# 🔍 ArgoCD Deployment Failure Investigation - Complete
2+
3+
This PR contains a comprehensive root cause analysis for the ArgoCD deployment failure reported in **Issue #12**.
4+
5+
## 📋 What Was Done
6+
7+
✅ **Investigation Completed**
8+
- Analyzed ArgoCD configuration in `Act-3/argocd-test-app.yaml`
9+
- Cloned and inspected external repository: https://github.com/dcasati/argocd-notification-examples.git
10+
- Identified 2 critical issues causing the deployment failure
11+
- Documented detailed remediation steps with verification procedures
12+
13+
## 🎯 Root Causes Identified
14+
15+
### Issue 1: Invalid Kubernetes apiVersion (Line 178)
16+
```yaml
17+
# Current (BROKEN):
18+
apiVersion: apps/v
19+
kind: Deployment
20+
metadata:
21+
name: order-service
22+
23+
# Should be:
24+
apiVersion: apps/v1
25+
```
26+
27+
**Impact:** ArgoCD cannot sync - Kubernetes rejects the incomplete apiVersion
28+
29+
### Issue 2: Container Image Name Typo (Line 475)
30+
```yaml
31+
# Current (BROKEN):
32+
image: ghcr.io/azure-samples/aks-store-demo/store-dmin:2.1.0
33+
34+
# Should be:
35+
image: ghcr.io/azure-samples/aks-store-demo/store-admin:2.1.0
36+
```
37+
38+
**Impact:** Pod fails to start - container image doesn't exist in registry
39+
40+

74+
4. Paste as a comment

### Step 2: Fix the External Repository
77+
78+
The issues are in an external repository that this application depends on:
79+
- **Repository:** https://github.com/dcasati/argocd-notification-examples
80+
- **File:** `apps/broken-aks-store-all-in-one.yaml`
81+
82+
**Recommended Actions:**
83+
1. Contact the repository owner (@dcasati)
84+
2. Or submit a pull request with the fixes:
85+
- Line 178: `apiVersion: apps/v` → `apiVersion: apps/v1`
86+
- Line 475: `store-dmin:2.1.0` → `store-admin:2.1.0`
87+
88+
**Alternative (for immediate resolution):**
89+
- Fork the repository
90+
- Apply the fixes
91+
- Update `Act-3/argocd-test-app.yaml` to point to your fork
92+
93+
### Step 3: Verify the Fix
94+
95+
After the external repository is fixed:
96+
97+
```bash
98+
# Trigger ArgoCD sync
99+
argocd app sync 2-broken-apps
100+
101+
# Verify application health
102+
argocd app get 2-broken-apps
103+
104+
# Check pod status
105+
kubectl get pods -n default
106+
kubectl get deployment order-service -n default
107+
kubectl get deployment store-admin -n default
108+
```
109+
110+
