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 Improvements
|
||||
|
||||
### 1. Error Handling ✅
|
||||
**Before:** Tasks fail with generic errors
|
||||
**After:** Try-catch blocks with context-aware messages and automatic retry
|
||||
|
||||
```yaml
|
||||
# Now all operations have:
|
||||
block:
|
||||
- name: "Try operation"
|
||||
command: ...
|
||||
retries: 3
|
||||
delay: 5
|
||||
until: result is succeeded
|
||||
rescue:
|
||||
- name: "Handle with context"
|
||||
fail:
|
||||
msg: "Clear error + next steps"
|
||||
```
|
||||
|
||||
### 2. Idempotency ✅
|
||||
**Before:** Fails on re-run (template conversion broken!)
|
||||
**After:** Safe to run 10 times - already-completed operations are skipped
|
||||
|
||||
```yaml
|
||||
# Now every operation checks first:
|
||||
- stat: path="/etc/pve/qemu-server/{{ vm_id }}.conf"
|
||||
register: vm_exists
|
||||
- command: "create VM"
|
||||
when: not vm_exists.stat.exists
|
||||
```
|
||||
|
||||
### 3. Pre-flight Validation ✅
|
||||
**Before:** No checks - fails mid-playbook
|
||||
**After:** 20+ validations before starting
|
||||
|
||||
```bash
|
||||
✓ Proxmox installed
|
||||
✓ qm command available
|
||||
✓ Storage pool exists
|
||||
✓ SSH key accessible
|
||||
✓ IP addresses valid
|
||||
✓ VM IDs unique
|
||||
... and more!
|
||||
```
|
||||
|
||||
### 4. Modular Design ✅
|
||||
**Before:** 150+ lines in one file
|
||||
**After:** 6 focused, reusable task files
|
||||
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| preflight-checks.yml | Validate environment (20+ checks) |
|
||||
| download-image.yml | Get image with caching |
|
||||
| create-vm.yml | Create VM (idempotent) |
|
||||
| configure-vm.yml | Configure VM (disk, network, Cloud-Init) |
|
||||
| create-template.yml | Convert to template (fixed!) |
|
||||
| create-clones.yml | Deploy clones (per-clone error handling) |
|
||||
|
||||
### 5. Fixed Template Conversion Bug ✅
|
||||
**Before:** Failed on re-run because it used non-existent `.lock` file
|
||||
**After:** Checks actual template flag - truly idempotent!
|
||||
|
||||
```yaml
|
||||
# Was using broken creates: /etc/pve/qemu-server/{{ vm_id }}.conf.lock
|
||||
# Now checks: grep 'template: 1' qm config
|
||||
# Result: ✓ Safe to re-run!
|
||||
```
|
||||

|
||||
|
||||
## How to Use
|
||||
|
||||
### ✨ Full Deployment
|
||||
```bash
|
||||
ansible-playbook tasks/main.yml -i inventory
|
||||
```
|
||||
Runs all stages: validation → image → VM → config → template → clones
|
||||
|
||||
### 🔄 Safe Re-run (Idempotent)
|
||||
```bash
|
||||
# Same command, second time
|
||||
ansible-playbook tasks/main.yml -i inventory
|
||||
```
|
||||
Skips already-done operations (much faster!)
|
||||
|
||||
### 🎯 Specific Stages
|
||||
```bash
|
||||
# Validate environment only
|
||||
ansible-playbook tasks/main.yml --tags preflight
|
||||
|
||||
# Clone creation only
|
||||
ansible-playbook tasks/main.yml --tags clones
|
||||
|
||||
# Everything except template
|
||||
ansible-playbook tasks/main.yml --skip-tags template
|
||||
```
|
||||
|
||||
### 🧪 Dry Run (No Changes)
|
||||
```bash
|
||||
ansible-playbook tasks/main.yml --check -vv
|
||||
```
|
||||
|
||||
### 🔍 Debug Output
|
||||
```bash
|
||||
ansible-playbook tasks/main.yml -vvv
|
||||
```
