# Terraform Configurations

You can find the configurations required for provisioning on your cloud provider on the following GitHub repository.

It is possible to customize the following provisioning variables as needed:

<table><thead><tr><th width="174">Variable</th><th width="249.33333333333331">Definition</th><th>Default</th></tr></thead><tbody><tr><td>region</td><td>Cloud region to provision the cluster on</td><td>"eu-north-1"</td></tr><tr><td><a data-footnote-ref href="#user-content-fn-1">vpc_id</a></td><td>ID of VPC to add cluster to</td><td>-</td></tr><tr><td>zones</td><td>Zones to user for the cluster</td><td>["eu-north-1b"]</td></tr><tr><td>cluster_name</td><td>Name to assign to provisioned cluster</td><td>"rierino-cluster"</td></tr><tr><td>static_ips</td><td>Names of static ips to allocate for services</td><td>[ "admin-gateway-lb-ip", "h2owave-lb-ip", "admin-ui-lb-ip" ]</td></tr><tr><td>node_pools</td><td>List of node pool definitions to provision</td><td><p>[ </p><p>{ name = "admin" instance_size = "small" desired_size = 1 min_size = 1 max_size = 2 }, </p><p>{ name = "ui" instance_size = "medium" desired_size = 1 min_size = 1 max_size = 2 }, </p><p>{ name = "infra" instance_size = "small" desired_size = 1 min_size = 1 max_size = 2 }, </p><p>{ name = "ops" instance_size = "large" desired_size = 1 min_size = 1 max_size = 2 } </p><p>]</p></td></tr><tr><td>admin_cidr</td><td>CIDR for static IP addresses to grant admin access to</td><td>-</td></tr></tbody></table>

**Where do we draw the line between Terraform & Ansible?**

We use Terraform strictly for provisioning of cloud vendor specific resources (e.g. cluster, node pools, security groups).

Any application installation, configuration or kubernetes deployment is done using Ansible.&#x20;

[^1]: A new VPC is not created automatically as it is preferred to add Rierino to an existing VPC in most cases.
