Terraform provider for Dimension Data cloud compute.

dd-cloud-compute-terraform

Terraform provider for Dimension Data cloud compute.

Currently, the following resource types are supported:

• ddcloud_networkdomain: A network domain
• ddcloud_vlan: A VLAN
• ddcloud_server: A virtual machine
• ddcloud_server_anti_affinity: An anti-affinity rule between 2 servers
• ddcloud_nat: A NAT rule (forwards traffic from a public IPv4 address to a server's internal IPv4 address)
• ddcloud_firewall_rule: A firewall rule
• ddcloud_vip_node: A Virtual IP (VIP) node.
• ddcloud_vip_pool: A Virtual IP (VIP) pool.
• ddcloud_vip_pool_member: A Virtual IP (VIP) pool membership (node -> pool).

For more information, see the provider documentation.

Installing the provider

Download the latest release and place the provider executable in the same directory as the main Terraform executable.

Building the provider yourself

If you want to build the provider yourself instead of installing a pre-built release, see CONTRIBUTING.md.

Testing the provider

Create a folder containing a single .tf file:

/*
 * This configuration will create a single server running CentOS and expose it to the internet on port 80.
 *
 * By default, the CentOS image does not have http installed (`yum install httpd`) so there's no problem exposing port 80.
 */

1. Run terraform plan -out tf.plan.
2. Verify that everything looks ok.
3. Run terraform apply tf.plan
4. Have a look around and, when it's time to clean up...
5. Run terraform plan -destroy -out tf.plan
6. Verify that everything looks ok.
7. Run terraform apply tf.plan
