## 🔄 Process Flow

### High-Level Flow

```
1. Setup Build Server (Ansible)
└─→ Install osbuild-composer, register with Satellite

2. Build Image (Ansible)
└─→ Upload blueprint, build disk image, download .raw file

3. Import to AWS (Ansible)
└─→ Upload to S3, import snapshot, register AMI

4. Distribute (Ansible)
└─→ Copy AMI to second region, update SSM parameters

5. Cleanup (Ansible)
└─→ Remove temporary resources
```

### CI/CD Flow

```
Developer Push
└─→ GitHub Actions (trigger)
└─→ AWS CodePipeline (orchestrate)
└─→ AWS CodeBuild (execute)
└─→ Packer (build + test)
└─→ Python scripts (wrapper)
└─→ Ansible (automation)
└─→ AMI ready for deployment
```
