Distributed Image Encrypter

Description

Encrypts the image using DES algorithm using parallel and distributed computation with the help of Docker Swarm.

Requirements

• 2 machines running Ubuntu 18.04/16.04 OS
• Docker CE

How to run

1. Build the docker image - ./setup-docker.sh
2. Change SERVER_IP in .env file to your system's IP (can find via ifconfig)
3. Change hostname in line 17 and 41 of system to that of two machine's hostnames
4. Initialize docker swarm and create the network - ./create-network.sh
5. Deploy the server using the command - docker stack deploy -c docker-compose.yaml test
6. See the logs of both services by using docker logs -f <SERVICE_NAME> command. Replace the service name with the container id found by running docker ps
7. Run the following command in the host PC - curl 0.0.0.0:3000/encrypt
8. You will be able to see the logs on the console, the encrypted image will be output to /tmp/output.jpeg path.
9. If you want to change the input image, simply replace original.jpeg with another image but with the same name, and repeat from step 1.
