GitHub Actions for setting up environment variables for Terraform Cloud

With this action you can make available environment variables for further interaction with Terraform Cloud using actions such as the create workflow action.

• This action populates the following environment variables
  • TERRAFORM_CLOUD_TOKEN with an API-token for authentication (required)
  • TERRAFORM_CLOUD_ORGANIZATION with the name of the Terraform Cloud organization
  • TERRAFORM_CLOUD_PROJECT with the name of the Terraform Cloud project to use
  • TERRAFORM_CLOUD_WORKSPACE with the name of the Terraform Cloud workspace to use
• If no value is provided for a property then you will need to provide the corresponding value as input to further actions instead.

Sample workflow

Below is a full sample workflow that sets up a new workspace in Terraform Cloud when a pull-request is opened, and deletes the workspace once the pull-request is closed. If the pull request is opened for a branch named feature-1 the resulting workspace will be named my-workspace-feature-1 in this sample.

name: Terraform Cloud workspaces for pull-requests

on:
  pull_request:
    types:
      - opened
      - closed

env:
  ORGANIZATION: my-terraform-cloud-organization
  PROJECT: my-terraform-cloud-project
  WORKSPACE: my-workspace-${{ github.head_ref }}

  create-workspace:
    if: ${{ github.event.action == 'opened' }}
    runs-on: ubuntu-latest
