ArgoCD deployment failure analysis: 2-broken-apps root cause identified

[Copilot]

Analyzed ArgoCD sync failure for 2-broken-apps application. Root cause traced to malformed manifests in the external source repository (dcasati/argocd-notification-examples.git@8cd04df).

Root Causes

Invalid Kubernetes API version (Line 178, order-service Deployment):

apiVersion: apps/v  # Missing '1' suffix
kind: Deployment

Container image name typo (Line 475, store-admin Deployment):

image: ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0  # Should be "store-admin"

Context

Errors were intentionally introduced per commit message: "break apiVersion formatting in deployment YAML". This validates the ArgoCD notification pipeline is functioning correctly:

• Sync failures detected ✓
• Notifications triggered ✓
• GitHub issues auto-created ✓

Remediation Options

1. Fix source repository - Correct the apiVersion and image name in apps/broken-aks-store-all-in-one.yaml
2. Point to different repo - Update Act-3/argocd-test-app.yaml with working manifest source
3. Accept test behavior - Current state validates monitoring infrastructure

Full analysis available in GitHub Actions step summary and output artifacts.

Note: No code changes made to this repository per task instructions (analysis only).
