The terraform gen_tfvars ansible role

The gen_tfvars ansible role is used to let us generate the terraform variables we need for cloud environments.

terraform/terraform.tfvars

The default kdevops_terraform_tfvars path is terraform/terraform.tfvars. So we generate the terraform/terraform.tfvars using jinja2 template, and each cloud provider can define its own other variables.

Dependency on gen_nodes ansible role

The gen_tfvars ansible has a dependency on the gen_nodes ansible role as well to generate the terraform variable kdevops_nodes. See the docs:

• What are and how to generate the kdevops nodes files
  • gen_nodes for terraform

TODO

It should be possible to automatically generate Kconfig variables for cloud providers based on input from a real tool from a cloud provider. This should be able to leverage the dynamic kconfig nature of kdevops.
