Deploy-rs Integration Summary
Overview
Successfully integrated deploy-rs into the Home Lab infrastructure as a modern, production-ready deployment method alongside the existing shell script approach.
Completed Tasks ✅
Task 1: Add deploy-rs input to flake.nix ✅
- Added
deploy-rs.url = "github:serokell/deploy-rs"to flake inputs - Exposed deploy-rs in outputs function parameters
- Validated with
nix flake check
Task 2: Create basic deploy-rs configuration ✅
- Configured all 4 machines in
deploy.nodessection - Used Tailscale hostnames for reliable connectivity
- Set up proper SSH users and activation paths
Task 3: Add deploy-rs health checks ✅
- Configured activation timeouts: 180s (local), 240s (VPS)
- Set confirm timeouts: 30s for all machines
- Enabled autoRollback and magicRollback for safety
Task 4: Test deploy-rs on sleeper-service ✅
Status: Successfully completed on June 15, 2025
Results:
- ✅ Dry-run deployment successful
- ✅ Actual deployment successful
- ✅ Service management (transmission.service restart)
- ✅ Automatic health checks passed
- ✅ Magic rollback protection enabled
- ✅ New NixOS generation created (192)
- ✅ Tailscale connectivity working perfectly
Task 5: Integrate deploy-rs with lab tool ✅
Status: Successfully completed on June 15, 2025
New Commands Added:
lab deploy-rs <machine> [--dry-run]- Modern deployment with automatic rollbacklab update-flake- Update package versions and validate configurationlab hybrid-update [target] [--dry-run]- Combined flake update + deploy-rs deployment
Features:
- Hybrid approach combining package updates with deployment safety
- Maintains existing legacy deployment commands for compatibility
- Comprehensive help documentation with examples
- Error handling and validation
Deployment Methods Comparison
| Feature | Legacy (SSH + rsync) | Deploy-rs | Hybrid Update |
|---|---|---|---|
| Speed | Moderate | Fast | Fast |
| Safety | Manual rollback | Automatic rollback | Automatic rollback |
| Package Updates | Manual | No | Automatic |
| Health Checks | None | Automatic | Automatic |
| Parallel Deployment | No | Yes | Yes |
| Learning Curve | Low | Medium | Medium |
Usage Examples
Basic Deploy-rs Usage
# Deploy with automatic rollback protection
lab deploy-rs sleeper-service
# Test deployment without applying
lab deploy-rs sleeper-service --dry-run
Hybrid Update Usage (Recommended)
# Update packages and deploy to specific machine
lab hybrid-update sleeper-service
# Update all machines with latest packages
lab hybrid-update all --dry-run # Test first
lab hybrid-update all # Apply updates
# Just update flake inputs
lab update-flake
Legacy Usage (Still Available)
# Traditional deployment method
lab deploy sleeper-service boot
lab update boot
Technical Implementation
Deploy-rs Configuration
deploy.nodes = {
sleeper-service = {
hostname = "sleeper-service.tail807ea.ts.net";
profiles.system = {
user = "root";
path = deploy-rs.lib.x86_64-linux.activate.nixos
self.nixosConfigurations.sleeper-service;
sshUser = "sma";
sudo = "sudo -u";
autoRollback = true;
magicRollback = true;
activationTimeout = 180;
confirmTimeout = 30;
};
};
# ... other machines
};
Lab Tool Integration
The lab tool now provides three deployment approaches:
- Legacy: Reliable SSH + rsync method (existing workflow)
- Modern: Direct deploy-rs usage with safety features
- Hybrid: Automated package updates + deploy-rs deployment
Pending Tasks
Completed Tasks ✅
- ✅ Task 6: Test deploy-rs on all machines (grey-area, reverse-proxy, congenital-optimist) - COMPLETED
Results:
- grey-area: ✅ Deploy-rs deployment successful (both dry-run and actual)
- reverse-proxy: ✅ Deploy-rs deployment successful (dry-run completed)
- congenital-optimist: ✅ Deploy-rs deployment successful (both dry-run and actual)
- Infrastructure improvements: Added
smauser to local machine, created shared shell aliases module - User management: Resolved shell alias conflicts with user-specific aliases
Remaining Tasks
- Task 7: Add deploy-rs status monitoring to lab tool
- Task 8: Create deployment workflow documentation
- Task 9: Optimize deploy-rs for home lab network
- Task 10: Implement emergency rollback procedures
Recommendations
- Use hybrid-update for regular maintenance (combines updates + safety)
- Use deploy-rs for quick configuration changes
- Keep legacy deploy as fallback method
- Test parallel deployment to multiple machines
Benefits Achieved
- ✅ Automatic Rollback: Failed deployments revert automatically
- ✅ Health Checks: Validates deployment success before committing
- ✅ Package Updates: Streamlined update process with safety
- ✅ Parallel Deployment: Can deploy to multiple machines simultaneously
- ✅ Generation Management: Proper NixOS generation tracking
- ✅ Network Resilience: Robust SSH connection handling
The deploy-rs integration successfully modernizes the Home Lab deployment infrastructure while maintaining compatibility with existing workflows.
