tfrunner 0.12.1

A cli tool used to make running terraform or opentofu project simpler. Includes secret fetching and remote state management.

Tfrunner

Welcome to tfrunner, a cli tool to run terraform commands with the following facilities:

• Multi-project support
• Automation support
• Remote backend
• GitLab secrets pulling

Installation

Since tfrunner is a cli tool, the recommended installation is using pipx.

Please ensure you have a compatible python >= 3.12 version.

Install with: pipx install tfrunner

Usage

Requirements: tfrunner expects the following binaries to be installed:

• terraform: tfrunner is a wrapper on top of terraform
• git: when using the --git-sandbox flag, ensure you have git installed and that you are running the command in a git project

To use it to manage multiple projects, create a yaml file configuring each.

Here is an example file, let's name it tfrunner.yaml:

flavour: terraform # Can use tofu

state_backend:
  kind: gitlab
  spec:
    url: https://gitlab.com
    project_id: 12345678
    token_var: GITLAB_TOKEN

secrets_backend:
  kind: gitlab
  spec:
    url: https://gitlab.com
    project_id: 12345678
    token_var: GITLAB_TOKEN

tfvars:
  gitlab_token: $GITLAB_TOKEN

projects:
  dev: # Reflects name of the environment
    path: ../infra/dev
    state_name: dev
    # Inner environment gets added (and overrides colliding vars) with global env vars
    # env vars take precedence over secrets
    tfvars:
      doppler_token: $DOPPLER_TOKEN
    # Inner secrets backend takes precendence
    secrets_backend:
      kind: doppler
      spec:
        project: my-project
        config: dev
        token_var: DOPPLER_TOKEN

Now you can run tfrunner as you would run any regular terraform command (options are also included). You need only to be wary of two additional arguments that are needed:

• --project: name of your project, as specified in your config file.
• --config_path: path to your configuration file. By default it will look for a tfrunner.yaml file in the current folder

As examples, for the great-project in our example tfrunner.yaml file, you could run:

tfrunner init --project great-project
tfrunner fmt --project great-project
tfrunner validate --project great-project
tfrunner plan --project great-project
tfrunner apply --project great-project
tfrunner destroy --config_path tfrunner.yaml --project great-project

The --config_path is optional in the tfrunner destroy command, as tfrunner will by default assume its path to be tfrunner.yaml.

Usage with git-sandboxes

tfrunner init --project great-project --git-sandbox
tfrunner plan --project great-project --git-sandbox
tfrunner apply --project great-project --git-sandbox
tfrunner destroy --project great-project --git-sandbox

Local development

Requirements:

• uv installed
• terraform installed
• git installed

1. Install virtual environment: uv sync --all-groups

TODO:

• Make tfrunner plan generate a plan file by default
• Make tfrunner apply use that plan file by default
