```bash
GITEA_TOKEN          # Gitea access token for container registry
SLACK_WEBHOOK_URL    # Optional: Slack notifications
STAGING_WEBHOOK_URL  # Optional: Staging deployment webhook
PRODUCTION_WEBHOOK_URL # Optional: Production deployment webhook
```

### **Environment Variables**

Key environment variables used across workflows:

```yaml
PYTHON_VERSION: '3.11'           # Default Python version
REGISTRY: git.b4l.co.th          # Container registry
IMAGE_NAME: grabowski/northern-thailand-ping-river-monitor
```

## 🚀 Usage Examples

### **Triggering Workflows**

**Manual CI/CD Run:**
```bash
# Push to trigger CI/CD
git push origin main

# Create pull request to trigger testing
git checkout -b feature/new-feature
git push origin feature/new-feature
# Create PR in Gitea UI
```

**Manual Security Scan:**
```bash
# Trigger via Gitea Actions UI
# Go to Actions → Security & Dependency Updates → Run workflow
```

**Creating a Release:**
```bash
# Create and push a tag
git tag v3.1.1
git push origin v3.1.1

# Or use manual dispatch in Gitea Actions UI
```

### **Monitoring Workflow Results**

**Check Workflow Status:**
1. Navigate to your repository in Gitea
2. Click on "Actions" tab
3. View workflow runs and their status

**Download Artifacts:**
1. Click on a completed workflow run
2. Scroll to "Artifacts" section
3. Download reports and logs

**View Security Reports:**
1. Go to Security workflow runs
2. Download security-reports artifacts
3. Review JSON reports for vulnerabilities

## 🔍 Troubleshooting

### **Common Issues**

**Workflow Fails on Dependencies:**
```bash
# Check requirements.txt for version conflicts
pip-compile requirements.in
```

**Docker Build Fails:**
```bash
# Test Docker build locally
make docker-build
docker run --rm ping-river-monitor python run.py --test
```

**Security Scan Failures:**
```bash
# Run security scans locally
safety check -r requirements.txt
bandit -r src/
```

**Test Failures:**
```bash
# Run tests locally
make test
python tests/test_integration.py
```

### **Debugging Workflows**

**Enable Debug Logging:**
Add to workflow file:
```yaml
env:
  ACTIONS_STEP_DEBUG: true
  ACTIONS_RUNNER_DEBUG: true
```

**Check Workflow Logs:**
1. Go to failed workflow run
2. Click on failed job
3. Expand failed step to see detailed logs

**Validate Workflow Syntax:**
```bash
# Validate YAML syntax
make validate-workflows
```

## 📈 Performance Optimization

### **Caching Strategy**
- **Pip Cache**: Cached across workflow runs
- **Docker Layer Cache**: GitHub Actions cache for faster builds
- **Dependency Cache**: Cached based on requirements.txt hash

### **Parallel Execution**
- **Matrix Builds**: Multiple Python versions tested in parallel
- **Independent Jobs**: Security scans run independently of tests
- **Conditional Execution**: Jobs skip when not needed

### **Resource Management**
- **Timeout Settings**: Prevent hanging workflows
- **Resource Limits**: Appropriate runner sizing
- **Artifact Cleanup**: Automatic cleanup of old artifacts

## 🔒 Security Best Practices

### **Secret Management**
- Use Gitea repository secrets for sensitive data
- Never commit secrets to repository
- Rotate secrets regularly
- Use least-privilege access tokens

### **Container Security**
- Multi-stage Docker builds for smaller images
- Non-root user in containers
- Regular base image updates
- Vulnerability scanning before deployment

### **Code Security**
- Automated security scanning in CI/CD
- Dependency vulnerability monitoring
- License compliance checking
- Code quality enforcement
