## 🚀 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
|
|
```
