nginx deployed through terraform and ansible Purpose This Terraform deployment will set up a floating IP, 2 nodes with Nginx configures as load balancers, and 2 web nodes. Provisioning will be handled by Terraform and configuration will be done with Ansible. The repo used can be located here . Prerequisites You’ll need to install Terraform which will be used to handle Droplet provisioning. In order to apply configuration changes to the newly provisioned Droplets, Ansible needs to be installed. Ansible’s inventory will be handled by Terraform, so you’ll need terraform-inventory . We’re going to need a DigitalOcean API key. The steps to generate a DigitalOcean API key can be found here . Use the included gen_auth_key script to generate an auth key for your load balancing cluster. Configuring Let’s get Terraform ready to deploy. We’re going to be using terraform.tfvars to store values required such as API key, project name, SSH data, the number of backe...
