## 🚀 QUICK START
|
|
|
|
### 1. Read Overview (Files to Read)
|
|

|
|
```
|
|
|
|
### 2. Review Changes
|
|
```
|
|
Read: IMPROVEMENTS.md (before/after examples)
|
|
```
|
|
|
|
### 3. Test Environment
|
|
```bash
|
|
ansible-playbook tasks/main.yml --tags preflight -vvv
|
|
```
|
|
|
|
### 4. Dry Run
|
|
```bash
|
|
ansible-playbook tasks/main.yml --check -vv
|
|
```
|
|
|
|
### 5. Deploy
|
|
```bash
|
|
ansible-playbook tasks/main.yml
|
|
```
|
|
|
|
### 6. Re-run (Test Idempotency)
|
|
```bash
|
|
ansible-playbook tasks/main.yml # Skips already-done operations!
|
|
```
|
|
|
|

|
|
|
|
## 🔍 KEY FIXES
|
|
|
|
### Fix #1: Template Conversion Now Idempotent ✅
|
|
**Problem:** Failed on re-run (broken `.lock` file logic)
|
|
**Solution:** Checks actual `template: 1` flag in VM config
|
|
**Result:** Safe to re-run!
|
|
|
|
### Fix #2: Better Error Recovery ✅
|
|
**Problem:** Tasks failed with generic errors
|
|
**Solution:** Block/rescue with context + automatic retry
|
|
**Result:** Clear messages, automatic recovery!
|
|
|
|
### Fix #3: Validation Moved to Pre-flight ✅
|
|
**Problem:** Validation errors appeared mid-playbook
|
|
**Solution:** 20+ checks run first via `preflight-checks.yml`
|
|
**Result:** Fail fast with context!
|
|
|
|
### Fix #4: Clone Errors Don't Cascade ✅
|
|
**Problem:** One failed clone stopped all clones
|
|
**Solution:** Per-clone block/rescue error handling
|
|
**Result:** One failure doesn't stop others!
|

## 🎉 HIGHLIGHTS
|
|
|
|
### Most Important Fix
|
|
**Template Conversion Bug**: Was using non-existent `.lock` file as idempotency marker. Now checks actual template status. **Huge reliability improvement!**
|
|
|
|
### Most Useful Feature
|
|
**Pre-flight Validation**: 20+ checks before execution. Fails fast with context instead of mid-playbook surprises.
|
|
|
|
### Best Practice
|
|
**Per-Clone Error Isolation**: One failed clone doesn't stop others. Much better for production deployments.
|
|
|
|
### Most Convenient
|
|
**Tag-Based Execution**: Run specific stages with `--tags clones` or `--skip-tags template`.
