Using Ansible to deploy Eden

1. Install Ansible with instructions from Ansible Doc

2. Create an EC2 Instance and launch it. From the Web UI, note the public ip, public dns and a part of the private dns (before .ec2.internal)

3. Create/Update /etc/ansible/hosts with the host information. Example

   <PUBLIC IP OF DB SERVER>
   <PUBLIC IP OF EDEN SERVER>
   <PUBLIC IP OF WEBSERVER SERVER>
   

4. cd to the repository and create a file, say, deploy.yml. Depending upon your deployment type (3-tier or single tier) copy the contents of either multiple.yml or single.yml from examples directory

5. Update the IPs and variables (refer to variable description below)

6. Finally, run ansible-playbook. ansible-playbook --private-key=<path_to_key> deploy.yml -u <remote_user> replacing <remote_user> with your server's remote user and <path_to_key> with path to private key associated with the server
