How to RUN with DOCKER
Run the docker command:
docker-compose up --build
After docker finishes building we call this address: http://localhost:3000/image/eye.jpg/600x300
And then this address: http://localhost:3000/image/cat.jpg/600x300
And then this address: http://localhost:3000/image/dog.jpg/600x300
