Use for previewing templates, manual deployment, validating configurations, and verifying template changes. Enables fast create→render workflow for contributors to verify template modifications without full deployment. Triggers on "render", "generate artifacts", "preview deployment", "verify templates", "manual deployment", or "check template changes". +metadata: + author: torrust + version: "1.0" +--- + +# Render Tracker Artifacts + +This skill helps you generate deployment artifacts for the Torrust Tracker without provisioning infrastructure. + +## When to Use This Skill + +Use this skill when you need to: + +### For Manual Deployment + +- **Generate artifacts for manual deployment** - Create deployment files to use with external tools +- **Preview deployment configuration** - Inspect what will be deployed before provisioning +- **Deploy to existing infrastructure** - Use generated artifacts with pre-existing servers +- **Custom deployment workflows** - Integrate generated artifacts into your own automation + +### For Contributors and Template Development + +- **Verify template changes quickly** - Test template modifications without full deployment +- **Fast development iteration** - Use `create → render` instead of slow `create → provision → configure` +- **Template validation** - Ensure templates render correctly with different configurations +- **Compare configurations** - Generate artifacts for multiple setups to compare differences + +### For Validation and Inspection + +- **Configuration validation** - Verify config files produce valid artifacts +- **Troubleshooting** - Inspect generated files to diagnose deployment issues +- **Documentation** - Generate example artifacts for documentation purposes +- **Security review** - Review generated configurations before deployment + +## How Render Works + +The render command generates **all deployment artifacts** without creating infrastructure: + +```text +Configuration → Template Rendering → Artifacts (No Infrastructure) +``` + +**Generated Artifacts:** + +- **OpenTofu** - Infrastructure as code definitions +- **Ansible** - Playbooks and inventory files +- **Docker Compose** - Service orchestration configuration +- **Tracker** - Tracker configuration (tracker.toml) +- **Prometheus** - Monitoring configuration +- **Grafana** - Dashboard provisioning +- **Caddy** - Reverse proxy configuration (if HTTPS enabled) +- **Backup** - Backup scripts (if backup enabled) + +## Prerequisites + +### Required Tools + +- None (render is a read-only operation requiring no external tools) + +### Input Requirements + +**Choose one input mode:** + +1. **Existing environment** (Created state): + - Environment must exist in `data/{env-name}/` + - Configuration must be valid + +2. **Configuration file** (no environment needed): + - Valid JSON configuration file + - See `schemas/environment-config.json` for schema + +### Output Requirements + +- **Output directory must not exist** (or use `--force` to overwrite) +- **Write permissions** to output directory location +- **Instance IP address** required (IPv4 or IPv6) + +## Command Syntax + +### From Existing Environment + +```bash +torrust-tracker-deployer render \ + --env-name \ + --instance-ip \ + --output-dir +``` + +### From Configuration File + +```bash +torrust-tracker-deployer render \ + --env-file \ + --instance-ip \ + --output-dir +``` + +### With Force Overwrite + +```bash +torrust-tracker-deployer render \ + --env-name \ + --instance-ip \ + --output-dir \ + --force +``` + +## Common Workflows + +### Workflow 1: Preview Before Provisioning + +**Scenario**: You want to see what artifacts will be generated before committing to infrastructure provisioning. + +```bash +# Step 1: Create environment (no infrastructure created) +torrust-tracker-deployer create environment -f envs/my-config.json + +# Step 2: Preview artifacts with test IP +torrust-tracker-deployer render \ + --env-name my-env \ + --instance-ip 192.168.1.100 \ + --output-dir ./preview-my-env + +# Step 3: Inspect generated artifacts +ls -la preview-my-env/ +cat preview-my-env/ansible/inventory.ini +cat preview-my-env/docker-compose/docker-compose.yml +cat preview-my-env/tracker/tracker.toml + +# Step 4: If satisfied, provision for real +torrust-tracker-deployer provision my-env +``` + +### Workflow 2: Verify Template Changes (Contributors) + +**Scenario**: You've modified templates and want to verify they render correctly without going through the slow deployment process. + +```bash +# Step 1: Create test environment +torrust-tracker-deployer create environment -f envs/lxd-local-example.json + +# Step 2: Render artifacts to verify template changes +torrust-tracker-deployer render \ + --env-name lxd-local-example \ + --instance-ip 10.0.0.100 \ + --output-dir ./template-test + +# Step 3: Check the specific template you modified +cat template-test/ansible/playbooks/your-playbook.yml +cat template-test/docker-compose/docker-compose.yml + +# Step 4: Make template changes and re-render +# Edit templates in templates/ directory +torrust-tracker-deployer render \ + --env-name lxd-local-example \ + --instance-ip 10.0.0.100 \ + --output-dir ./template-test \ + --force + +# Step 5: Verify changes +diff -u /tmp/old-render/ansible/playbooks/your-playbook.yml \ + template-test/ansible/playbooks/your-playbook.yml +``` + +**Why This Is Fast:** + +- ✅ **No infrastructure provisioning** (skips LXD VM creation, cloud API calls) +- ✅ **No remote operations** (skips SSH, Ansible execution) +- ✅ **Instant feedback** (only template rendering, ~1-2 seconds) +- ✅ **Repeatable** (use `--force` to regenerate instantly) + +**Comparison:** + +```text +Full Deployment: create → provision (~5 min) → configure (~3 min) → release (~2 min) +Template Verify: create → render (~2 sec) → inspect → modify → render (~2 sec) + +Time saved: ~10 minutes per iteration +``` + +### Workflow 3: Generate from Config File (No Environment) + +**Scenario**: You want to generate artifacts directly from a configuration file without creating a persistent environment. + +```bash +# Generate artifacts directly from config file +torrust-tracker-deployer render \ + --env-file envs/production.json \ + --instance-ip 10.0.0.5 \ + --output-dir /tmp/production-artifacts + +# Inspect artifacts (no environment created in data/) +ls -la /tmp/production-artifacts/ +cat /tmp/production-artifacts/docker-compose/docker-compose.yml + +# Use artifacts with external deployment tools +scp -r /tmp/production-artifacts/ user@target-host:/opt/deployment/ +``` + +### Workflow 4: Compare Multiple Configurations + +**Scenario**: You want to compare artifacts generated with different IPs or configurations. + +```bash +# Render with different IPs +torrust-tracker-deployer render \ + --env-name my-env \ + --instance-ip 192.168.1.10 \ + --output-dir ./preview-ip-10 + +torrust-tracker-deployer render \ + --env-name my-env \ + --instance-ip 10.0.1.20 \ + --output-dir ./preview-ip-20 + +# Compare artifacts +diff -r preview-ip-10/ preview-ip-20/ +diff -u preview-ip-10/ansible/inventory.ini \ + preview-ip-20/ansible/inventory.ini +``` + +### Workflow 5: Template Development with E2E Verification + +**Scenario**: You're developing templates and want to verify they work end-to-end with the deployment workflow. + +```bash +# Step 1: Create environment +torrust-tracker-deployer create environment -f envs/lxd-local-example.json + +# Step 2: Quick render to verify syntax +torrust-tracker-deployer render \ + --env-name lxd-local-example \ + --instance-ip 10.0.0.100 \ + --output-dir ./quick-check + +# Step 3: Inspect for obvious errors +cat quick-check/ansible/playbooks/your-new-playbook.yml +yamllint quick-check/ansible/playbooks/your-new-playbook.yml + +# Step 4: If templates look good, test with real deployment +torrust-tracker-deployer provision lxd-local-example +torrust-tracker-deployer configure lxd-local-example +# ... continue full workflow +``` + +### Workflow 6: Manual Deployment with Rendered Artifacts + +**Scenario**: You want to deploy manually using the generated artifacts. + +```bash +# Step 1: Generate artifacts for your target +torrust-tracker-deployer render \ + --env-file envs/production.json \ + --instance-ip 203.0.113.50 \ + --output-dir ./manual-deploy + +# Step 2: Copy artifacts to target server +scp -r ./manual-deploy/ admin@203.0.113.50:/tmp/deploy/ + +# Step 3: Execute deployment manually on target +ssh admin@203.0.113.50 +cd /tmp/deploy/ + +# Run Ansible playbooks manually +ansible-playbook -i ansible/inventory.ini ansible/playbooks/*.yml + +# Or manually execute Docker Compose +docker compose -f docker-compose/docker-compose.yml up -d +``` + +## Understanding Output Directory Requirement + +**Why `--output-dir` is required:** + +1. **Prevents conflicts** - Avoids overwriting `build/{env}/` used by provision command +2. **Enables preview** - Generate artifacts without affecting deployment state +3. **Allows multiple renders** - Create artifacts with different IPs/configs simultaneously +4. **Clear separation** - Distinguishes preview (render) from deployment (provision) + +**Output directory structure:** + +```text +/ +├── opentofu/ # Infrastructure code +├── ansible/ # Configuration playbooks +│ ├── inventory.ini # Instance IP configured here +│ ├── ansible.cfg +│ └── playbooks/ +├── docker-compose/ # Service definitions +│ ├── docker-compose.yml +│ └── .env +├── tracker/ # Tracker configuration +│ └── tracker.toml +├── prometheus/ # Monitoring +│ └── prometheus.yml +├── grafana/ # Dashboards +│ └── provisioning/ +├── caddy/ # Reverse proxy (if HTTPS) +│ └── Caddyfile +└── backup/ # Backup scripts (if enabled) + └── backup.sh +``` + +## Tips and Best Practices + +### For Contributors + +1. **Use render for template iteration** - Much faster than full deployment workflow +2. **Test with real config** - Use actual environment configs from `envs/` directory +3. **Verify all artifact types** - Check not just the template you modified but all dependent files +4. **Use force flag** - `--force` for quick iteration without manual deletion +5. **Compare before/after** - Keep old renders to diff against new changes + +### For Manual Deployment + +1. **Version your renders** - Name output directories with timestamps or versions +2. **Document instance IP** - Record which IP was used for artifact generation +3. **Verify before deploy** - Always inspect critical files (inventory, docker-compose, tracker.toml) +4. **Test in staging** - Render for staging environment first, test, then render for production + +### For Validation + +1. **Render with multiple IPs** - Ensure artifacts work with different network configurations +2. **Check file permissions** - Verify generated files have correct permissions +3. **Validate syntax** - Use linters on generated YAML/TOML files +4. **Inspect secrets** - Ensure API tokens and passwords are correctly populated + +### Performance Tips + +1. **Render is fast** (~1-2 seconds) - Use it liberally for verification +2. **Use `--force`** - Faster than manually deleting output directories +3. **Keep renders small** - Delete old preview directories when done +4. **Parallel renders** - Can render multiple configs simultaneously to different output dirs + +## Error Handling + +### Common Errors and Solutions + +#### Error: Output directory already exists + +```text +Error: Output directory already exists: ./preview +``` + +**Solution**: Use `--force` flag or delete the directory: + +```bash +# Option 1: Use force +torrust-tracker-deployer render --env-name my-env --instance-ip 10.0.0.1 --output-dir ./preview --force + +# Option 2: Delete manually +rm -rf ./preview +torrust-tracker-deployer render --env-name my-env --instance-ip 10.0.0.1 --output-dir ./preview +``` + +#### Error: Environment not found + +```text +Error: Environment 'my-env' not found in Created state +``` + +**Solution**: Create environment first or use `--env-file`: + +```bash +# Option 1: Create environment +torrust-tracker-deployer create environment -f envs/my-config.json + +# Option 2: Use config file directly +torrust-tracker-deployer render --env-file envs/my-config.json --instance-ip 10.0.0.1 --output-dir ./preview +``` + +#### Error: Invalid IP address + +```text +Error: Invalid IP address: '999.999.999.999' +``` + +**Solution**: Provide valid IPv4 or IPv6 address: + +```bash +# Valid IPv4 +torrust-tracker-deployer render --env-name my-env --instance-ip 192.168.1.100 --output-dir ./preview + +# Valid IPv6 +torrust-tracker-deployer render --env-name my-env --instance-ip 2001:db8::1 --output-dir ./preview +``` + +#### Error: Configuration file not found + +```text +Error: Configuration file not found: envs/missing.json +``` + +**Solution**: Check file path and existence: + +```bash +# List available configs +ls -la envs/ + +# Use correct path +torrust-tracker-deployer

Command Handler (2-3 hours) - -- [ ] Create `src/application/command_handlers/render/mod.rs` -- [ ] Create `RenderCommandHandler` struct -- [ ] Define `RenderInput` (environment name OR config file path + IP, plus output directory) -- [ ] Define `RenderOutput` (output directory path + target IP) -- [ ] Define `RenderCommandHandlerError` enum -- [ ] Implement dual input modes: - - [ ] From environment data (IP extracted from infrastructure outputs) - - [ ] From config file + explicit IP parameter -- [ ] Add IP address validation -- [ ] Add comprehensive error messages with actionable instructions -- [ ] Add unit tests for command handler logic - -### Phase 2: Template Orchestration (3-4 hours) - -- [ ] Identify all existing template renderers: - - [ ] `TofuTemplateRenderer` (infrastructure) - - [ ] `AnsibleProjectGenerator` (configuration) - - [ ] `DockerComposeRenderer` (application stack) - - [ ] Tracker config renderer (from release command) - - [ ] Monitoring config renderers (Prometheus/Grafana) - - [ ] Caddy config renderer - - [ ] Backup config renderer -- [ ] Create orchestration logic to invoke ALL renderers (no conditional logic) -- [ ] Ensure all artifacts write to user-specified output directory subdirectories -- [ ] Pass IP address to Ansible inventory template renderer -- [ ] Add progress indicators using `UserOutput` -- [ ] Add integration tests verifying all templates rendered with correct IP - -### Phase 3: Presentation Layer - CLI Command (2 hours) - -- [ ] Create `src/presentation/controllers/render/mod.rs` -- [ ] Create `RenderCommandController` -- [ ] Add CLI argument parsing: - - [ ] `--env-name ` (mutually exclusive with `--env-file`) - - [ ] `--env-file ` (mutually exclusive with `--env-name`, requires `--ip`) - - [ ] `--ip ` (required when using `--env-file`, forbidden with `--env-name`) - - [ ] `--output-dir ` (REQUIRED always) - - [ ] `--force` (optional, overwrites existing output directory) -- [ ] Implement input validation: - - [ ] Ensure `--env-name` and `--env-file` are mutually exclusive - - [ ] Ensure `--ip` is present when using `--env-file` - - [ ] Ensure `--ip` is NOT present when using `--env-name` (would be confusing) - - [ ] Validate IP address format - - [ ] Ensure `--output-dir` is always provided -- [ ] Connect to `RenderCommandHandler` -- [ ] Format output using `UserOutput` (progress, success, output directory path, target IP) -- [ ] Handle errors with clear messages -- [ ] Add help text and examples -- [ ] Add unit tests for controller logic - -### Phase 4: Documentation and Testing (2-3 hours) - -- [ ] Create user guide: `docs/user-guide/commands/render.md` - - [ ] Overview and use cases - - [ ] Command syntax and options - - [ ] Examples for common scenarios - - [ ] Explanation of generated artifacts - - [ ] Integration with manual deployment workflow -- [ ] Update `docs/console-commands.md` with render command -- [ ] Update roadmap (`docs/roadmap.md`) - mark task 9.2 complete -- [ ] Add E2E tests: - - [ ] Generate from existing environment (with `--env-name`) - - [ ] Generate from config file (with `--env-file` + `--ip`) - - [ ] Verify all expected files created - - [ ] Verify output directory structure - - [ ] Verify Ansible inventory contains correct IP address - - [ ] Test error conditions: - - [ ] Missing `--output-dir` - - [ ] Missing `--ip` when using `--env-file` - - [ ] Invalid IP format - - [ ] Missing environment - - [ ] Invalid config - - [ ] Test `--force` flag (overwrite existing output directory) -- [ ] Run pre-commit checks: `./scripts/pre-commit.sh` - -### Phase 5: Polish and Review (1-2 hours) +**Approach**: Outside-In Development (Presentation → Application → Infrastructure) + +Following `.github/skills/add-new-command/skill.md` for testability at each phase. + +### Phase 0: Template Rendering Services Refactor (PREREQUISITE) ✅ COMPLETED + +**Goal**: Extract reusable template rendering services to enable clean render command implementation. + +**Status**: ✅ Completed -
