DKAN on AWS

Sets up creating DKAN instances in AWS using CloudFormation. Sets up an instance with ElasticLoadBalancer in front of an AutoScale Group of EC2 webservers that connect to an RDS instance.

This currently includes two roles:

• dkan_aws_as_cf - CloudFormation template for setting up new instances of a HA DKAN site
• dkan_aws_network - Creates VPC for instances created by dkan_aws_as_cf

Requirements

Requires: https://github.com/boto/boto

Example Playbook

This includes two example projects, the cities "Mos Eisley" and "Cloud City".

To spin up the stack-wide VPC:

ansible-playbook network.yml

To spin up instances for the two cities:

ansible-playbook instances.yml

To change the number of default webservers for "Cloud City", add webserver_capicity: 3 to inventory/host_vars/bespin-cloud-city and rerun the instances.yml playbook.
