Cloud Posse

Terraform module to provision workspaces & configurations in Terraform Cloud via YAML configuration.

NOTE: Requires Terraform Cloud or Terraform Enterprise.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

Here's how to invoke this example module in your projects:

provider "tfe" {
  version  = ">= 0.21.0"
}

module "example" {
  source = "https://github.com/cloudposse/terraform-tfe-cloud-infrastructure-automation.git?ref=master"

  # Directory containing all YAML configurations
  config_file_path = "config"
  organization     = var.organization

  vcs_repo = {
    branch             = "main"
    ingress_submodules = true
    # We recommend exporting the `FOOBAR` environment variable instead of passing a variable
    oauth_token_id     = var.oauth_token_id
  }
}

Examples

Here is an example of using this module:

We use YAML for the configuration files in order to separate configuration settings from business logic. It's also a portable format that can be used across multiple tools. Our convention is to name files by $env-$stage.yaml (e.g. ue2-testing.yaml), so for example an $env could be ue2 (for us-east-2) and the $stage might be testing. Workspace names are derived from the $env-$stage-$project, which looks like ue2-testing-eks.

# Projects are all the top-level root modules
projects:
  # Globals are exported as TF_VAR_... environment variables in every workspace
  globals:
    # Used to determine the name of the workspace (e.g. the 'testing' in 'ue2-testing')
    stage: testing
    # Used to determine the name of the workspace (e.g. the 'ue2' in 'ue2-testing')
    environment: ue2

  # The configuration file format is designed to be used across multiple tools.
  # All terraform projects should be listed under this section.
  terraform:
    # List one or more Terraform projects here
    first-project:
      # Controls whether or not this workspace should be created
      # NOTE: If set to 'false', you cannot reference this workspace via `triggers` in another workspace!
      workspace_enabled: true
      # Override the version of Terraform for this workspace (defaults to the latest in Terraform Cloud/Enterprise)
      terraform_version: 0.13.4
      # Controls the `auto_apply` setting within this workspace
      auto_apply: true
      # Optional filename triggers to match (default is *.tf)
      filename_triggers:
        - "*.*"
      # Add extra 'Run Triggers' to this workspace, beyond the parent workspace, which is created by default
      # These triggers mean this project workspace will be automatically planned if any of these workspaces are applied.
      triggers:
        - uw2-testing-example2
        - gbl-root-example1
      # Set the Terraform input variable values for this project. Complex types like maps and lists are supported.
      vars:
        my_input_var: "Hello world! This is a value that needs to be passed to my `first-project` Terraform project."
    # Every project should be uniquely named and correspond to a folder in the `projects/` directory
    second-project:
      workspace_enabled: true
      # Specify a custom project folder (defalts to the project name if not specified)
      custom_project_folder: my-custom-project-folder
      vars:
        my_input_var: "Hello world! This is another example!"
