saveimages

Storing high quality medical images into a structured File System

this frontend runs against a pseudo distributed node of HDFS

Attention: every command mentioned in this readme should be run in the project folder

prerequisites

install backend

• install docker
• run docker-compose up -d in project folder to spin up the hadoop image and the backend image

In case you get an error that one or multiple ports are in use, you'll need to change the port mapping in the following way:

• run docker-compose stop
• open docker-compose.yml You'll see a long list of port mappings. The first number is the port on your system, the second is the port inside of the docker container.
• change the affected port (keep in mind to only change the first of the two numbers, as a change of the second number will break the application)
