Torrust Tracker Deployer

⚠️ DEVELOPMENT STATUS: Not Production-Ready

This project is currently in active development and is not production-ready. It currently only supports local deployment using LXD virtualization for development and testing purposes.

Current Scope:

✅ Local LXD virtual machine provisioning

✅ Development and testing workflows

❌ No real cloud provider support (AWS, GCP, Azure, Hetzner, etc.)

❌ No production deployment capabilities

📋 MVP Goal: After completing the roadmap, we will have a Minimum Viable Product (MVP) that supports real cloud providers and production deployments.

This Rust application provides automated deployment infrastructure for Torrust tracker projects. Currently focused on local development and testing, it manages VM provisioning and cloud-init execution using LXD virtual machines. The goal is to establish the foundational deployment patterns that will later support real cloud providers.

🎯 Project Goals

Current Development Phase:

✅ Create local VMs supporting cloud-init for development and CI testing
✅ Test cloud-init execution and verification in controlled environments
✅ Support Docker Compose inside VMs for application stacks
✅ Fast, easy to install and use local development solution
✅ No nested virtualization dependency (CI compatibility)

Future MVP Goals: (See roadmap)

🔄 Real cloud provider support (Hetzner, AWS, GCP, Azure)
🔄 Production deployment capabilities
🔄 Multi-environment management

🔧 Local Development Approach

This repository uses LXD virtual machines for local virtualization and development:

☁️ LXD Virtual Machines (`templates/tofu/lxd/`) - LOCAL DEVELOPMENT

Technology: Virtual machines with cloud-init support
Status: ✅ Production-ready for local development and CI testing
Best for: Local development, CI/CD environments, fast iteration
Requirements: No special virtualization needed

🚀 Quick Start

📋 Prerequisites

This is a Rust application that automates deployment infrastructure using OpenTofu and Ansible.

Automated Setup (Recommended)

The project provides a dependency installer tool that automatically detects and installs required dependencies:

# Install all required dependencies
cargo run --bin dependency-installer install

# Check which dependencies are installed
cargo run --bin dependency-installer check

# List all dependencies with status
cargo run --bin dependency-installer list

The installer supports: OpenTofu, Ansible, LXD, and cargo-machete.

For detailed information, see 📖 Dependency Installer →.

Manual Setup

If you prefer manual installation or need to troubleshoot:

Check installations:

lxd version && tofu version && ansible --version && cargo --version

Missing tools? See detailed installation guides:

Quick manual install:

# Install Rust (if not already installed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Install LXD
sudo snap install lxd && sudo lxd init --auto && sudo usermod -a -G lxd $USER && newgrp lxd

# Install OpenTofu
curl -fsSL https://get.opentofu.org/install-opentofu.sh | sudo bash

# Install Ansible
sudo apt install ansible

💻 Usage

🚀 Main Application

The main application provides usage instructions:

# Build and run the application
cargo run

# Or install and run directly
cargo install --path .
torrust-tracker-deployer

For detailed usage instructions, command reference, and examples, see the 👤 User Guide.

The application includes comprehensive logging with configurable format, output mode, and directory. See 📖 Logging Guide for details on logging configuration options.

🔧 Development Tasks

This project includes convenient scripts for common development tasks:

# Run all linters (markdown, YAML, TOML, shell scripts, Rust)
cargo run --bin linter all

Or run individual linters:

cargo run --bin linter markdown    # Markdown linting
cargo run --bin linter yaml        # YAML linting
cargo run --bin linter toml        # TOML linting
cargo run --bin linter cspell      # Spell checking
cargo run --bin linter clippy      # Rust code analysis
cargo run --bin linter rustfmt     # Rust formatting check
cargo run --bin linter shellcheck  # Shell script linting

📖 See linting documentation →

🧪 Running E2E Tests

Use the E2E test binaries to run automated infrastructure tests with hardcoded environments:

# Run comprehensive E2E tests (LOCAL ONLY - connectivity issues in GitHub runners)
cargo run --bin e2e-tests-full

# Run individual E2E test suites
cargo run --bin e2e-config-tests      # Configuration generation and validation tests
cargo run --bin e2e-provision-tests   # Infrastructure provisioning tests

# Keep the test environment after completion for inspection
cargo run --bin e2e-tests-full -- --keep
cargo run --bin e2e-provision-tests -- --keep

# Use custom templates directory
cargo run --bin e2e-tests-full -- --templates-dir ./custom/templates

# See all available options
cargo run --bin e2e-tests-full -- --help

⚠️ Important Notes:

E2E tests create hardcoded environments with predefined configurations

Use --keep flag to inspect generated data/ and build/ directories after tests

e2e-tests-full can only run locally due to connectivity issues in GitHub runners

To see final OpenTofu and Ansible templates, check build/ directories after running with --keep

📖 Manual Deployment Steps (Not Currently Supported)

⚠️ Manual deployment is not currently possible. The application only supports E2E tests with hardcoded environments.

Temporary Workaround: Until the provision command is available as a user-facing command, you can use E2E tests to provision infrastructure for experimentation. See the reference section below for details.

To explore the deployment process:

Run E2E tests with --keep flag: cargo run --bin e2e-tests-full -- --keep

Inspect generated templates in build/ directories

Review environment data in data/ directories

Manual deployment commands will be available after completing the roadmap.

📋 Reference: Experimenting with OpenTofu and Ansible manually (Temporary Workaround)

Note: This is a temporary workaround for experimentation until the provision command is available as a user-facing CLI command. Currently, infrastructure provisioning is only implemented in E2E tests.

If you want to experiment with OpenTofu and Ansible commands directly using the generated templates:

1️⃣ Generate Resolved Templates

# Run E2E tests but keep the infrastructure for manual experimentation
cargo run --bin e2e-tests-full -- --keep

# This creates resolved templates (no variables) in build/ directories
# ✅ Verified: Creates build/e2e-full/tofu/lxd/ and build/e2e-full/ansible/

2️⃣ Navigate to Generated Templates

# Navigate to the specific environment's resolved OpenTofu templates
cd build/e2e-full/tofu/lxd/

# Or navigate to resolved Ansible templates
cd build/e2e-full/ansible/

# Other available environments:
# cd build/e2e-provision/tofu/lxd/
# cd build/e2e-provision/ansible/
# cd build/e2e-config/ansible/   # (config tests don't create tofu resources)

3️⃣ Execute Commands Manually

# From build/e2e-full/tofu/lxd/ - Execute OpenTofu commands
tofu plan -var-file=variables.tfvars    # ✅ Verified: Works with resolved templates
tofu validate                           # Validate configuration
tofu output -json                       # View current outputs
# Note: tofu apply already executed during E2E test

# From build/e2e-full/ansible/ - Execute Ansible commands
ansible-playbook --list-hosts -i inventory.yml wait-cloud-init.yml  # ✅ Verified: Works
ansible-playbook -i inventory.yml wait-cloud-init.yml              # Run playbook
ansible-playbook -i inventory.yml install-docker.yml               # Install Docker

4️⃣ Connect to the Instance

# Connect to the running LXD instance directly
lxc exec torrust-tracker-vm-e2e-full -- /bin/bash

# Or via SSH (IP may vary, check tofu output)
ssh -i fixtures/testing_rsa torrust@$(cd build/e2e-full/tofu/lxd && tofu output -json | jq -r '.instance_info.value.ip_address')

5️⃣ Destroy Infrastructure

# ✅ Verified: Destroy the infrastructure when done experimenting
cd build/e2e-full/tofu/lxd/
tofu destroy -var-file=variables.tfvars -auto-approve

# ✅ Verified: This removes both the VM instance and the LXD profile
# Alternative: Use LXD commands directly
# lxc delete torrust-tracker-vm-e2e-full --force
# lxc profile delete torrust-profile-e2e-full

⚠️ Important: Currently there's no application command to destroy infrastructure manually. You must use either:

OpenTofu destroy (recommended) - Uses resolved templates in build/ directories

LXD commands - Direct LXD resource management

Re-run E2E tests - Automatically destroys and recreates infrastructure

📖 For comprehensive LXD commands and examples, see LXD documentation

🎭 Infrastructure Workflow

Provision: OpenTofu creates and configures VMs with cloud-init
Configure: Ansible connects to VMs and executes management tasks
Verify: Automated checks ensure proper setup and functionality

Phase	Tool	Purpose
Infrastructure	OpenTofu	VM provisioning and cloud-init setup
Configuration	Ansible	Task execution and configuration management
Verification	Ansible Playbooks	System checks and validation

📖 See detailed Ansible documentation →

🧪 Testing in GitHub Actions

The repository includes comprehensive GitHub Actions workflows for CI testing:

.github/workflows/linting.yml - Code Quality - Runs all linters (markdown, YAML, TOML, Rust, shell scripts)
.github/workflows/testing.yml - Unit Tests - Runs Rust unit tests and basic validation
.github/workflows/test-e2e-config.yml - E2E Config Tests - Tests configuration generation and validation
.github/workflows/test-e2e-provision.yml - E2E Provision Tests - Tests infrastructure provisioning workflows
.github/workflows/test-lxd-provision.yml - LXD Provisioning - Tests LXD VM provisioning specifically

Note: The full E2E tests (e2e-tests-full) can only be executed locally due to connectivity issues documented in docs/github-actions-issues/.
