Environment Variables

GITHUB_DOT_COM_TOKEN

This is used to specify a token for GitHub.com when the action is running on a GitHub Enterprise instance. This is only used for downloading OpenTofu binaries from GitHub.com. If this is not set, an unauthenticated request will be made to GitHub.com to download the binary, which may be rate limited.
- Type: string
- Optional
TERRAFORM_CLOUD_TOKENS

API tokens for cloud hosts, of the form <host>=<token>. Multiple tokens may be specified, one per line. These tokens may be used with the remote backend and for fetching required modules from the registry.

e.g:
```
env:
  TERRAFORM_CLOUD_TOKENS: app.terraform.io=$
```
With other registries:
```
env:
  TERRAFORM_CLOUD_TOKENS: |
    app.terraform.io=$
    terraform.example.com=$
```
- Type: string
- Optional
TERRAFORM_SSH_KEY

A SSH private key that Terraform will use to fetch git/mercurial module sources.

This should be in PEM format.

For example:
```
env:
  TERRAFORM_SSH_KEY: $
```
- Type: string
- Optional
TERRAFORM_HTTP_CREDENTIALS

Credentials that will be used for fetching modules sources with git::http://, git::https://, http:// & https:// schemes.

Credentials have the format <host>=<username>:<password>. Multiple credentials may be specified, one per line.

Each credential is evaluated in order, and the first matching credentials are used.

Credentials that are used by git (git::http://, git::https://) allow a path after the hostname. Paths are ignored by http:// & https:// schemes. For git module sources, a credential matches if each mentioned path segment is an exact match.

For example:
```
env:
  TERRAFORM_HTTP_CREDENTIALS: |
    example.com=dflook:$
    github.com/dflook/terraform-github-actions.git=dflook-actions:$
    github.com/dflook=dflook:$
    github.com=graham:$  
```
- Type: string
- Optional
TERRAFORM_PRE_RUN

A set of commands that will be ran prior to terraform init. This can be used to customise the environment before running Terraform.

The runtime environment for these actions is subject to change in minor version releases. If using this environment variable, specify the minor version of the action to use.

The runtime image is currently based on debian:bullseye, with the command run using bash -xeo pipefail.

For example:
```
env:
  TERRAFORM_PRE_RUN: |
    # Install latest Azure CLI
    curl -skL https://aka.ms/InstallAzureCLIDeb | bash
      
    # Install postgres client
    apt-get install -y --no-install-recommends postgresql-client
```
- Type: string
- Optional
