Role Variables

Variable Description Default Value
terraform_min_version Specify a minimum version of Terraform, eg. 0.11.0. Specify false to skip. false

Example Playbook

The aim of this role is to create a workflow in Ansible that supports Terraform workflow of "plan, then apply". It also supports ensuring that the minimum and maximum versions of Terraform are met. (eg. If you have a pre Terraform 0.12 project that cannot be updated).
