setup-terraform

The hashicorp/setup-terraform action is a JavaScript action that sets up Terraform CLI in your GitHub Actions workflow by:

Downloading a specific version of Terraform CLI and adding it to the PATH.
Configuring the Terraform CLI configuration file with a Terraform Cloud/Enterprise hostname and API token.
Installing a wrapper script to wrap subsequent calls of the terraform binary and expose its STDOUT, STDERR, and exit code as outputs named stdout, stderr, and exitcode respectively. (This can be optionally skipped if subsequent steps in the same job do not need to access the results of Terraform commands.)

After you've used the action, subsequent steps in the same job can run arbitrary Terraform commands using the GitHub Actions run syntax. This allows most Terraform commands to work exactly like they do on your local command line.

Usage

This action can be run on ubuntu-latest, windows-latest, and macos-latest GitHub Actions runners. When running on windows-latest the shell should be set to Bash.

The default configuration installs the latest version of Terraform CLI and installs the wrapper script to wrap subsequent calls to the terraform binary.

steps:
- uses: hashicorp/setup-terraform@v1

A specific version of Terraform CLI can be installed.

steps:
- uses: hashicorp/setup-terraform@v1
  with:
    terraform_version: 0.12.25

Credentials for Terraform Cloud (app.terraform.io) can be configured.

steps:
- uses: hashicorp/setup-terraform@v1
  with:
    cli_config_credentials_token: ${{ secrets.TF_API_TOKEN }}

Credentials for Terraform Enterprise can be configured.

steps:
- uses: hashicorp/setup-terraform@v1
  with:
    cli_config_credentials_hostname: 'terraform.example.com'
    cli_config_credentials_token: ${{ secrets.TF_API_TOKEN }}

The wrapper script installation can be skipped.

steps:
- uses: hashicorp/setup-terraform@v1
  with:
    terraform_wrapper: false

Subsequent steps can access outputs when the wrapper script is installed.

steps:
- uses: hashicorp/setup-terraform@v1

- run: terraform init

- id: plan
  run: terraform plan -no-color

- run: echo ${{ steps.plan.outputs.stdout }}
- run: echo ${{ steps.plan.outputs.stderr }}
- run: echo ${{ steps.plan.outputs.exitcode }}

Outputs can be used in subsequent steps to comment on the pull request:

defaults:
  run:
    working-directory: ${{ env.tf_actions_working_dir }}
steps:
- uses: actions/checkout@v2
- uses: hashicorp/setup-terraform@v1

- name: Terraform fmt
  id: fmt
  run: terraform fmt
  continue-on-error: true

- name: Terraform Init
  id: init
  run: terraform init

- name: Terraform Validate
  id: validate
  run: terraform validate -no-color

- name: Terraform Plan
  id: plan
  run: terraform plan -no-color
  continue-on-error: true

- uses: actions/github-script@0.9.0
  if: github.event_name == 'pull_request'
  env:
    PLAN: "terraform\n${{ steps.plan.outputs.stdout }}"
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    script: |
      const output = `#### Terraform Format and Style 🖌\`${{ steps.fmt.outcome }}\`
      #### Terraform Initialization ⚙️\`${{ steps.init.outcome }}\`
      #### Terraform Validation 🤖${{ steps.validate.outputs.stdout }}
      #### Terraform Plan 📖\`${{ steps.plan.outcome }}\`

      </details>
      
      *Pusher: @${{ github.actor }}, Action: \`${{ github.event_name }}\`, Working Directory: \`${{ env.tf_actions_working_dir }}\`, Workflow: \`${{ github.workflow }}\`*`;
        
      github.issues.createComment({
        issue_number: context.issue.number,
        owner: context.repo.owner,
        repo: context.repo.repo,
        body: output
      })

Inputs

The following inputs are supported.

cli_config_credentials_hostname - (optional) The hostname of a Terraform Cloud/Enterprise instance to place within the credentials block of the Terraform CLI configuration file. Defaults to app.terraform.io.
cli_config_credentials_token - (optional) The API token for a Terraform Cloud/Enterprise instance to place within the credentials block of the Terraform CLI configuration file.
terraform_version - (optional) The version of Terraform CLI to install. A value of latest will install the latest version of Terraform CLI. Defaults to latest.
terraform_wrapper - (optional) Whether or not to install a wrapper to wrap subsequent calls of the terraform binary and expose its STDOUT, STDERR, and exit code as outputs named stdout, stderr, and exitcode respectively. Defaults to true.

Outputs

This action does not configure any outputs directly. However, when the terraform_wrapper input is set to true, the following outputs will be available for subsequent steps that call the terraform binary.

stdout - The STDOUT stream of the call to the terraform binary.
stderr - The STDERR stream of the call to the terraform binary.
exitcode - The exit code of the call to the terraform binary.
