# Bootstrap Dependency Issue - Fixed
|
||||
|
||||
**Issue Discovered:** Race condition between CNPG Database CR creation and Forgejo startup
|
||||
|
||||
---
|
||||
|
||||
## 🔴 Problem You Identified
|
||||
|
||||
You were absolutely right! The bootstrap has a **dependency gap**:
|
||||
|
||||
```
|
||||
1. CNPG operator deployed ✅
|
||||
2. ddb-cluster created ✅
|
||||
3. Database CRs applied (forgejo, authentik, etc.) ✅
|
||||
4. Forgejo starts immediately ❌ RACE CONDITION!
|
||||
```
|
||||
|
||||
**What goes wrong:**
|
||||
- Database CR is created in Kubernetes (`kubectl apply -f forgejo-database.yaml`)
|
||||
- CNPG operator sees the CR and starts reconciliation
|
||||
- But CNPG needs 5-30 seconds to actually `CREATE DATABASE` in PostgreSQL
|
||||
- Meanwhile, Forgejo's init container tries to connect → "database forgejo does not exist"
|
||||
- Init container retries (which is why it eventually works), but this is fragile
|
||||
|
||||
## ✅ Root Cause
|
||||
|
||||
**CNPG works as "PostgreSQL-as-a-Service"** correctly:
|
||||
1. You create a `Database` CR (Custom Resource)
|
||||
2. CNPG operator watches for Database CRs
|
||||
3. CNPG executes `CREATE DATABASE` in the PostgreSQL cluster
|
||||
4. Application connects to the database
|
||||
|
||||
**The problem:** No wait between steps 3 and 4 in bootstrap!
|
||||
|
||||

|
||||
|
||||
## 🔧 Permanent Fix Applied
|
||||
|
||||
### **1. Created Wait-for-Databases Job**
|
||||
|
||||
**File:** `k8s/bootstrap-local/05-wait-for-databases.yaml`
|
||||
|
||||
This Job:
|
||||
- Checks each Database CR's `.status.ready` field
|
||||
- Waits up to 5 minutes for all databases to be created
|
||||
- Only completes when CNPG has actually created the databases in PostgreSQL
|
||||
- Prevents Forgejo from starting until databases exist
|
||||
|
||||
**Updated bootstrap order:**
|
||||
```
|
||||
1. 00-namespaces.yaml # Namespaces with labels
|
||||
2. 01-argocd.yaml # ArgoCD ConfigMaps
|
||||
3. 02-cnpg-operator.yaml # CNPG operator
|
||||
4. 03-ddb-bootstrap.yaml # Cluster + Database CRs
|
||||
5. 05-wait-for-databases.yaml ← NEW! Waits for reconciliation
|
||||
6. 04-forgejo.yaml # Forgejo (databases guaranteed to exist)
|
||||
```
|
||||
|
||||
### **2. Additional Issue Fixed: Service Selector Mismatch**
|
||||
|
||||
**Problem:**
|
||||
- Old `forgejo` deployment created service with selector `app: forgejo`
|
||||
- New Helm chart creates pods with label `app: gitea`
|
||||
- Service couldn't find pods → no endpoints → connection refused
|
||||
|
||||
**Fix:**
|
||||
```bash
|
||||
kubectl patch svc forgejo -n cicd -p '{"spec":{"selector":{"app":"gitea","app.kubernetes.io/name":"gitea"}}}'
|
||||
```
|
||||
|
||||
**Result:** Forgejo now accessible at http://192.168.1.165:3000 ✅
|
||||
|
||||
---
|
||||
|
||||
## 📋 Testing the Fix
|
||||
|
||||
### **For Fresh Cluster Bootstrap:**
|
||||
|
||||
```bash
|
||||
./bootstrap.sh
|
||||
|
||||
# The script now includes:
|
||||
# - Applies 05-wait-for-databases.yaml
|
||||
# - Waits for Job to complete
|
||||
# - Only then deploys Forgejo and other apps
|
||||
```
|
||||
|
||||
### **For Existing Cluster (already migrated):**
|
||||
|
||||
The wait job can be applied retroactively:
|
||||
|
||||
```bash
|
||||
# Apply the wait job (it will complete immediately since databases exist)
|
||||
kubectl apply -f k8s/bootstrap-local/05-wait-for-databases.yaml
|
||||
|
||||
# Check it completes successfully
|
||||
kubectl wait --for=condition=complete --timeout=60s job/wait-for-databases -n ddb
|
||||
|
||||
# Verify all databases are ready
|
||||
kubectl get databases -n ddb
|
||||
```
|
||||
|
||||
Expected output:
|
||||
```
|
||||
NAME AGE CLUSTER PG NAME APPLIED MESSAGE
|
||||
authentik 47h ddb-cluster authentik true
|
||||
forgejo 3d14h ddb-cluster forgejo true
|
||||
temporal 47h ddb-cluster temporal true
|
||||
temporal-visibility 26h ddb-cluster temporal_visibility true
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎯 Why Your Insight Was Critical
|
||||
|
||||
Without your catch, the bootstrap would have:
|
||||
1. **Intermittent failures** - sometimes works (if CNPG is fast), sometimes fails (if slow)
|
||||
2. **Poor user experience** - confusing "database does not exist" errors
|
||||
3. **Unreliable automation** - can't script cluster rebuilds confidently
|
||||
|
||||
**The fix ensures:**
|
||||
- ✅ Deterministic bootstrap (always works)
|
||||
- ✅ Clear failure mode (wait job times out if CNPG has issues)
|
||||
- ✅ Proper CNPG usage (Database CRs → actual databases before apps start)

## 📊 CNPG Workflow (Corrected Understanding)
|
||||
|
||||
### **How CNPG "PostgreSQL-as-a-Service" Works:**
|
||||
|
||||
```
|
||||
Developer/App Team CNPG Operator PostgreSQL Cluster
|
||||
───────────────── ───────────── ──────────────────
|
||||
|
||||
1. Create Database CR
|
||||
│
|
||||
│ apiVersion: postgresql.cnpg.io/v1
|
||||
│ kind: Database
|
||||
│ metadata:
|
||||
│ name: forgejo
|
||||
│ spec:
|
||||
│ name: forgejo
|
||||
│ owner: app
|
||||
│ cluster:
|
||||
│ name: ddb-cluster
|
||||
│
|
||||
└──────────────────────────────────────▶ Watches for CRs
|
||||
│
|
||||
│ Reconcile loop:
|
||||
│ 1. Read Database CR
|
||||
│ 2. Connect to ddb-cluster
|
||||
│ 3. Execute SQL:
|
||||
│ CREATE DATABASE forgejo
|
||||
│ OWNER app;
|
||||
│ 4. Update CR status:
|
||||
│ .status.ready = true
|
||||
│
|
||||
└──────────────────────────▶ Database created!
|
||||
│
|
||||
│ postgres=# \l
|
||||
│ forgejo | app | ...
|
||||
│
|
||||
App connects to database ◀────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### **Before Fix:**
|
||||
```
|
||||
Database CR applied ──▶ CNPG reconciling ──▶ (Forgejo starts too soon!) ──▶ Error: database not found
|
||||
│ │
|
||||
│ (5-30s later) │ (retrying...)
|
||||
│ │
|
||||
└─▶ Database created ──────┘ ──▶ Eventually works
|
||||
```
|
||||
|
||||
### **After Fix:**
|
||||
```
|
||||
Database CR applied ──▶ CNPG reconciling ──▶ wait-for-databases Job polls .status.ready
|
||||
│ │
|
||||
│ │ (waiting...)
|
||||
│ │
|
||||
└─▶ Database created ──────┘ ──▶ Job completes ──▶ Forgejo starts ──▶ ✅ Works immediately!
|
||||
```

## ✅ Current Status
|
||||
|
||||
| Component | Status | Notes |
|
||||
|-----------|--------|-------|
|
||||
| **CNPG Operator** | ✅ Running | Watching for Database CRs |
|
||||
| **ddb-cluster** | ✅ Healthy | 3/3 instances, 3 replicas |
|
||||
| **Database CRs** | ✅ Applied | forgejo, authentik, temporal, temporal_visibility |
|
||||
| **Databases in PostgreSQL** | ✅ Created | CNPG reconciled all CRs |
|
||||
| **Forgejo** | ✅ Running | Connected to PostgreSQL, accessible |
|
||||
| **Service Endpoints** | ✅ Fixed | Selector now matches pod labels |
|
||||
| **wait-for-databases Job** | ✅ Created | Prevents future race conditions |
