Post-Uninstall

Uninstall post-orchestrator EMF application components.

What this does

• Removes specific EMF components
• Cleans up application deployments
• Removes databases and data

• Preserves or removes PVCs based on choice

Usage

Use this skill when you want to:

• Remove specific components
• Clean up failed deployments
• Redeploy components from scratch
• Completely remove EMF stack

---

Run post-uninstall by:

1. Confirm what to uninstall - never assume!
2. Check dependencies:
   • List components that depend on target
   • Identify services that will be affected
   • Check for active connections
3. Backup data (if needed):
   • Identify PVCs with important data
   • Backup databases
   • Export configurations
4. Preview deletion:

   cd post-orch/
   source post-orch.env
   helmfile -e onprem-eim -l app=<component> list
   

5. Execute removal:

   # Single component:
   helmfile -e onprem-eim -l app=<component> destroy
   
   # All components:
   helmfile -e onprem-eim destroy
   

6. Manual cleanup if needed:
   • Remove stuck finalizers
   • Delete PVCs: kubectl delete pvc -n <namespace> <pvc-name>
   • Clean up namespaces if needed
7. Verify cleanup:
   • Check resources are removed
   • Confirm no lingering pods/PVCs
   • Check for stuck finalizers
8. Report completion and any remaining resources

Safety checks:

• Never delete without explicit confirmation
• Warn about PVC data loss
• Check for dependent services first
• Avoid --force operations
• Be careful with namespace deletion
