How to Generate and Deploy Offline Package#

Overview#

The Offline Package Generator creates self-contained deployment packages for Metro Vision AI applications that can be deployed in environments without internet connectivity. This tool is specifically designed for environment with no internet connectivity where traditional cloud-dependent deployments are not feasible.

Prerequisites#

System Requirements#

  • Operating System: Linux (Ubuntu 20.04 or later)

  • Docker: Version 20.10.0 or higher

  • Docker Compose: Version 2.0.0 or higher

  • Storage Space: Minimum 15 GB available disk space

  • Memory: 8 GB RAM recommended

  • Internet Connection: Required for package generation only

Important: This process requires two environments - a connected system for package generation and an offline target system for deployment.

Perform this step on a system with internet connectivity

Objective: Create a complete offline deployment package containing all necessary components for the Smart Parking application.

# Navigate to the Smart Parking application directory
cd edge-ai-suites/metro-ai-suite/metro-vision-ai-app-recipe/smart-parking

# Execute the offline package generator
./offline-package-generator.sh

What happens during generation:

  • Downloads and packages all Docker images (~2-3 GB)

  • Collects AI models and sample videos (~500 MB)

  • Gathers Grafana plugins and configurations (~100 MB)

  • Prepares deployment scripts and documentation

  • Creates a complete offline-package/ directory

Success indicator: You should see:

✓ Docker is available and running
✓ Docker Compose is available
...
Offline package generation completed successfully!
Package location: ./offline-package

Step 2: Prepare Package for Transfer#

Package the generated files for secure transport to offline environment

Objective: Create a compressed, transferable archive optimized for offline environments.

# Create a timestamped compressed package for easy identification
tar -czf smart-parking-offline-$(date +%Y%m%d-%H%M).tar.gz offline-package/

# Verify package integrity and size
ls -lh smart-parking-offline-*.tar.gz
tar -tzf smart-parking-offline-*.tar.gz | head -10

# Generate checksum for integrity verification
sha256sum smart-parking-offline-*.tar.gz > package-checksum.txt

Transfer the tar.gz package and checksum file to your offline environment:

# Both files need to be transferred together for integrity verification
# - smart-parking-offline-YYYYMMDD-HHMM.tar.gz (main package)
# - package-checksum.txt (integrity verification file)

Transfer options for offline environments:

  • USB/External drive: Copy files to removable media

  • Secure network: Use SCP, SFTP, or approved file transfer protocols

  • Physical media: Burn to DVD/Blu-ray for highly secure environments

  • Satellite/RF links: For remote locations with limited connectivity

Step 3: Deploy in Offline Environment#

Execute deployment on the target system without internet connectivity

Objective: Deploy and start the Smart Parking application in a completely offline environment.

3.1 Extract and Prepare#

# Extract the package on target system
tar -xzf smart-parking-offline-*.tar.gz

# Verify extraction integrity
sha256sum -c package-checksum.txt

# Navigate to extracted package
cd offline-package/

# Verify all components are present
ls -la

3.2 Load Docker Components#

# Make scripts executable
chmod +x load-images.sh

# Load all Docker images (this may take 10-15 minutes)
./load-images.sh

# Verify images loaded successfully
docker images | grep -E "(grafana|influxdb|nginx|dlstreamer)"

3.3 Start the Application#

# Start all services using Docker Compose
docker compose up -d

# Monitor startup progress
docker ps

Next Steps: Proceed with steps to run the application using the get-started-guide for detailed instructions.
