For dev installation you should run:
npm install --arch=x64 --platform=linux
Check docker-compose.yml to create a similar setup or to run this container in dev mode. Change volume mappings to your needs.
Current docker-compose is running the service in dev mode. Access the service on your local machine: http://localhost:8081
Call http://localhost:8081/stats to get statistics about the module usage.
Call http://localhost:8081/images/1.jpg - you should get an original image.
Call http://localhost:8081/images/800x600/1.jpg to get the same image resized to 800x600
