ga-terraform-cloud

An action to run Terraform Cloud workspaces

Fork of https://github.com/addresscloud/terraform-cloud-action

This Action was based on the example Terraform Enterprise script at: https://github.com/hashicorp/terraform-guides/tree/master/operations/automation-script

This action submits a run to a Terraform Cloud workspace which performs a plan and apply. Once the run is successfully submitted the action returns a success, leaving the plan and apply to continue to run in Terraform Cloud.

Usage

Terraform Cloud requires a .tar.gz archive containing the Terraform configuration, and build artifacts if required. The example shows a GitHub workflow archiving Lambda functions (in the build directory) alongside a Terraform configuration (in the infrastructure directory) for deployment. The archive is then passed to the action for deployment by Terraform Cloud.

- name: Create tar gz file
  run: tar --exclude *.terraform* -zcvf build.tar.gz build infrastructure

- name: Terraform Cloud
  uses: addresscloud/[email protected]
  with:
    tfToken: ${{ secrets.TERRAFORM_TOKEN }}
    tfOrg: '<ORGANISATION>'
    tfWorkspace: 'my-lambda-service'
    filePath: './build.tar.gz'
    identifier: ${{ github.sha }}

Example workflow

Inputs

The inputs below are required by the action to submit the run to Terraform Cloud. Additional workspace variables and settings should be configured using the Terraform Cloud UI.

tfToken

Required - Terraform Cloud access token.

tfOrganization

Required - Terraform Cloud organization.

tfWorkspace

Required - Name of existing Terraform Cloud workspace.

filePath

Required - Path to .tar.gz archive with Terraform configuration.

identifier

Required - Unique identifier for the run (e.g. git commit sha). Reduced to 7 characters for brevity.

Outputs

runId

The identifier of the run in Terraform Cloud.

Notes

If your repository contains multiple modules, upload the top-level directory and configure the root workspace path in the Terraform Cloud UI. For example, to deploy infrastructure/dev/services/lambda/main.tf which has references to modules in infrastructure/modules/services/lambda/module.tf upload the entire infrastructure directory and configure infrastructure/dev/services/lambda/ as the root of the workspace in the Terraform Cloud UI.
