# Check System Dependencies Use the built-in `dependency-installer` package to verify all required tools are installed. ## Commands ```bash # Check all dependencies cargo run -p torrust-tracker-deployer-dependency-installer --bin dependency-installer check # Check a specific dependency cargo run -p torrust-tracker-deployer-dependency-installer --bin dependency-installer check --dependency opentofu # List all dependencies with status cargo run -p torrust-tracker-deployer-dependency-installer --bin dependency-installer list # Install all missing dependencies cargo run -p torrust-tracker-deployer-dependency-installer --bin dependency-installer install ``` ## Required Dependencies | Dependency | Purpose | | --------------- | ----------------------------------------- | | `opentofu` | Infrastructure provisioning (`provision`) | | `ansible` | VM configuration (`configure`, `release`) | | `lxd` | Local VM provider (LXD environments) | | `cargo-machete` | Unused dependency detection (linter / CI) | ## Exit Codes - `0` — All checked dependencies are installed - Non-zero — One or more dependencies are missing ## Interpreting Output All output goes to stderr via structured logging. Look for the summary line: ```text INFO ... All dependencies are installed ``` Or a missing dependency error: ```text ERROR ... dependency is not installed dependency="opentofu" ``` ## Notes - Run this before any `provision`, `configure`, `release`, or E2E test command - In CI/CD pipelines use `--log-level off` to suppress output and rely on exit code only: ```bash cargo run -p torrust-tracker-deployer-dependency-installer --bin dependency-installer check --log-level off ``` - To install missing tools automatically, use the `install` subcommand (requires system package manager access)
