|
|
**Production Readiness**: ⚠️ Not ready - 5 critical issues must be resolved
|
|
**Estimated Timeline**: 4-6 weeks to address critical and high-priority issues
|
|
|
|

|
|
|
|
## Critical Issues (Must Fix - Week 1)
|
|
|
|
### 1. Genesis ExtraData Generation 🔴
|
|
|
|
**Problem**: Genesis file has empty `extraData: "0x"` which will prevent QBFT 2.0 network from starting.
|
|
|
|
**Current State**:
|
|
```json
|
|
"extraData": "0x"
|
|
```
|
|
|
|
**Required State**: Proper RLP-encoded validator list
|
|
|
|
**Solution**:
|
|
- ✅ Created `scripts/generate-genesis-proper.sh`
|
|
- Uses Besu's `operator generate-blockchain-config`
|
|
- Generates proper QBFT extraData with validator addresses
|
|
|
|
**Action**:
|
|
```bash
|
|
./scripts/generate-genesis-proper.sh 4
|
|
# Verify: jq '.extraData' config/genesis.json
|
|
```
|
|
|
|
**Files**: `config/genesis.json`, `scripts/generate-genesis.sh`
|
|
|
|
---
|
|
|
|
### 2. Image Version Pinning 🔴
|
|
|
|
**Problem**: 8+ deployments use `:latest` tag causing unpredictable deployments.
|
|
|
|
**Current State**:
|
|
- `hyperledger/besu:latest`
|
|
- `blockscout/blockscout:latest`
|
|
- `prom/prometheus:latest`
|
|
- `busybox:latest`
|
|
|
|
**Solution**:
|
|
- ✅ Created `scripts/fix-image-versions.sh`
|
|
- Pins versions: Besu 23.10.0, Blockscout v5.1.5, Prometheus v2.45.0
|
|
|
|
**Action**:
|
|
```bash
|
|
./scripts/fix-image-versions.sh
|
|
# Verify: grep -r "latest" k8s/ helm/ monitoring/
|
|
```
|
|
|
|
**Files**: All Kubernetes and Helm deployment files
|
|
|
|
---
|
|
|
|
### 3. Hardcoded Secrets 🔴
|
|
|
|
**Problem**: Placeholder passwords in deployment files (`"change-me-in-production"`).
|
|
|
|
**Current State**:
|
|
```yaml
|
|
stringData:
|
|
secret_key_base: "change-me-in-production"
|
|
postgres_password: "change-me-in-production"
|
|
```
|
|
|
|
**Solution**:
|
|
- ✅ Created `scripts/generate-secrets.sh`
|
|
- Generates secure secrets using OpenSSL
|
|
- Creates Kubernetes Secrets
|
|
|
|
**Action**:
|
|
```bash
|
|
./scripts/generate-secrets.sh
|
|
# Verify: kubectl get secrets -n besu-network
|
|
```
|
|
|
|
**Files**: `k8s/blockscout/deployment.yaml`
|
|
|
|
---
|
|
|
|
### 4. Application Gateway Configuration 🔴
|
|
|
|
**Problem**: Application Gateway is placeholder - missing backend pools, listeners, and routing rules.
|
|
|
|
**Current State**: Basic structure only, no backend configuration
|
|
|
|
**Solution**:
|
|
- ✅ Created `terraform/modules/networking/appgateway-complete.tf` as reference
|
|
- Complete configuration needed in `terraform/modules/networking/main.tf`
|
|
- Or consider using Azure Application Gateway Ingress Controller (AGIC)
|
|
|
|
**Action**:
|
|
- Complete Application Gateway configuration
|
|
- Configure backend pools for RPC nodes
|
|
- Set up HTTP/HTTPS listeners
|
|
- Configure SSL certificates
|
|
- Add health probes
|
|
|
|
**Files**: `terraform/modules/networking/main.tf`
|
|
|
|
---
|
|
|
|
### 5. Health Check Endpoints 🔴
|
|
|
|
**Problem**: Health checks use `/liveness` and `/readiness` endpoints that may not exist in Besu.
|
|
|
|
**Current State**:
|
|
```yaml
|
|
livenessProbe:
|
|
httpGet:
|
|
path: /liveness
|
|
port: metrics
|
|
```
|
|
|
|
**Solution**:
|
|
- Use `/metrics` endpoint instead
|
|
- Or implement custom health check script
|
|
- Verify Besu actually exposes these endpoints
|
|
|
|
**Action**:
|
|
- Verify Besu health check endpoints
|
|
- Update all StatefulSet files
|
|
- Test health checks in deployed environment
|
|
|
|
**Files**: All StatefulSet files (validators, sentries, RPC)
|
|
|

|
|
|
|
## High Priority Issues (Weeks 2-3)
|
|
|
|
### 6. Terraform Backend Configuration 🟠
|
|
|
|
**Issue**: Backend is commented out, no remote state management.
|
|
|
|
**Impact**: State file conflicts, potential data loss, no state locking.
|
|
|
|
**Solution**: Configure Azure Storage backend with state locking.
|
|
|
|
**Files**: `terraform/main.tf`
|
|
|
|
---
|
|
|
|
### 7. Missing Resource Limits 🟠
|
|
|
|
**Issue**: Init containers and some services lack resource limits.
|
|
|
|
**Impact**: Resource exhaustion, node instability, cost overruns.
|
|
|
|
**Solution**: Add resource requests and limits to all containers.
|
|
|
|
**Files**: All StatefulSet files, Helm chart templates
|
|
|
|
---
|
|
|
|
### 8. Security Configurations 🟠
|
|
|
|
**Issues**:
|
|
- CORS allows all origins (`*`)
|
|
- No IP allowlisting for admin operations
|
|
- Missing WAF rules
|
|
- No DDoS protection
|
|
|
|
**Impact**: Security vulnerabilities.
|
|
|
|
**Solutions**:
|
|
- Fix CORS: `rpc-http-cors-origins=["https://yourdomain.com"]`
|
|
- Add IP allowlisting in nginx config
|
|
- Configure WAF rules in Application Gateway
|
|
- Add Azure DDoS Protection
|
|
|
|
**Files**: `config/rpc/besu-config.toml`, `k8s/gateway/nginx-config.yaml`
|
|
|
|
---
|
|
|
|
### 9. Monitoring Integration 🟠
|
|
|
|
**Issues**:
|
|
- Prometheus service discovery may not work correctly
|
|
- No ServiceMonitor CRDs
|
|
- Grafana dashboards not deployed
|
|
- Alertmanager not configured with real notification channels
|
|
|
|
**Impact**: Limited visibility into system health.
|
|
|
|
**Solutions**:
|
|
- Use Prometheus Operator
|
|
- Create ServiceMonitor resources
|
|
- Deploy Grafana with dashboards
|
|
- Configure Alertmanager with Slack/PagerDuty
|
|
|
|
**Files**: `monitoring/*`
|
|
|
|
---
|
|
|
|
### 10. Smart Contract Security 🟠
|
|
|
|
**Issues**:
|
|
- Proxy contract is simplified
|
|
- No OpenZeppelin Contracts usage
|
|
- Limited test coverage
|
|
- Missing security best practices
|
|
|
|
**Impact**: Security vulnerabilities, bugs.
|
|
|
|
**Solutions**:
|
|
- Use OpenZeppelin Contracts for proxy and access control
|
|
- Add comprehensive tests
|
|
- Conduct security audit
|
|
- Implement access control patterns
