Terraform is a provider agnostic framework to create and maintain infrastructure on public clouds. To interface with actual providers, Terraform comes with a modular architecture. To access the Open Telekom Cloud (OTC) the OpenStack provider can be used as the OTC implements a lot of OpenStack APIs. This project includes example projects for different use cases users can adopt as a starting point for their own installations.
The examples in this repository are testet with:
- Terraform: v0.11.7
- OpenStack Provider: 1.6.0
| Terraform Resource | Status |
|---|---|
| Data Sources | Working |
| Block Storage | Working |
| Compute | Working |
| DNS | Working |
| Images | Working |
| Networking | Working |
| Load Balancer | Working |
| Firewall | Not working |
The floatingip association problem is fixed in the lastest version of Terraforms OpenStack provier (1.6.0). I've used this opprotunity to update all terraform examples to work with the newest version of Terraform (v0.11.7).
There are different examples of Terraform scripts, each with a different purpose:
minimal
A minimal Terraform example with just the components to get a virtual machine running and connect to it with a public ip. If you are new to Terraform, this is the recommended example to start with.
dns
A bit more complex example, inlcuding handling of DNS and additional storage volumes. If you already worked with Terraform or you got the minimal example running and want to explore more, try this example.
objectstorage
An example on how to use the object storage that is included in OTC by utilizing the AWS provider.
provisioner
This based on the minimal example, showing the usage of Terraform's provisioner to execute commands and deploy files on the created instances.

full
A complete example, showing the full power of terraform. Components can be enabled and disabled via configuration file. This can be used as a template for production grade Terraform scripts.
modules
One strong argument for Terraform is the option to create reusable modules. This example shows how easy it is to create a full infrastructure deployment on the OTC by utilizing the Terraform modules provided in the terraform-otc-module repository.
- Install Terraform.
- Clone this repository via
git clone https://github.com/OpenTelekomCloud/terraform-otc.git. - Switch to terraform directory
cd terraform-otc/minimal. - Initialize Terraform provider via
terraform init. - Insert your login information into
parameter.tvars(see next section). - Check if everything looks fine with
terraform plan -var-file=parameter.tvars. - Apply the changes via
terraform apply -var-file=parameter.tvars.
All variables that can be changed are documented in variables.tf. There are reasonable default values for most of the variables in this file. Every variable may be overwritten by passing command line arguments to the Terraform invocation, or simply by passing a parameter file via the -var-file command line parameter. All the examples provide a file parameters.tvars containing all necessary parameters for the example to work (for example your login information). You can add more parameters for any variable existing in the variables.tf file. For more information see Terraform variables documentation.
To get the examples to work with you OTC account, you need three information bits:
- username (user name from
My Credential) - password (your login password)
- domain_name (Domain Name from
My Credential)
Refer to the OTC Helpcenter documentation article to find authentication details:
