🎯 Use Cases

🔧 Local Development & Testing (Primary Use Case)

This tool is designed for local development environments where developers are:

• Building and testing Splunk apps locally
• Iterating on app configurations and dashboards
• Validating app structure and functionality
• Learning Splunk app development concepts

# Development workflow - multiple apps, restart once at the end
python3 splunk_app_deployer.py  # App 1, choose 'n' for restart
python3 splunk_app_deployer.py  # App 2, choose 'n' for restart
python3 splunk_app_deployer.py  # App 3, choose 'y' for restart

🧪 Testing & Validation

Suitable for controlled testing environments:

• Development Splunk instances
• Testing new app versions before production
• Validating app compatibility and functionality

# Testing deployment with validation
python3 splunk_app_deployer.py --splunk-home /opt/splunk-dev --restart

⚠️ Production Deployments (Not Recommended)

While this tool can be used for production, we strongly recommend implementing proper CI/CD pipelines for production deployments that include:

• Automated Testing: Unit tests, integration tests, and validation checks
• Code Review: Peer review and approval processes
• Deployment Approval: Manual approval gates for production changes
• Rollback Capabilities: Automated rollback on deployment failures
• Monitoring & Alerting: Deployment success/failure monitoring
• Audit Logging: Complete deployment audit trails

Recommended Production Tools:

• GitLab CI/CD or GitHub Actions for automation
• Splunk REST API for programmatic deployments
• Ansible or Terraform for infrastructure-as-code
• Splunk Deployment Server for large-scale app distribution

🖥️ Platform Support

Platform	Status	Default Splunk Path	Notes
Linux	✅ Full Support	/opt/splunk	Systemd integration
macOS	✅ Full Support	/Applications/Splunk	Launchd integration
Windows	✅ Full Support	C:\Program Files\Splunk	Services integration

🔄 Restart Management

The tool includes comprehensive restart guidance that explains:

• Why Splunk restart is required (based on official documentation)
• What happens during restart (step-by-step process)
• How to verify successful deployment (validation checklist)
• When NOT to restart (timing considerations)
• Manual restart options (OS-specific commands)

📊 Command Line Options

Usage: python3 splunk_app_deployer.py [OPTIONS]

Options:
  --splunk-home PATH      Path to Splunk installation directory
  --splunk-apps-dir PATH  Target apps directory (default: SPLUNK_HOME/etc/apps)
  --restart              Automatically restart Splunk after deployment
  --help, -h             Show help message

Examples:
  python3 splunk_app_deployer.py                    # Full interactive mode
  python3 splunk_app_deployer.py --restart          # Interactive with auto-restart
  python3 splunk_app_deployer.py --splunk-home /opt/splunk --restart  # Fully automated
