+# ArgoCD Deployment Failure Analysis: 2-broken-apps
+
+## 🔍 Root Cause Analysis
+
+I've investigated the ArgoCD deployment failure for the `2-broken-apps` application and identified **two critical issues** in the source repository that are causing the synchronization failures.
+
+### Issues Found
+
+#### 1. ❌ Invalid Kubernetes API Version (Line 178)
+**Location:** `apps/broken-aks-store-all-in-one.yaml:178`
+
+```yaml
+apiVersion: apps/v    # ❌ INVALID
+kind: Deployment
+metadata:
+  name: order-service
+```
+
+**Problem:** The `apiVersion` field is incomplete. It should be `apps/v1`, not `apps/v`.
+
+**Impact:** This causes Kubernetes to reject the manifest during validation, preventing the `order-service` Deployment from being created.
+
+---
+
+#### 2. ❌ Typo in Container Image Name (Line 475)
+**Location:** `apps/broken-aks-store-all-in-one.yaml:475`
+
+```yaml
+containers:
+  - name: store-admin
+    image: ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0  # ❌ TYPO: "store-dmin"
+```
+
+**Problem:** The image name has a typo: `store-dmin` instead of `store-admin` (missing 'a').
+
+**Impact:** The container image pull will fail with `ImagePullBackOff` error because the image `ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0` does not exist in the registry.

+
+### 🔧 Remediation Recommendations
+
+Since the source repository (`https://github.com/dcasati/argocd-notification-examples.git`) is external and appears to be intentionally broken for demonstration purposes, here are the recommended remediation steps:
+
+#### Option 1: Fork and Fix the Repository (Recommended)
+1. **Fork the repository** to your organization or personal GitHub account
+2. **Fix the two issues** in the forked repository:
+   ```bash
+   # Clone the forked repository
+   git clone https://github.com/YOUR-ORG/argocd-notification-examples.git
+   cd argocd-notification-examples
+
+   # Fix line 178: Change "apps/v" to "apps/v1"
+   sed -i '178s/apiVersion: apps\/v$/apiVersion: apps\/v1/' apps/broken-aks-store-all-in-one.yaml
+
+   # Fix line 475: Change "store-dmin" to "store-admin"
+   sed -i '475s/store-dmin/store-admin/' apps/broken-aks-store-all-in-one.yaml
+
+   # Commit and push the changes
+   git add apps/broken-aks-store-all-in-one.yaml
+   git commit -m "Fix: Correct apiVersion and image name typos"
+   git push origin main
+   ```
+
+3. **Update the ArgoCD Application manifest** (`Act-3/argocd-test-app.yaml`) to point to your forked repository:
+   ```yaml
+   spec:
+     source:
+       repoURL: https://github.com/YOUR-ORG/argocd-notification-examples.git  # Update this
+       targetRevision: main
+       path: apps
+   ```
+
+#### Option 2: Use a Local/Internal Repository
+1. Create a new directory in this repository (e.g., `Act-3/apps/`)
+2. Copy and fix the broken manifest file
+3. Update the ArgoCD Application to use a local path instead of the external repository
+
+#### Option 3: Keep as a Test Case (If Intentional)
+If this is meant to remain a broken application for testing ArgoCD notifications:
+1. Document that this is an intentional failure test case
+2. Add a label or annotation to the issue indicating this is expected behavior
+3. Consider renaming the application to make it clear it's for testing (e.g., `test-broken-apps`)
+

+
+### 📝 Verification Steps
+
+After applying the fixes, verify the deployment:
+
+```bash
+# 1. Check ArgoCD sync status
+argocd app sync 2-broken-apps
+argocd app get 2-broken-apps
+
+# 2. Verify all pods are running
+kubectl get pods -n default
+
+# 3. Check for any remaining issues
+kubectl get events -n default --sort-by='.lastTimestamp' | grep -i error
+
+# 4. Verify the deployments are healthy
+kubectl get deployments -n default
+kubectl get statefulsets -n default
+```
+

+
+### 📊 Summary
+
+| Issue | Location | Severity | Fix |
+|-------|----------|----------|-----|
+| Invalid apiVersion | Line 178 | 🔴 Critical | Change `apps/v` to `apps/v1` |
+| Image name typo | Line 475 | 🔴 Critical | Change `store-dmin` to `store-admin` |
+
+Both issues must be fixed for the application to deploy successfully. The recommended approach is to fork the repository, apply the fixes, and update the ArgoCD application to use the corrected repository.
