### Deployment
|
||||
|
||||
ArgoCD monitors the repository and automatically syncs changes to the `demo-apps` namespace. To roll back to a previous version:
|
||||
1. Open the [ArgoCD UI](https://argocd.kyndemo.live/applications/petclinic-demo-jonathan-scaf-2).
|
||||
2. Click **History and Rollback**.
|
||||
3. Select the desired revision and click **Rollback**.
|
||||
Changes pushed to the `main` branch are automatically synced by ArgoCD to the `demo-apps` namespace. To roll back, use the ArgoCD UI or revert the Git commit.
|
||||
|
||||
Alternatively, revert the commit in Git and push — ArgoCD will auto-sync the rollback.
|
||||
### Database Setup
|
||||
|
||||
- Default: In-memory H2 database.
|
||||
- Persistent options: MySQL or PostgreSQL, configured via Spring profiles.
|
||||
|
||||
