Use tfvars file |
Instructions on how to add your variables using tfvars file. |
Terraform allows you to define variable files called *.tfvars to create a reusable file for all the variables for a project. The following is an example that covers all of the required variables to run a majority of the Terraform examples in this repository.
If a particular module does not use a variable, you will see the following error. This error can be ignored.
│ Warning: Value for undeclared variable
│
│ The root module does not declare a variable named "operator_role_prefix" but a value was found in file
│ "terraform.tfvars". If you meant to use this value, add a "variable" block to the configuration.
│
│ To silence these warnings, use TF_VAR_... environment variables to provide certain "global" settings to all configurations in your organization. To
│ reduce the verbosity of these warnings, use the -compact-warnings option.

You may still define environmental variables. The exported values will override any of the variables in both the variables.tf file and the terraform.tfvars file.
The following example should serve as a basis for your own *.tfvars files. You can create multiple versions of this file, and then, apply and destroy using this file with the -var-file= flag.
This example only includes the variables needed for creating your account-wide roles and creating cluster with a managed OIDC configuration. You can also add the needed variables for creating your identity provider and machine pools to this file.
NOTE: The
tokenvalue in this example requires you to generate an offline OpenShift Cluster Manager token. You can do that in the Red Hat Hybrid Cloud Console.
account_role_prefix = "<user-prefix>"
availability_zones = ["<az-within-cloud-region>"]
cloud_region = "<aws-cloud-region>"
cluster_name = "<name-of-cluster>"
operator_role_prefix = "<user-prefix>
token = "<ocm-offline-token>"
url = "<url-of-environment"
