When using the OpenTelekomCloud Provider with Terraform 0.13 and later, the recommended approach is to declare Provider versions in the root module Terraform configuration, using a required_providers block as per the following example. For previous versions, please continue to pin the version within the provider block.

1. Add opentelekomcloud/opentelekomcloud to your required_providers.

   # provider.tf
   terraform {
     required_providers {
       opentelekomcloud = {
         source = "opentelekomcloud/opentelekomcloud"
         version = ">= 1.23.2"
       }
     }
   }

2. Run terraform init -upgrade to download the provider.

3. Add the provider and supply your tenant_name and domain_name for minimum configuration.

   # provider.tf
   provider "opentelekomcloud" {
     # OpenTelekomCloud Provider Documentation:
     # https://registry.terraform.io/providers/opentelekomcloud/opentelekomcloud/latest/docs
     # domain_name = "..."
     # tenant_name = "..."
     # auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
     # user_name   = "..."
     # password    = "..."
   }

4. Authenticate either by providing user_name and password in the previous file or setting them as environment variables.

   # Linux
   OS_USERNAME="<your_username>"
   OS_PASSWORD="<your_password"
   # Windows
   $env:OS_USERNAME="<your_username>"
   $env:OS_PASSWORD="<your_password"

5. Create your first resource.

   # main.tf
   
   # Create an Elastic Cloud Server resource
   resource "opentelekomcloud_compute_instance_v2" "test-server" {
     name        = "test-server"
     image_name  = "Standard_CentOS_8_latest"
     flavor_name = "s3.medium.1"
     key_pair        = "kp_ecs"
     security_groups = ["default"]
     network {
       name = "network_ecs"
     }
   }

Don't forget to fill in the required variables.

• Terraform 0.13+
• Go 1.15 (to build the provider plugin)

Clone repository to: $GOPATH/src/github.com/opentelekomcloud/terraform-provider-opentelekomcloud

$ export GO111MODULE=on
$ go get github.com/opentelekomcloud/terraform-provider-opentelekomcloud

Enter the provider directory and build the provider

$ cd $GOPATH/src/github.com/opentelekomcloud/terraform-provider-opentelekomcloud
$ make build

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.15+ is required).

To compile the provider, run make build. This will build the provider and put the provider binary in the current directory.

make build
...
$GOPATH/bin/terraform-provider-opentelekomcloud
...

In order to test the provider, you can simply run make test.

$ make test

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run.

$ make testacc
