Ansible EC2 Play Framework

This is a set of Ansible scripts to deploy Play 2 projects in EC2 instances.

Steps to use:

• edit hosts.ini and set your ec2 instance(s) name

• edit config/postfix_selections to set domains for email

• Add Amazon AWS keys to your ssh repository:

  ssh-agent
  ssh-add ~/path/to/foo.pem

• Run the ansible scripts:

  ansible-playbook -i hosts.ini script_name.yaml -u ubuntu (--sudo)

And done. Your EC2 isntance should be ready to go.

Scripts

Scripts may contain variables that need to be customized for your specific deployments. The following scripts are available:

• bootstrap.yaml: secures an EC2 Ubuntu AMI. Requires sudo.
• playenv.yaml: sets play dependencies (pvm, java) including Authbind so Play can use port 80 without root privileges. Requires sudo.
• deploy.yaml: clones a Play project from a Git repository and deploys it on the machine. No sudo required.

WARNING: I'm no sysadmin, so the scripts may contain some big mistake (especially in the security part), so be careful when executing them and be sure you understand what you are doing. WARNING: if you use a Micro EC2 instance the deployment script will fail (ubuntu will kill the build due to lack of memory), you will need to do that part manually

Start file

The settings assume the use of Authbind so Play can run on port 80 without root privileges. A start file is provided under folder exec that can be used as a template for your own start file.

Deployment scripts assume you place your customized start file at the root of the project cloned via git. Modify the script accordingly if that's not the case.
