The Stack implements the current procedure at https://wiki.nuxeo.com/display/INFRA/Cloud+Provisioning
+
+
+* Create Subnets for the Stack
+    *    One Public with a /24 size. 
+    *    One private Subnet to run Nuxeo 
+    *    At least 2 Private Subnets for Databases
+* Create a NAT Gateway in one of the Public Subnets
+* Create a Route with the Internet Gateway as default route, associate it with the Public Subnet(s)
+* Create a Route with the NAT Gateway as default route, *_that should be associated to all Private Subnets when they are created_*
+* Create a Security Group for ELBs that accepts HTTP and HTTPS from anywhere
+* Create a Security Group for Bastion Hosts that accepts SSH from anywhere
+* Create a Bastion Host with bastion host SG associated to ti, install NTP and Userify on it
+
+
+## Requirements
+
+Before we start, you'll first need:
+
+* an AWS account with API access
+* locally configured AWS credentials 
+* to create a keypair in AWS
+* Download and install [terraform|https://www.terraform.io/downloads.html]
+
+
+## Quick Start
+
+To be able to use this stack create a terraform like:
+
+```
+module "nuxeo-env" {
+  source = "github.com/nuxeo/cloud-aws-stack"
+
+  stack_name = "acme"
+  vpc_id="vpc-8beb14ec"
+  public_subnets = ["10.0.10.0/24"]
+  private_subnets = ["10.0.11.0/24"]
+  private_db_subnets = ["10.0.100.0/24","10.0.101.0/24"]
+  public_key_path="/Users/<user>/.ssh/id_rsa.pub"
+}
+```
+
+Run:
+
+```
+terraform get
+terraform plan
+```
+
+You should get all that is going to be installed.
+
+If you want to see the resource dependency graph, install Graphviz and run:
+
+```
+terraform graph | dot -Tpng > graph.png
+```
