# Quick Fixes and Immediate Actions
|
||||
|
||||
## Critical Fixes (Do First)
|
||||
|
||||
### 1. Fix Genesis ExtraData Generation
|
||||
|
||||
**File**: `scripts/generate-genesis.sh`
|
||||
|
||||
**Issue**: Script doesn't generate proper QBFT extraData
|
||||
|
||||
**Fix**: Create a proper genesis generation script that uses Besu's operator tool:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Generate proper QBFT extraData using Besu operator
|
||||
|
||||
besu operator generate-blockchain-config \
|
||||
--config-file=config/genesis-template.json \
|
||||
--to=keys/validators \
|
||||
--private-key-file-name=key.priv
|
||||
|
||||
# Extract extraData from generated genesis
|
||||
# Update config/genesis.json with proper extraData
|
||||
```
|
||||
|
||||
### 2. Pin Image Versions
|
||||
|
||||
**Files**:
|
||||
- `k8s/base/validators/statefulset.yaml`
|
||||
- `k8s/base/sentries/statefulset.yaml`
|
||||
- `k8s/base/rpc/statefulset.yaml`
|
||||
- `k8s/blockscout/deployment.yaml`
|
||||
- `monitoring/k8s/prometheus.yaml`
|
||||
- `helm/besu-network/values.yaml`
|
||||
|
||||
**Fix**: Replace `:latest` with specific versions:
|
||||
|
||||
```yaml
|
||||
image: hyperledger/besu:23.10.0
|
||||
image: blockscout/blockscout:v5.1.5
|
||||
image: prom/prometheus:v2.45.0
|
||||
image: busybox:1.36
|
||||
```
|
||||
|
||||
### 3. Remove Hardcoded Secrets
|
||||
|
||||
**File**: `k8s/blockscout/deployment.yaml`
|
||||
|
||||
**Fix**: Remove hardcoded secrets, use Kubernetes Secrets:
|
||||
|
||||
```yaml
|
||||
# Remove this:
|
||||
stringData:
|
||||
secret_key_base: "change-me-in-production"
|
||||
postgres_password: "change-me-in-production"
|
||||
|
||||
# Replace with:
|
||||
# Generate secrets using:
|
||||
# kubectl create secret generic blockscout-secrets \
|
||||
# --from-literal=secret_key_base=$(openssl rand -hex 32) \
|
||||
# --from-literal=postgres_password=$(openssl rand -base64 32)
|
||||
```
|
||||
|
||||
### 4. Fix Health Checks
|
||||
|
||||
**Files**: All StatefulSet files
|
||||
|
||||
**Issue**: Besu may not have `/liveness` and `/readiness` endpoints
|
||||
|
||||
**Fix**: Use metrics endpoint or implement custom health checks:
|
||||
|
||||
```yaml
|
||||
livenessProbe:
|
||||
httpGet:
|
||||
path: /metrics
|
||||
port: metrics
|
||||
initialDelaySeconds: 120
|
||||
periodSeconds: 30
|
||||
|
||||
readinessProbe:
|
||||
httpGet:
|
||||
path: /metrics
|
||||
port: metrics
|
||||
initialDelaySeconds: 60
|
||||
periodSeconds: 10
|
||||
```
|
||||
|
||||

||||
|
||||
**Files**: All StatefulSet files
|
||||
|

**Fix**: Add resource limits to init containers:
|
||||
|
||||
```yaml
|
||||
initContainers:

||||
- name: config-init
|
||||
resources:
|
||||
requests:
|
||||
cpu: "10m"
|
||||

||||
limits:
|

memory: "64Mi"
|
||||
```
|

||||
storage_account_name = "tfstate${random_id.storage.hex}"
