# Terraform/Module-Base
#
# The purpose of this template is to provide flexibility to the user so
# they are able to only include the jobs that they find interesting.
#
# Therefore, this template is not supposed to run any jobs. The idea is to only
# create hidden jobs. See: https://docs.gitlab.com/ee/ci/yaml/#hide-jobs
#
# There is a more opinionated template which we suggest the users to abide,
# which is the lib/gitlab/ci/templates/Terraform-Module.gitlab-ci.yml

# These variables may be overridden by the pipeline including it to control how the Terraform module is being deployed.
variables:
  TERRAFORM_MODULE_DIR: ${CI_PROJECT_DIR}    # The relative path to the root directory of the Terraform project.
  TERRAFORM_MODULE_NAME: ${CI_PROJECT_NAME}  # The name of your Terraform module, must not have any spaces or underscores (will be translated to hyphens).
  TERRAFORM_MODULE_SYSTEM: local             # The system or provider your Terraform module targets (ex. local, aws, google).
  TERRAFORM_MODULE_VERSION: ${CI_COMMIT_TAG} # The version - it's recommended to follow SemVer for Terraform Module Versioning.
