check-system-dependencies
Check whether the system has all dependencies required by the deployer (OpenTofu, Ansible, LXD, cargo-machete). Use before running provisioning, E2E tests, or any infrastructure command. Triggers on "check dependencies", "check system dependencies", "are dependencies installed", "verify dependencies", "dependency check", or "missing tools".

# 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)
