Run the Terraform template to create servers and populate the inventory file

Run the Ansible playbook to configure all instances in all groups

This approach has some flaws, though. For example, it doesn't handle deleted servers: if the instance is gone from the Terraform template, it will still exist in the inventory file generated previously, leading to failed Ansible runs. We also don't have any indicator of SSH being ready: if we stay with this approach, we have to basically guess if than instance is ready to be SSHed to. Not good!

It would be nice if Terraform had built-in Ansible support, but it's not the case yet. However, there is a small utility named terraform-inventory that generates dynamic Ansible inventory from the Terraform state file. It is available for download on GitHub at https://github.com/adammck/terraform-inventory. You need to use it after running Terraform, as follows:
