feat: Implement Debian VM template creation and cloning on Proxmox
- Added default configuration for VM creation in defaults/main.yml. - Created tasks for configuring the VM with UEFI, TPM, disks, GPU, and Cloud-Init in tasks/configure-vm.yml. - Implemented clone creation and configuration logic in tasks/create-clones.yml. - Added template conversion functionality in tasks/create-template.yml. - Developed base VM creation logic in tasks/create-vm.yml. - Included image download and caching tasks in tasks/download-image.yml. - Introduced utility tasks for common operations in tasks/helpers.yml. - Organized main orchestration logic in tasks/main.yml, with clear stages for each operation. - Added pre-flight checks to validate the environment before execution in tasks/preflight-checks.yml.

|
||||
## 🚀 Key Achievements
|
||||
|
||||
### ✅ Error Handling
|
||||
```yaml
|
||||
# Automatic retry logic
|
||||
retries: 3
|
||||
delay: 5
|
||||
until: result is succeeded
|
||||
|
||||
# Context-aware error messages
|
||||
fail:
|
||||
msg: "Clear error + what to do next"
|
||||
```
|
||||
|
||||
### ✅ Idempotency (Critical Fix!)
|
||||
**Fixed:** Template conversion was broken!
|
||||
- **Before:** Used non-existent `.lock` file → always failed on re-run
|
||||
- **After:** Checks actual `template: 1` flag → truly idempotent
|
||||
|
||||
### ✅ Pre-flight Validation
|
||||
Validates before execution:
|
||||
- Proxmox installed & accessible
|
||||
- Storage pool exists
|
||||
- SSH keys available
|
||||
- IP addresses valid
|
||||
- Permissions correct
|
||||
- VM IDs unique
|
||||
- ... 14 more checks!
|
||||
|
||||
### ✅ Modular Design
|
||||
6 independent, testable, reusable task files
|
||||
|
||||
### ✅ Enhanced Logging
|
||||
Rich progress tracking with stage markers:
|
||||
```
|
||||
[PREFLIGHT] Checking environment...
|
||||
[IMAGE] Downloading Debian...
|
||||
[VM] Creating virtual machine...
|
||||
[CONFIG] Configuring disk...
|
||||
[TEMPLATE] Converting to template...
|
||||
[CLONES] Deploying clones...
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 💡 Usage Examples
|
||||
|
||||
### Full Deployment
|
||||
```bash
|
||||
ansible-playbook tasks/main.yml -i inventory
|
||||
```
|
||||
|
||||
### Safe Re-run (Idempotent)
|
||||
```bash
|
||||
# Same command - skips already-completed operations
|
||||
ansible-playbook tasks/main.yml -i inventory
|
||||
```
|
||||
|
||||
### Specific Stages
|
||||
```bash
|
||||
# Pre-flight checks only
|
||||
ansible-playbook tasks/main.yml --tags preflight
|
||||
|
||||
# Clone creation only
|
||||
ansible-playbook tasks/main.yml --tags clones
|
||||
|
||||
# Skip template conversion
|
||||
ansible-playbook tasks/main.yml --skip-tags template
|
||||
```
|
||||
|
||||
### Dry Run (No Changes)
|
||||
```bash
|
||||
ansible-playbook tasks/main.yml --check -vv
|
||||
```
