# CHANGELOG
## Version 2.0 - Production-Grade Improvements (2025-11-15)
### Major Changes
#### 1. Architecture Refactoring
- **ADDED**: Split `tasks/main.yml` into 6 modular task files
- **ADDED**: `tasks/preflight-checks.yml` - Environment validation
- **ADDED**: `tasks/download-image.yml` - Debian image with caching
- **ADDED**: `tasks/create-vm.yml` - Idempotent VM creation
- **ADDED**: `tasks/configure-vm.yml` - Disk, Cloud-Init, TPM, GPU
- **ADDED**: `tasks/create-template.yml` - Idempotent template conversion
- **ADDED**: `tasks/create-clones.yml` - Clone deployment with per-clone error handling
- **CHANGED**: `tasks/main.yml` now orchestrates subtasks via `include_tasks`
- **BENEFIT**: Each stage is independent, testable, and reusable
#### 2. Error Handling
- **ADDED**: Block/rescue error handling to all major operations
- **ADDED**: Automatic retry logic (3 retries, 5-second delays)
- **ADDED**: Context-aware error messages with next steps
- **ADDED**: Validation checks before operations
- **BENEFIT**: Clear failures with guidance, not silent errors
#### 3. Idempotency
- **ADDED**: Status checks before all state-changing operations
- **FIXED**: Template conversion (was broken on re-run)
- Before: Used non-existent `.lock` file as idempotency marker
- After: Checks actual `template: 1` flag in VM config
- **ADDED**: VM existence check before creation
- **ADDED**: Clone existence check before cloning
- **ADDED**: Image existence check before download
- **BENEFIT**: Safe to re-run playbook multiple times
#### 4. Pre-flight Validation
- **ADDED**: Comprehensive pre-flight checks (20+ validations)
- Proxmox installation and version
- User permissions for `qm` commands
- Storage pool existence and accessibility
- SSH key file existence and readability
- VM ID uniqueness and format
- Clone ID uniqueness and format
- IP address format validation (CIDR)
- Gateway IP validation
- DNS server IP validation
- Snippets directory existence
- **BENEFIT**: Fail fast with clear messages, not 50% through playbook
#### 5. Configuration Improvements
- **IMPROVED**: `defaults/main.yml` with extensive documentation
- **ADDED**: Retry and timeout configuration variables
- **ADDED**: Debug mode option
- **ADDED**: Security warnings and Vault integration example
- **CHANGED**: Better-organized variable sections with headers
- **BENEFIT**: Clear, maintainable configuration
#### 6. Task Enhancements
##### download-image.yml
- **ADDED**: Caching (skips re-download if exists)
- **ADDED**: Directory creation if missing
- **ADDED**: Automatic retry on download failure
- **ADDED**: Image integrity verification (size check)
- **ADDED**: Image info display (size, date)
##### create-vm.yml
- **ADDED**: VM existence check
- **ADDED**: Error handling with meaningful messages
- **ADDED**: Verification after creation
- **ADDED**: Status messages before and after
##### configure-vm.yml
- **ADDED**: Block/rescue for disk configuration
- **ADDED**: SSH key validation before use
- **ADDED**: Retry logic for disk import
- **ADDED**: Cloud-Init snippet validation
- **ADDED**: Separate blocks for TPM, disk, GPU configs
- **IMPROVED**: Better error recovery
##### create-template.yml
- **FIXED**: Idempotent template conversion (major fix!)
- **ADDED**: VM stop verification before conversion
- **ADDED**: Template status check
- **ADDED**: Proper error handling
- **CHANGED**: Skip if already templated
##### create-clones.yml
- **ADDED**: Per-clone error handling (loop with block/rescue)
- **ADDED**: Clone existence check
- **ADDED**: Clone list validation
- **ADDED**: Individual clone result reporting
- **BENEFIT**: One failed clone doesn't stop others
#### 7. Cloud-Init Improvements
- **ADDED**: SSH key readability check
- **ADDED**: Snippet file validation
- **IMPROVED**: Cloud-Init configuration application
- **BENEFIT**: Clear errors if configuration fails
#### 8. Helper Utilities
- **ADDED**: `tasks/helpers.yml` with reusable functions
- `check_vm_exists` - Check if VM exists
- `check_template` - Check if VM is template
- `check_vm_status` - Get VM status
- `check_storage` - Check storage space
- `validate_vm_id` - Validate VM ID format
- `get_vm_info` - Read VM configuration
- `list_vms` - List all VMs
- `cleanup_snippets` - Remove old snippets
- **BENEFIT**: Reusable functions for automation
#### 9. Logging & Visibility
- **ADDED**: Task naming convention `[STAGE] Action: description`
- **ADDED**: Progress banner at playbook start
- **ADDED**: Completion summary at playbook end
- **ADDED**: Per-operation status messages
- **ADDED**: Rich debug output throughout
- **BENEFIT**: Clear visibility into what's happening
#### 10. Documentation
- **ADDED**: `IMPROVEMENTS.md` - Detailed guide with before/after
- **ADDED**: `QUICK_REFERENCE.md` - Commands and troubleshooting
- **ADDED**: `IMPLEMENTATION_SUMMARY.md` - Overview and manifest
- **ADDED**: `CHANGELOG.md` - This file
- **ADDED**: Extensive inline comments in all task files
- **IMPROVED**: `defaults/main.yml` comments and structure
### Backward Compatibility
⚠️ **Breaking Changes**: None - role is backward compatible
- Old `create_clones` and `make_template` variables still work
- Old task structure wrapped in new modular approach
- All existing variables are preserved
- Default values unchanged
### Migration
1. Replace task files with new versions
2. Update `defaults/main.yml` (new options are optional)
3. Run `--tags preflight -vvv` to verify environment
4. Test with `--check` flag
5. Run normally
### Known Issues Fixed
| Issue | Before | After |
|-------|--------|-------|
| Template conversion fails on re-run | ❌ Broken | ✅ Idempotent |
| No validation of SSH key | ❌ Silent failure | ✅ Checked before use |
| One failed clone stops all clones | ❌ All-or-nothing | ✅ Per-clone handling |
| Poor error messages | ❌ Generic errors | ✅ Context-aware |
| No pre-flight validation | ❌ Fails mid-playbook | ✅ Early validation |
| Can't re-run playbook safely | ❌ Fails or duplicates | ✅ Idempotent |
### Performance Improvements
- **Image caching**: No re-download if already present
- **Selective execution**: Use tags to skip expensive operations
- **Retry logic**: Automatic recovery without manual intervention
### Testing Recommendations
```bash
# 1. Validate environment
ansible-playbook tasks/main.yml --tags preflight -vvv
# 2. Dry run
ansible-playbook tasks/main.yml --check -vv
# 3. Full test
ansible-playbook tasks/main.yml -vv
# 4. Verify idempotency (re-run)
ansible-playbook tasks/main.yml -vv
# 5. Add clones only
ansible-playbook tasks/main.yml --tags clones -vv
```
### Configuration Examples Added
- Minimal DHCP setup
- Production static IP setup
- TPM + Vault integration
- Multi-clone scenarios
### Security Enhancements
- SSH key validation before use
- Permissions checking for `qm` command
- Ansible Vault integration example
- Clear security warnings in comments
